What can be cooked from squid: quick and tasty

In the photo: the frame serves as the basis for fixing the lining

Wherever you sheathed surfaces, whether it be a balcony, a bathhouse or a living room, first of all, a crate is constructed under the lining. In this review, we will figure out how to build a structure from a wooden bar and what nuances to pay close attention to. All recommendations have been tested in practice, therefore, using them, you will be able to carry out the work yourself.

Description of work

In order for the lathing for the lining to be strong and durable, it is necessary to follow a certain technology of work.

It consists of three stages:

Calculation and purchase of material.
Preparing the bar for use.
Installation of the structure.

Each step is important, so read the entire overview carefully to rule out mistakes when working.

The first stage is the calculation and acquisition of material

To work, we need a very simple set of materials:

Wooden block.
Fasteners. See the article.
Insulation (if necessary).

FEATURE 1: frame positioning step. Optimal distance between the elements of the lathing is from 40 to 60 cm. If the lining is thin, then it is better to place the bars more often, this will give the structure additional rigidity. The distance can be different if the length of the walls does not allow keeping the same spacing of the elements.
FEATURE 2: If there are openings, a bar must be fixed along the perimeter. If it comes O doorways, it is better to mount two racks at all to strengthen the system. It is advisable to fasten the guides from above and below.

FEATURE 3: when using, the thickness of the bar must be at least the thickness thermal insulation material... The most commonly used option is 50x50 mm or 50x40 mm.
FEATURE 4: When purchasing material, pay attention to its moisture content. It should be no more than 15%. Damp elements can deform or crack when dry, so they should not be used.

Draw an approximate lathing scheme with the element spacing and their location. This will allow you to accurately calculate the required amount of material and not buy an extra block.

FEATURE 5: insulation is calculated based on the area on which it will be mounted;
FEATURE 6: fasteners are selected based on the type of base. For concrete and brick, quick-assembly dowels are needed, for wood, self-tapping screws or nails are used.

Second stage - preparation of the bar

The finished material must be prepared accordingly.

The instructions for carrying out the work look like this:

STEP 1: the material should be put for a couple of days in a room that will be finished. This will allow the bar to acclimate so that its temperature and humidity are the same as in the room.
STEP 2: elements are treated with an antiseptic composition. This can be done with a regular brush, treating all surfaces in order. You can do otherwise and make a trough out of the boards, which is covered with foil. An antiseptic is poured there, and the bar is simply dipped, this option provides the highest quality protection.

STEP 3: while the products are drying, you can prepare the walls. To do this, markings are applied on the surface along the width of the arrangement of the racks. The work is done with a pencil and a level so that the lines are even. This will allow you to visually see how the structure will look and will simplify the work, you will not need to be distracted by controlling the correct position of the elements;

STEP 4: measurements are taken to determine the length of the bars. It is better to do this in several places, as the walls or ceiling may be uneven;

Do not forget to leave gaps of 5-10 mm so that the bar does not rest and deform when the temperature and humidity changes.

STEP 5: the bar is cut with a hacksaw or jigsaw. Here it is important to correctly mark the elements and cut them perpendicularly so that the ends are even. It is also advisable to treat the cut areas with an antiseptic so that the bar is completely protected from moisture and pests.

The third stage is the installation of the frame

Let's figure out how to make a crate for a lining with our own hands.

The workflow looks like this:

STEP 1: first you need to drill holes in the bar. The diameter depends on what kind of fastener will be used. At the same time, remember that it is better to make holes under the self-tapping screws to make them easier to tighten. Fasteners are located in increments of 40-50 cm, the minimum distance from the edge is 30 mm.

STEP 2: The attachment points are also marked on the wall, and, if necessary, drilling is performed. For work, a perforator with a drill of the appropriate diameter is used. Remember that for reliable fastening, the self-tapping screw or dowel must protrude into the surface by at least 50 mm. See also the article.

STEP 3: if the irregularities on the wall or ceiling are very significant, then it is easier to fix the bar with suspensions. They are located along the line every 50 cm and are fixed perpendicular to the crate. The price of such fasteners is low, so the project costs will increase slightly.
STEP 4: when fastening, the ends of the suspension are bent to the bar, after which it is leveled and fixed in the desired position. This option is very convenient because of its simplicity and accuracy, so you can level any base very quickly.

