How to fix a block house - instructions with a step-by-step description!

Block house is a facing material with which you can sheathe the inner and outer walls of the house. These boards have a striking, rounded profile that imitates a log. The radius of curvature can be different. Narrower and flatter panels are used for cladding interiors; a wide block of house is needed for facades.

Types of block house

Traditional block house is made from high quality wood.

Recently, cheaper models made of vinyl and metal have appeared on the market of finishing materials. They have the same name: "block house", but in fact they are a kind of vinyl and metal siding, which determines the technology of their installation.

Characteristics of a wooden block house

Wooden block house is a kind of wood lining and inherited from it all the design and installation features. As a result, there are two longitudinal grooves on the back of the panels, which function as ventilation gaps.

Their presence is extremely important for cladding made of wood.

The natural material is "breathable", therefore it is necessary to ensure the possibility of removing excess moisture. Vinyl and metal panels do not need this.

The relatively high price of a wooden house block is explained by the peculiarities of its production technology. Its stages:

• 4 external parts are cut from each log suitable for the manufacture of facing panels;
• the resulting blanks are sent to the chamber drying (they achieve 10-12% moisture content of lumber);
• the blanks are sent for machining, at the stage of which the spikes and grooves are cut;
• ventilation grooves are cut out on the back side of the panels;
• form a rounded profile of the front side of the panel;
• Carry out shaving and grinding.

Dimensions of a wooden block of a house

The most popular dimensions of a wooden block house for exterior wall decoration:

• height (thickness) up to 6 mm;
• length from 140 cm to 4 m;
• width 142 mm.

The finished product may have deviations from the dimensions originally declared by the manufacturer:

• up to 0.5 mm in width;
• up to 3 mm in length.

Not all panels are manufactured in accordance with the accepted standard of sizes. Much depends on the characteristics of the base material: logs. Therefore, the market offers a house block of different dimensions: 27/140/2000 mm, 45/190/3000 mm, 36/190/1400 mm, etc.

Important to know: the number of panels in 1 m ³ depends on their size. The manufacturer has the right to vary the number of facing boards per cubic meter of finishing material so that the coverage area remains unchanged. For example, 1 m ³ house block with a length of 3 m contains 158 panels. And in 1 m ³ a house block with a length of 2.7 m will be 175 facing boards.

The area that they are able to cover, both in the first and in the second case, remains the same.

When buying a wooden house block, you need to pay attention to the radius of the profile. The higher the ridge, the fewer panels will fit into 1 m ³ . Accordingly, the cost of finishing the facade will be higher than when using a classic material.

House block with dimensions 36/193/6000 mm is considered the most profitable for outdoor decoration.

A cubic meter of this material is capable of covering 27.75 m ² of the facade area.

Grade of wood block of house

B Depending on the quality of wood, there are three types of block house: A, B and C.

Some manufacturers offer Extra class house blocks. This material does not have any flaws, but its cost is also quite high. According to consumer reviews, grade B panels are the most beneficial, since they have an affordable price and a small number of minor defects.

The biggest problem with wooden cladding boards is "dead" knots. They tend to shrink and fall out.

At this point, a through hole remains, which not only spoils the appearance of the facade decoration, but also causes heat leakage.

Resin pockets are no less a nuisance. They are most often found in pine products. These pockets exude resin, which absorbs dust and significantly reduces the aesthetic appeal of the façade cladding.

Choice of wood type block house

Block house is made from different types of wood.

The most common cladding panels are pine, larch, spruce, cedar, linden and black alder.

Of the conifers, the most inexpensive spruce and pine finishing boards.But they have a significant disadvantage, which is resin flow. However, spruce is not as resinous as pine. In addition, this wood (spruce) has a beautiful light texture.

Larch house block, which is also a coniferous tree, has a higher price because it has good strength and moisture resistance. Larch panels are favorably distinguished by a wide range of shades from light golden to pale red.

Block house made of alder is notable not only for its spectacular wood texture, but also for the unique property of this species to increase its strength with increasing moisture. As a result, alder boards have a long service life. Moisture resistant and durable panels are extremely beneficial for facade cladding in areas with high levels of air humidity.

