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.

Example of finishing the facade with 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.

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.
Wooden house block
The relatively high price of a wooden house block is explained by the peculiarities of its production technology. Its stages:
Scheme of manufacturing various types of wooden block house
Upper block house radius cutter with replaceable knives
The principle of operation of a four-sided machine
The most popular dimensions of a wooden block house for exterior wall decoration:
The finished product may have deviations from the dimensions originally declared by the manufacturer:
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.
House block, dimensions
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.
How to calculate the required amount of block of house
B Depending on the quality of wood, there are three types of block house: A, B and C.
|Wood defects|| |
|"Live" knots||Not more than 1 for every 1.5 m panels|| No more than 4 with a diameter of up to 2 cm for every 1. |
5 m panels
|Resin pockets||Not more than 2||Not more than 2||Diameter not more than 6 cm|
|Non-penetrating cracks||No more than 2||No more than 2||No more than 10% of the panel length|
|Through cracks||Not allowed||Impermissible||Not more than 5% of the panel length|

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.
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.

Wooden block 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.

Depending on the type of the material from which the walls are built, the following types of vapor barrier are used:
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.
Comparative table of characteristics of Isospan species
Roll materials are attached as follows:
How to fix the vapor barrier
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.
Alukraft vapor barrier
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.
Material for vapor barrier
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.
The entire decor must be removed from the facade
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.
Lubricating vapor barrier
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.
Wooden bar 50x50 mm
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:
Wooden lathing under siding
Installation of wooden lathing
Installing the guides
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.
Insulation for siding
Layout and fixing of the insulation
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.
Installing the windscreen.
Installation of wind protection
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.
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).
Mounting the counter grill
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.
Installation of the block house
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
How to properly attach a block house
Types of attachment 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:
Mounting the house block with your own hands
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:
Fix the first panel
Installing the second row

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.
An example of the outer corner decoration
Two walls are finished with a block house
Arrangement of an inner corner from a block house using the template
If you put plywood (cardboard) perpendicular to the house block, there should be no gaps between them.
Methods of joining the block house
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.
Finishing the facade of a private 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.
Wooden block house and PVC
Vinyl block 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 Vinyl Siding
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.
Types of vinyl siding
Vinyl block house
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.

Basic principles settings
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.
Preparation of walls for cladding is carried out as follows:
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:
Additional elements for the installation of block house siding
The procedure for finishing the facade with vinyl block house
Setting the special fixing profiles
Installation of corners
Installation of the H-profile
Setting the starting strip
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.
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.