One of the obligatory elements of the roof arrangement is the lathing, which is the beams that are laid perpendicularly on the rafter legs. The lathing takes the load roofing material, transfers it to the rafters, and they transfer the pressure to the load-bearing walls. Competent installation of the lathing is a responsible and difficult task, the implementation of which is better to entrust to professional builders.

timber;
board;
plywood;

There are two types of roof battens:

The sparse lathing of the roof is characterized by a gap between the beams of a few centimeters

A continuous crate is laid on a sparse one. For this, fiberboard, laminated chipboard, boards can be used. The boards are laid at a distance of 1 cm from each other at an angle of 45 ° to the boards of the sparse sheathing. The gap between the boards is necessary in order to extinguish the thermal deformation of the wood. It is better to use a grooved aniseptic board.

The continuous layer may be the only one laid directly on the rafters.

The battens are single-layer and double-layer. The first layer must be laid parallel to the ridge, horizontally. The step can reach 50-100 cm. It can be the only one, or it can be used for flooring on top of the second layer.

Important ! The roof deck should not have sags or bumps, especially if a fragile long material is used as a roof, for example, slate.

The flooring must be strong enough to support the weight of the person. Otherwise, while walking on the roof, the fastenings and joints of the roofing parts are broken, and this leads to leaks.

How the installation of the lathing will be carried out largely depends on the material chosen for the roof. As an example, let's take one of the most popular materials - metal tiles.

Laying anti-condensation film

In cases where roof insulation is provided, an anti-condensation film will be needed, which will protect the insulation from condensation and blowing. Without the film, the sheathing and rafters are ventilated, and the attic will be cold. When arranging the lathing for metal tiles, such a film spreads on the rafters in horizontal stripes over the entire roof area with an overlap of 10-15 cm. It should not be pulled, the film should sag between the rafters. The structure is fixed with bars equal in cross-section to the width of the rafters with a thickness of 3 cm.

Installation of lathing for metal tiles

After completing the installation of the film flooring, you can proceed to the installation of the crate, on which the metal tile will be fixed. In cases where the laying of the film is not provided, the horizontal crate is made directly on the rafters. All used horizontal boards must be antiseptic. The cross section is 2.5-3 cm by 1-1.5 cm. Any inch can be suitable, but it is very important that the thickness of all boards being laid is the same. Correct selection the thickness guarantees a flat roof plane. Not only functionality depends on this, but also appearance at home. The only exception is the bottom board, which should be one and a half centimeters thicker than the others.

Important ! The bottom board is attached first. So that in the future the boards are not twisted, they are immediately fixed in two places with screws or nails.

Sheathing, ready for installation of metal tiles

Calculation of the pitch of the boards

The step is selected in accordance with the profile and type of metal tile. Usually the distance between the bars is indicated in the instructions and is calculated from the bottom of the first board to the top of the second. This value should be lower between the first two boards.

The size of the step is influenced by the size of the roof ledge behind the first bar and the slope of the roof slope. The step is calculated taking into account the drain. If it is attached to the frontal board, then 30 mm is added to the protrusion. The diameter of the gutter also affects the length of the ledge.

The material protrusion is counted either from the frontal board, or, if it is not there, from the rafter cut. The length to which the metal tile should be lowered depends on the roof slope. The steeper it is, the lower you have to lower the material.

Step-by-step installation instructions

For the rafters, a bar with a size of at least 50 * 150 mm is selected, for the lathing - with a cross section of at least 25 * 100 mm. The counter lattice can be made from a board 25 * 50 mm.

The rafter pitch is usually 600-900 mm.

A starting board is nailed along the eaves overhang, and it should not protrude beyond the overhang. To compensate for the difference in the levels of the support point of the tile modules, this board, as already mentioned, should be thicker than the others by a centimeter and a half.

The step between the board facing the cornice should be 50 mm less than the step between other boards. To check the correctness of this distance, two cutting boards are laid out on the ground, on which a tile element is superimposed. This is how it is determined whether the protrusion is sufficient, whether it can provide a normal flow of water. If the protrusion is larger than required, water will overflow through the gutter. If, on the contrary, it is less than the prescribed value, water will be blown out between the frontal board and the gutter. In addition, if the overhang is too long, the sheets may deform from excessive snow load.