Linden house block is known for its low thermal conductivity, therefore this material is often used for interior decoration of residential premises and baths. But it is also suitable for facades. Linden is good for the absence of resin pockets, light texture, smoothness and not splintering.

Cedar block house belongs to the elite of this group of finishing materials. Cedar is known for its unsurpassed crack resistance, has a beautiful texture, is non-tarry, strong and durable.

The facade made of cedar cladding panels has all the possible advantages, but it will require significant financial costs.

Technology of mounting a wooden block of a house

The walls of the house are not always even, therefore, it will not be possible to directly attach a block of house to them. First you need to build a crate, which will ensure the convenience and quality of installation. For the device of this frame, you can use both wooden and metal strips. But a wooden house block is traditionally attached to a wooden crate.

Selection of vapor barrier material

Depending on the type of the material from which the walls are built, the following types of vapor barrier are used:

• perforated polyethylene films;
• polypropylene films;
• foil-clad sheets;
• coating mastics;
• two- or three-layer membranes.

For brick and concrete walls, you can use coating materials, but it is worth considering that most of the compositions of this type are made on the basis of bitumen, therefore, when the wall is heated, the mastic can emit a weak, but specific smell. If there are households with a sensitive sense of smell, it is better to refuse this option for a vapor barrier device.

Inexpensive vapor barrier roll material - polyethylene and polypropylene films, which can be reinforced and unreinforced. For wooden walls, the best choice is Izospan V, which has good vapor barrier characteristics, but low strength.

Therefore, when laying it, you need to be extremely careful.

Roll materials are attached as follows:

• measure the height of the wall and cut the canvases of the appropriate length;
• alternately attach the canvases to the wall, observing an overlap of 10-15 cm (staples and a construction stapler are used);
• close the joints with a wide self-adhesive tape;
• the upper and lower edges of the film are fixed using a thin metal or wooden profile (or use the same staples and stapler).

If there is no need to install thick-layer thermal insulation, foil vapor barrier is an excellent choice. The most popular are "Penofol", "Armofol", "Alukraft". They are fixed in the same way as roll films.

The foil side should be directed towards the interior, this will ensure that the heat is reflected back into the house.

A modern and more expensive option is multilayer breathable membranes. The most popular products of the TechnoNIKOL company. Optima is the best choice for wooden walls.

Dorken Delta PLUS and Dorken Delta LUXX membranes have excellent characteristics.

The installation of these materials is similar to the installation of roll films, but it is important to consider the side of the sheets. Membrane manufacturers mark the front. It should not be directed to the supporting base (adjacent to it), but to the street.

Stages of installation of a wooden block house

Step 1. Preparation of the base.

Old finishing material is removed from the surface of the walls: plaster and old paint, which do not adhere well. They remove the platbands that decorate the door and window openings. They clean the wall from dust and remnants of old finishes.

Step 2. Installation of vapor barrier.

If membrane, film or foil material is selected, installation is carried out in accordance with the instructions above. If a coating vapor barrier is used, the mastic is applied with a brush or roller with a fur coat, not a foam rubber coat.

Step 3. Installation of the first tier of the battens.

Smooth, well-dried, antiseptic (covered with a layer of bioprotective composition) bars with a section of 40x40 mm, 40x50 mm or 50x50 mm are used for the frame.

At this stage of work, it is important to correctly calculate the distance between the vertical posts of the crate. Experts recommend focusing on the width of the insulating material that will fit between these supports.

If there is a need to level the wall, the bars are attached to metal suspensions, which are used when installing drywall. The hangers are thin and narrow perforated strips. Self-tapping screws are screwed through these holes.

In order to draw the plane of the wall, a long construction bubble level is required. If possible, use a level or laser level. The main thing is to ensure that all the frame racks are located in the same plane. The sequence of works:

• make up a drawing, which indicates the dimensions of the wall and the distance between the battens;

• along the lines corresponding to the location of the frame racks, suspensions are attached with a pitch of 40-45 cm (the upper and lower suspensions should be at a distance of 12-15 cm from the corresponding wall edge);
• strong threads are pulled at the top and bottom of the wall, which will determine the plane of the future frame;
• bend the "legs" of the suspensions and set the bar;

• fasten the block through the perforation of the legs "with self-tapping screws;
• fix the lower and upper parts of the frame with horizontal bars of the same section.