The device for the lathing under the metal tile requires care

After completing the marking, the ridge and end strips are fastened.

The wind board is attached above the crate exactly to the width of the sheet of metal, that is, 35-55 mm, depending on its type.

In order to securely fix the ridge, boards of 25 * 100 mm are nailed at the connection points. This will help install it later.

If you plan to arrange a drain before installing the roof, you must install the brackets to which the gutters are attached. Brackets are installed on the bottom board with a pitch of 500-600mm.

First, the extreme brackets are mounted in such a way as to calculate the slope of the gutter for 1 meter of length (made 5 millimeters). Then the cord is pulled, along which the remaining brackets are attached. Also, a cornice strip is mounted on the roof overhang before the metal tile flooring.

The gutter is fixed on brackets, then the eaves strip is fixed so that its lower edge overlaps the edge of the installed gutter. In this case, condensate flowing down from the bar will fall into the chute. The overlap of the eaves must be at least 100 mm.

At the junctions (pipes, skates, valleys, roof windows etc.), a solid-type crate is installed.

After completing all the above operations, you can proceed to the direct installation of the metal tile.

The lathing is the basis of both the roofing and rafter systems of the house.

It is worth remembering that the service life of your roof depends on many factors, both on the quality of installation and on the service life of the components. Much depends on how correctly the lathing is installed: the appearance of the entire structure, the service life of the roof, the safety of the house, even the reduction of rain noise. And since its arrangement requires experience, knowledge of nuances and subtleties, it is desirable that professional installers be entrusted with its installation.

NOTE!

The lathing transfers the load to the rafters, which in the future she will experience from the weight of the roofing material and atmospheric precipitation (snow, ice and rain). The lathing is also designed to fully support the roof on the building.

Some of the following materials are required for the construction of the sheathing, depending on the roofing material:

timber;
regular or grooved boards;
plywood.

The device of the roof lathing must be carried out in accordance with the established construction rules. This is important because in the event of improper installation or non-observance of instructions, the entire roof may be on the ground due to gusts of wind or unfavorable weather conditions.

Roof lathing

Therefore, before starting work on the construction of the lathing, you must first completely understand the device, types of materials and the possibility of their application in specific cases.

Roof roofing device

No matter what kind of roof was planned buildings - flat or pitched, the roof must be carried out in a certain way.

This element of the structure consists of several layers, which the builders adopted to call.

It allows you to protect the interior of the building from the adverse effects of any environmental factors on them.

The following layers of the cake allow this to be achieved:

interior decoration;
film for roofing under the crate -;
directly myself.

Roofing cake

Each of the above layers, if installed correctly, performs its specific function. If you skip one of the parts of the roof, the rest of the elements will be more susceptible to different influences. external factors... In addition, the internal premises of the building will become less protected and more comfortable for living and operating.

Interior decoration is most often a layer of plasterboard and finishing coat, which can serve as plaster, wallpaper or paint. This part of the pie has only an aesthetic function. closing the inner layers of the roof.

The lathing is a special frame, on which the roofing material will be held in the future. On the inside of the roof rafters, a special vapor barrier film is laid, which prevents the penetration of vapors from the room into the cake.
Most often, insulation material is laid between the roof rafters... Its most popular types are and. The first type of insulation is fire resistant and more expensive. It requires a lot of human resources for installation. Styrofoam is susceptible to rapid combustion in case of fire, emits, melting, toxic substances, but at the same time it is more affordable and easier to install.
Waterproofing is a film that is placed on top of rafter legs. It does not allow the penetration of atmospheric precipitation into the room, and also prevents leakage into roofing cake condensation that may form in a ventilated space.
Ventilation in the roof is designed to make the rooms directly underneath it more comfortable for living and finding people in them. Also ventilation protects the roofing cake from water vapor.

Pie for metal tiles

Roofing material can be completely different - both piece and roll. Depending on which of the options presented will be chosen, the installation of the lathing also depends, since it is she who must hold it on the roof.

Features of solid and sparse lathing

What determines the pitch of the lathing in the roof structure? Depending on which roofing material was chosen for the roof, there are two different kinds lathing under it:

Solid roof sheathing- installation of boards of this design is carried out with a step that does not exceed one centimeter. The option of using plywood sheets is also allowed. Most often, such a crate is made for such types of roofing materials as and. Also all kinds of soft roofing fit exactly on this type of crate.
Sparse- installation of strips of this design can be different depending on the material, reaching several tens of centimeters. Most often, this type of lathing is used under, and.

In some cases, solid lathing can be used for other types of materials if heavy loads will be carried out on the roof. Sometimes boards or plywood in such cases are mounted in two layers.

Most often, the thickness of this type of lathing is 25 mm... One of the ideal types of lumber for this design is sheet piling.

Solid crate

The frame of a sparse sheathing is a series of boards or planks, parallel to the ridge of the roof and to each other with a certain pitch between each other. It can be completely different - from 10 to 800 millimeters.

Most often, for such a structure, a wider board is used for the roof sheathing. The minimum size of its cross section is within 40 millimeters. The heavier the roofing material is, the more reliable the frame needs to be made. Therefore, in some cases, the thickness of the boards is increased, and the pitch of their arrangement is reduced.

Characteristics of the material used for the lathing

In order to understand what material can be laid on the crate, you should first understand the characteristics of its most popular types. These include:

tile (ceramic,);
slate (), euro slate ();

Various types of tiles (except metal) are small piece roofing elements... This material is considered one of the best because of its properties, as well as its long service life.

Wherein shingle roofing is the heaviest, because of which it requires a good foundation in the wine of the rafter frame and the corresponding lathing. It is best to use bars with a cross section of 50 to 60 millimeters.

The step of the lathing must be calculated depending on the covering length of each shard, which can be different depending on the manufacturer.

Shingles

Slate is one of the most common roofing materials in the country for various reasons. Small size sheets can be placed on bars whose size does not exceed 50 millimeters.

If the installation of slate units that are large in size and weight is carried out, it is best to use blocks with a thickness of about 80 millimeters... The step must be selected depending on the size.

They can be either 120 * 68 centimeters or 175 * 112.5 centimeters. It is worth remembering that one sheet must be supported by at least three bars. so that it does not bend under its own weight and the pressure of atmospheric precipitation.

Seam roofing is less popular, but it is still sometimes used.... If the slope of the roof is within 14 degrees, or if its configuration itself is quite complex, manufacturers recommend to mount the material on a solid crate.

What kind of board is needed for the roof sheathing? The cross-section of the bar should be within 50 * 50 millimeters. You can also use a board instead. with a section of 32 * 100 mm.

You need to start the installation of the lathing under the folded roof from the eaves. The protruding parts of the roof should be finished with a solid board within 60 centimeters in increments of no more than 1 centimeter.

Seam roof

A soft roof is quite easy to install, but requires one- or two-layer solid sheathing... The weight of such material is quite small.

The cost, unlike some other types of roofing, is also quite acceptable. In this case, the service life of soft materials may not be very long. In addition, they are quite toxic when burning and not very fire resistant.

Flexible shingles

The choice of the pitch of the lathing depending on the roofing material

Each type of material used for the roofing of buildings must be mounted on the battens with a certain individual pitch.

This value often needs to be determined independently, depending on the dimensions of the sheets of material, while adhering to strict construction rules. The following patterns can be distinguished for different types roofs:

soft roll materials - you need to use a solid crate with a minimum step between its elements up to 10 millimeters;
slate- it is necessary to individually select the step depending on the thickness of the sheets - from 50 to 75 centimeters;
metal tile- the instructions of the manufacturer of the material should be taken into account, but in general it can be indicated that the total pitch is in the range from 300 to 400 millimeters, and the distance between the last two strips should be half the size;
roof tiles(ceramic, polymer and sand) - you need to follow the manufacturer's instructions, taking into account the angle of inclination of the blood; most often the boards are stacked with an interval of 320 to 380 millimeters;
folded roof- the most common lathing pitch is 200 millimeters, although there are others.

DIY roof lathing

After purchasing the material, you need to order wood for the roof.