The crate with horizontally directed racks is also acceptable.

In some cases, this option is most convenient. The planks of the second level should always be located vertically, so it is more convenient to attach them to the horizontal, rather than vertical, supports of the first level of the batten. The block house assembly technology allows both options for the frame arrangement.

Step 4. Insulation laying.

For the insulation of walls sheathed with a block house, you can use both rolled and sheet materials. The most in demand are mineral wool and foam. Insulation is placed in the openings between the battens of the first level crate. Fastened with dowel nails.

Step 5.

Installing the windscreen.

To ensure the walls are protected from the wind, special films and membranes are used. "Tyvek", "Izospan", "Yutafol", "Ondutis A100" or "Ondutis A120" are recommended. Installation of windproof membranes is similar to the installation of vapor barrier films.

Step 6.

Installation of the second level of the wooden frame.

At this stage of work, the same materials are used as in the construction of the first tier of the lathing. But suspensions are not needed here.Wooden bars are attached with a pitch of 60-65 cm (if the first tier is mounted from horizontal strips) and directly to the posts of the first level of the crate (if its strips are vertical).

Step 7.

Mounting the house block.

Both horizontal and vertical mounting of the house block is possible. But the former is traditionally used. If you have experience with lining, installation of a house block will not cause difficulties. The principle of the decoration is the same.

1. A thread is pulled along the wall at the level of the lower edge of the first panel, which will be a guide when installing the first row of house blocks.
2. At an angle of 30 ° in the direction from the front side of the panel, saw off that end of it, which will border on the next to the laid panel on the right or left. This is necessary for a tight and even joining of the boards.
3. The first bottom panel is turned with the spike up, aligned with the thread and attached to the posts of the sheathing.

For facing the facade of the block house, additional elements will be required: decorative wooden strips, external corners and internal, platbands for the design of window and door openings.

An impressive appearance of the facade will provide a two-color tint of the boards. To do this, the house block is painted in a lighter color, and decorative elements in a darker color. Experts recommend toning (or varnishing) the house block twice: before and after installation.

Ways of fixing a wooden block house

The panels are fastened using self-tapping screws, staples or clamps. Self-tapping screws are more suitable for fixing a thick block of house.

If these fasteners are used, then they are screwed into the spikes. In this case, the board, which will be installed on top, will hide the self-tapping screw. This will not spoil the appearance of the finish.

The second option for fixing the house block on self-tapping screws is as follows:

• holes are drilled at the bottom and top of the panel for self-tapping screws;
• install the panel on the wall and fix it ;
• during the drilling of holes, sawdust is collected, which is mixed with PVA glue and smeared with the resulting gruel of the fasteners' caps and the recesses around them.

If brackets are used, their "legs" should be 5-7 mm longer than the thickness of the thorn.

To drive in staples, you need a sufficiently powerful construction stapler.

The most convenient mounting option is fastening to cleats. This is the name of metal plates with holes for the entry of nails and screws. Fastening with cleats is traditionally used for interior decoration. For facades, this installation method is convenient if the panels are thin and not wide.

The order of work:

• press the panel to the crate;
• from below fix the first board with self-tapping screws;

  

  Fix the first panel

• a kleimer is put on the shelf of the groove located in the upper part of the panel;
• with the help of nails they fasten the kleimer to the crate;

  

  Installing the second row

• insert the next board with a spike into the groove of the already fixed panel;
• knock the upper board with a wooden or rubber mallet so that its connection with the lower one is tight;
• repeat the installation steps until the entire wall is sheathed.

Arrangement of corners from a wooden block house

There are several options for the arrangement of internal and external corners from a block house. The most obvious is that it washed down the ends of the boards at an angle of 45 °. This method is inconvenient in that it is not always possible to achieve a tight joining of the panels. Cutting from a certain angle requires professional skill and special equipment.

Therefore, the method of cutting ends is rarely used.

Arrangement of an inner corner from a block house using the template

1. Sheath one of the adjacent walls completely.
2. A template is made from thin plywood or thick cardboard, one side of which must exactly repeat the profile of two panels installed side by side (one above the other). Next, cut the plywood from the bottom and top so that the template covers only 1/2 of the bottom and 1/2 of the top panel. That is, its width should correspond to the width of one full-fledged panel.