The calculation of its dimensions must be made taking into account the dimensions of the roof that was purchased, as well as depending on the size of the roof.

It is worth remembering that the more complex the structure, the more there will be any waste and substandard elements.

Therefore, it is best to order material with a 10% margin.

The following tools may be needed to mount the base:

hammer and nails;
screwdriver and screws;
hacksaw or grinder;
pliers;
pencil or chalk for marking;
roulette;
building level.

Installation of waterproofing

During installation, follow the instructions below:

First, depending on the selected material, you should make markings on the rafter legs of the location of boards or bars... Depending on the type of roof, the markings may be heterogeneous. Most often a smaller step should be taken at the edges.
After the marking has been carried out, using a hammer and nails, or a screwdriver and screws, you need to carry out stage-by-stage installation boards or bars on rafter legs.
After each nailing of the next element, it is imperative to check its location relative to the previous one, and also correct installation using a level.
Already directly on the base itself, the installation of the roofing material should be carried out.

Conclusion

When installing the lathing for certain types of roofing materials, you must first of all be guided by the manufacturer's recommendations.

This is important due to the fact that in the modern world every year many new materials are invented and manufactured using new technologies, which is why the instructions for their installation are constantly changing.

If you strictly follow the instructions that the company has calculated, you can protect your home from precipitation and climatic conditions for a long time without any problems.

In contact with

It is impossible to equip a roofing system without lathing, the laying of which is carried out over the rafter legs. It serves as a place for direct attachment of the final roof cladding.

What does the roof consist of?

Thanks to the roof, the building not only receives a decorated appearance: it also has a protective function to prevent rain, snow, heat and cold from entering the ceiling. In addition, due to the roof, the impact is noticeably reduced. Wastewater on walls and basement surfaces, which significantly increases their service life. Most often, there are 2 or 4 slopes on the roof of the building: moreover, the second design involves several options for arrangement.

The regular gable roof includes:

Rafters... To connect these vertical or horizontal supports, a corner joint is usually used, equipped with bolts and brackets.
Mauerlat... This bar is located in a horizontal position. It rests on the individual elements of the rafters.
Overhangs... This is the name of the lower sections of the rafters.
Ridge... It is located on top of the structure, in the area where the rafters meet.
Lathing, counter-lathing... Basic parts for laying roofing materials and insulation.
Waterproofing and insulation materials... With their help, warm attics are equipped.
Roof decking... Can be hard or soft.

In general, the roof is divided into cold and warm subspecies. The first option provides for the installation of thermal insulation in the attic space: the roof in this scheme is not insulated. The second method involves laying insulation and waterproofing. Basically, this approach is used to design attic residential floors.

Purpose of the battens in the roofing system

Thanks to the crate, the following tasks are achieved:

There is a reliable fastening of the roofing materials.
In this case, the space between the roof and the insulation is well ventilated: this is especially important for adjacent areas of warm and cold roofing layers.
It is convenient to fix a layer of insulation and waterproofing on the roof lathing.
The rafter system receives overload protection in cases of heavy snow.

What tools and materials will be needed

Before making the roof lathing, you should prepare the following tools and materials:

First grade timber, 6 m long, without knots and other defects. The section is selected depending on which finishing material will apply. For metal tiles, you will need products with a section of 50x50 mm, metal roof equips with a beam of 60x40 mm. Ceramic tiles laid on a bar with a square section of 75x75.
You need to know which board goes to the roof lathing, what are the tolerances. Edged board 25x100 mm, 6 m long. Small flaws in the form of rare knots are allowed here. Some cases involve replacing boards with OSB boards, plywood or chipboard panels.
Hacksaw, chainsaw.
Polyurethane foam.
Hammer, puncher.
Large size bolts with nuts. Fastening is also carried out with staples and nails.
Building level, tape measure.

Varieties of roof sheathing

Studying the question of how to make the roof lathing correctly, it is important to know about the most popular system designs. Choice suitable option lathing directly depends on the used roofing material.

There are two main types of crate:

Solid... When laying the beams, a gap of 10 mm is assumed. They construct a continuous sheathing, usually for soft tiles, roll stacking, flat slate or metal shingles. To give the roof additional reliability, the structure is fixed on top of the eaves overhangs, as well as in the areas where the slopes adjoin. When making a choice in the direction of this crate, you need to prepare for a significant consumption of material.
Sparse... In this case, the gap between the timber can reach several centimeters, which is very convenient for laying natural tiles, metal sheets and wave slate.

We mount the roofing crate with our own hands

After the rafter system is fully equipped, a careful measurement of the roof is carried out. This is done with a rope, which makes it easier to measure the diagonals. When comparing two indicators, it is desirable that they do not differ from each other by more than 20 mm. If this tolerance is exceeded, subsequent work may encounter certain difficulties. Next, the vapor barrier and insulation are laid, in the form mineral wool or other suitable material.

Do-it-yourself roof lathing is assembled on top of a previously laid waterproofing film, when laying it, an overlap of 15 cm is observed.It is most convenient to mount the canvases from the top and down, taking the rafters for the directions. A construction stapler is suitable for fastening the film. On top of the rafters, the planks are stuffed to create a counter-lattice.

It is important not to forget about the ventilation gaps separating the film and the roofing material to be laid. Simply put, it is important to leave sagging when laying the film. The same method is used to separate the film and insulation. To simplify the task of how to correctly make the lathing on the roof, a lathing template is used, which is designed to strictly adhere to the design parameters.

If a soft roof is laid, then the installation of the lathing elements is carried out by the method of alignment and joining. To avoid subsequent deformation, solid construction must be fastened with special care, using at least two nails on each beam.

How to attach under roll material

For the installation of rolled canvases, you need a solid-type roof sheathing made of beams and boards with a thickness of at least 25 mm. In this case, the flooring must have a dense, without cracks, laying. The step of the lathing is chosen at least 15 cm, otherwise the roofing material will begin to deform. It is important to achieve the ideal smoothness of the lathing surface, with the obligatory sinking of the nail heads and screws deep into the wood.

How to make under a soft roof

Installation of soft-type roof sheathing occurs most often, due to the high popularity of this roof. Such material is inexpensive, and it is very easy to mount it. Here you will also need to equip a solid-type crate, which is equipped with a special calibrated board. Such a laying has a two-layer structure, while observing the maximum evenness of the joints.

Under these conditions, tongue-and-groove boards and roofing plywood, which have undergone preliminary antiseptic impregnation, have proven themselves well. To avoid damage soft roof in corner sections, the ends of the boards must be rounded.

Under the shingles

According to experts, it is tiled roofs that have the most optimal performance characteristics in terms of quality and durability. Usually these are single-layer structures, the crate for which is equipped with bars with a cross section of at least 6 cm.

The laying step is guided by the dimensions of the tiles used. Some situations involve the creation of a double sheathing, from the same material. To achieve the uniformity of the adhesion of the tiles, it is required to build the most even plane of the structure. This implies using a block of the same size.

What is the difference between the crate for slate and metal tiles

For arranging the lathing, one or two layers of laying can be used. The first option involves the use of a bar with a square section of 50 mm. The optimal step in this case is 50 cm, with the elements laying in a parallel direction to the ridge. If, instead of the usual corrugated slate, a unified profile is used, then the step can be increased to 80 cm, with an increase in the section of the timber to 75 mm. The main thing is that there should be at least three crossbars under each slate span.

The cornice is loaded most of all in this structure, so its thickness should be increased. Skates and overhangs are made with continuous flooring. To achieve an even distribution of the load and the density of the sheet stacking, the even beams are made thicker than the odd ones by 30 mm. In order for the structure to serve as long as possible, before attaching the lathing to the roof, all its wooden parts must be treated with special fire-fighting and antiseptic compounds (for more details: ""). To apply them, you will need a paint brush: impregnation is carried out in two layers.

To test the quality of the fire extinguishing agent, it is enough to chop off a small piece of treated wood and try to set it on fire. A well-protected material ignites only when exposed to an open flame: upon its removal, the substance immediately extinguishes.

Competent design and arrangement of the roof will be the key to both the aesthetic beauty of the house and its protection from all external influences. At the same time, it is important to achieve good quality each individual part of the roof structure. The lathing, despite its invisibility, plays a very important role, therefore, when arranging it, it is important to comply with all the necessary requirements and norms, how to make a roof lathing. Particular attention is paid to the selection of suitable building materials appropriate quality.