   If you put plywood (cardboard) perpendicular to the house block, there should be no gaps between them.

3. Lay the template on the canvas block of the house so that its curly side adjoins the end of the panel.
4. A template is drawn with a simple pencil.

   

   Methods of joining the block house

5. Along the line obtained, the end of the panel is cut using a jigsaw with a saw on wood.
6. Sets the house block.

   If necessary, the saw cut is finalized with coarse sandpaper.

   

   Perfect joining of inner corners

The outer corners of the cladding from the house block cannot be brought out using templates. For the decoration of these corners, additional elements are used: wooden decorative corners. But it will not be possible to install them close to the block house, so gaps will inevitably remain, but this corresponds to the installation technology.

Vinyl block house

For manufacturers The vinyl block of the house managed to repeat in this material not only the shape of a rounded log, but also the structure of the tree.

A house faced with such siding looks like a real log house.

Why is house vinyl block good? First of all, the fact that, unlike natural wood, it does not require such careful maintenance. Vinyl does not need to be painted or varnished. With him there will be no problems with the release of resin and harm from insects.

Of all the vinyl siding sold on the Russian market, the most spectacular one is from Holzplast.

But it costs no less than its natural counterpart - a log. However, during operation it will not cause any trouble.

Holzplast has developed a special system for fixing panels and additional elements for the Holzblock product line. It differs significantly from the one used to mount a standard vinyl house block. Therefore, when buying Holzblock siding, you will need to study the instructions that are attached by the manufacturer.

All other types of vinyl house block are attached to the facade according to the same rules.

Vinyl block house mounting technology

The installation of a vinyl block house is the same as for conventional siding. But there are some peculiarities that you need to know about for proper installation of panels.

The house vinyl block can be mounted from bottom to top or top to bottom. Installation in the direction from the bottom up is used in the event that it is not possible to determine exactly whether horizontal trimming of the panels is required.

This method of cladding is more convenient, therefore it is used more often.

When installing a wooden block of a house, connecting decorative strips are installed after sheathing the entire wall, and when laying vinyl - before installing the panels. Each canvas of a vinyl block of a house with both ends is wound over the connecting strips, and only after that is attached to the frame.

For a vinyl block of a house, not a wooden, but a metal crate is built. Its installation is carried out according to the same rules according to which a frame is built under a wooden house block.

Namely:

• all racks must be located in the same plane;
• hangers and self-tapping screws are used to install racks;
• vertical frame slats in the lower and upper parts of the wall connect horizontal.

Preparation of walls for cladding is carried out as follows:

• a vapor barrier membrane is attached;
• the frame is mounted;
• insulation is laid;
• over the heat-insulating material and the frame struts, a windproof film is laid;
• since the battens of the battens will be closed, they are duplicated with wooden bars, which are attached to each frame support along its entire length.

Thus, the ventilation gap required by the technology is obtained. After that, proceed to the installation of the vinyl block of the house. This will require not only panels imitating a log, but also a set of additional (finishing) elements, which includes:

• starting strip;
• finishing strip;
• connecting strip;
• J-chamfer;
• J-trim;
• outside corner;
• inside corner.

The procedure for finishing the facade with vinyl block house

1. Set the outer and inner corners.

   

   Installation of corners

2. Decorate window and door openings.
3. Install the tie bars.

   

   Installation of the H-profile

4. Start strips are fixed at the bottom of the wall.

   

   Setting the starting strip

5. A set of panels is performed, each of which must be located between adjacent connecting strips and inserted into them.

   First, one end of the house block is brought in, the panel is slightly bent away from the wall, and the second end is brought in.

6. A finishing bar is installed under the eaves.
7. Sheathed cornices and pediments.

   

   Installation of siding panels

The panels are fixed on self-tapping screws so that they are not tightly pressed against the crate ..

. This is necessary for the free running block of the house, which will slightly increase in size when heated by the sun and shrink at low temperatures.

Maintenance of this type of facade finishing material is simple: in the summer, it is washed with water from a hose or wiped with a damp cloth.