The roof is considered one of the foundations that ensure the comfort of the house, protection from the negative effects of atmospheric factors. That is why the process of its arrangement must be organized rationally and correctly down to the smallest detail. It is obvious that the laying of the material for the roof must be carried out in full compliance with the technical recommendations and the requirements of SNIP. The lathing and counter-lathing of the roof are one of the most important elements on which the reliability and quality of the equipped roof depends in the future.

One of them serves as the basis for the installation of the roofing material and creates a gap between the latter and the insulation layer, and with the help of the other they create additional ventilation ducts for the under-roof space. Therefore, the question "how to make a roof lathing" does not lose its relevance. In fact, this structure, laid out from a row of boards nailed to rafter system, is an "intermediary" between the roof covering and the enclosing structures. Among other things, through it, the roof load is evenly distributed over the supporting frame.

Types of battens depending on the roofing material

The battens (formwork) are of two types:
- sparse - they are used more often for sheet corrugated material, the minimum distance between the battens is 40–50 mm. As a material, a bar is used for lathing with a section of 50 by 40-50 or boards: width 10-20 cm, thickness 2.5-3 cm.
- solid- are made of grooved boards (2.5x10 cm), and nowadays they are more often made of moisture-resistant plywood or OSB3, with a gap between the parts of 1 cm.This type is mainly used for piece roofing materials.
As a rule, continuous formwork is performed as follows. A sparse form is mounted and a second layer of formwork is made on it. There are two variants of execution here:
- they are stuffed onto the sparse formwork, closely laying one to the other dry boards (preferably grooved). They should be located at an angle of 45 ° in relation to the first layer - the sparse formwork;
- on the first - sheet materials are attached, such as moisture-resistant plywood.
Thus, in order to lay the roof, it is necessary to make a special frame: first, repeating the pattern of the rafters, mount the counter-lattice, after which, already across them, the frame itself is nailed, on which the roofing is laid.

The structure of the frame is determined by the type of roof. For example, in the case of metal tiles, square-section bars (□ 50, □ 60) are used for installation, which are laid with a certain step. At the same time, a continuous flooring is made under the bituminous shingles or roll coating using waterproof plywood or thin boards.

These structural elements make it possible to make the roof covering from the selected material solid and provides the strength of the roof structure.

How to make a roof sheathing, which board to use and how to fix it

The installation of the frame under the flooring is carried out from materials such as: timber, plywood, boards (preferably grooved), tesa (in the case of a solid version). When choosing lumber, it should be at least second grade and without a single knot. Use unedged boards or timber is not recommended, as this may affect the quality of the future roof structure. In extreme cases, their edges will need to be cut off.

To avoid warping, the maximum width of the board should be 150 mm - using too wide can damage the roof.

If the lumber is not dry enough, over time the wood will dry out and the fasteners will loosen. All wooden elements of the supporting structure must undergo a mandatory antiseptic treatment, which will protect them from damage by pests and decay.

There is no such frame only in houses with flat roofs, for pitched roofs a similar construction is required. Moreover, the steeper the slope, the, say, the crate gable roof, has a smaller step.

For normal operation and durability of the roof structure, it is necessary to provide a specific humidity regime. Since houses are usually heated, if the roof is not made correctly warm air coming from the interior will settle in the under-roof space in the form of condensation.

Double crate mansard roof practically lifts the covering above the insulation layer and provides ventilation in the under-roof space. That is, water vapor and atmospheric moisture that have got there from the interior of the house are easily blown out, and the structure will thus be protected from decay.

Double decking must not have
- gaps larger than 6 mm (if this is not the case, then cover the gaps using strips of roofing steel);
- should not bend from the weight of a person;
- the boards should be docked on the rafters and staggered.
It is also important with what nails to nail the crate and how. They are hammered closer to the edges of the lumber, slightly sinking the caps into the wood. The length of the nails is chosen from the calculation - twice as long as the thickness of the board to be nailed. In this case, the consumption of nails for the lathing is 10 pcs / m 2.
