Common facade finishing technologies that involve the use of plasters cannot be called ideal. Even if all the rules for the work are observed, the cladding will have significant drawbacks. Before starting such manipulations, it is necessary to prepare the wall well, taking into account the absorbent properties of the material and the condition of the base. This takes a lot of money and time. Sometimes the work cannot be carried out independently, which entails additional costs for the services of specialists.
In winter, the wet process is not possible, so the bare walls after construction have to be left until the favorable time of the year. Even if the plaster is reinforced with a mesh, the shell will turn out to be quite thin, so it will quickly lose its appearance. The layer cracks and flakes off the wall when it freezes and gets wet. These shortcomings had to be put up with until the fiber cement board was invented. She first appeared in Japan.
Description of fiber cement panels
Fiber cement panelsare a finish that does not come into contact at a chemical level with wall materials, which means that it does not crumble or peel off. Products are quite dense, but very flexible, which eliminates their cracking. The shell is durable and resistant to external factors. The material is non-toxic and non-flammable.
Sheets provide easy mounting. Cement is the main component in the manufacture of fiber cement boards. It is resistant to moisture, heat and frost, and is also durable. In order to prevent the thin layer of the solution from becoming cracked, cellulose fiber is added to it. It plays the role of micro-reinforcement, which increases plasticity and perceives deformations.
The material has a textured variety. Prior to setting, the cement-cellulose composition can be given any shape. As a result, it is possible to obtain products with imitation of wild stone, brick or wood. This material is sold in a wide range of colors, which has been achieved thanks to alkali-resistant dyes. Hardened cement actively absorbs water, for this reason the facade panels are protected by a layer of silicone or varnish.
Description of Kedral products
If you want to finish the house with fiber cement materials, you can choose Cedar Click. These products are a board that is durable, resistant to frost and heat, as well as sudden changes in temperature. Cloths are more reliable than plastic. Installation is quite simple, and you can do such work around the clock.year.
At the base of the wall can be:
- SIP panels;
- foam concrete;
- frame structure;
- expanded concrete blocks;
- aerated concrete;
- wood;
- brick.
Fiber cement board has high moisture resistance, which makes it possible to clad facades in coastal areas. Products can be represented by one of two types of surface. You can choose the texture of natural wood or panels with a smooth surface.
Installation is carried out according to the principle of constructor assembly. Work does not take much time and effort. Using a fiber cement board for the facade with imitation of natural wood, you will give the walls of the house a natural warmth. The disadvantages inherent in wood finishes are excluded. This texture is the most advantageous, and you can combine it with other materials, namely:
- plaster;
- stone;
- brick.
Smooth board emphasizes an architectural idea or color zoning. This cladding will be ideal for connoisseurs of pure and simple forms. To install a fiber cement board, you only need:
- self-tapping screws;
- screwdriver;
- kleimers.
Special skills are not needed for this. Installation is much easier than installing any other finishing material. The cladding is UV resistant. The manufacturer guarantees that the finish will retain its original shade for 10 years.
Products are environmentally friendly. The material passes the appropriate test according toEuropean standards. The facade is made using dry technology, so installation can be done at any time.
Not only Cedar Click is supplied to the market, but also the Cedar board. The first differs from the second in the way of fastening. It allows you to hide the seams, which increases the level of aesthetics. Here you can take advantage of the freedom in the layout - install the boards horizontally or vertically. Wood products with a smooth texture have the same dimensions: 12x186x3600 mm. Before purchasing a product, it is important to consider the usable area of one board, it is 0.6264 m2.
Basic Features
The technical parameters of the described panels are standardized by GOST 8747-88. The density of this material is 1.5g/cm3. Its water absorption does not exceed 20% by weight. Frost resistance provides 100 freeze and thaw cycles, which is equal to approximately 40 years of operation.
Impact strength equivalent to 2 kJ/m2. The bending strength is 24 MPa. The average weight of one square meter can vary from 16 to 24 kg. Fiber cement board is quite often compared to asbestos-cement corrugated slate. The first resists bending forces better. This suggests that the material is able to withstand point impacts and intense wind loads.
In the construction market, panels are offered in a wide range of sizes. Production belongs to the category "fiber cement siding". The plates are quite long, this parameter can be equal to 1820 or 3030 mm. Widthsmall, it is 455 mm, while the thickness is equal to the figure from 12 to 18 mm. All these parameters correspond to Japanese-made plates.
As for European and domestic panels, they have different sizes. Their minimum width is 306 mm and the length is 1500 mm. When purchasing a Russian-made fiber cement board, you may prefer products with a thickness of 6 to 16 mm.
In addition to the parameters, the plates differ in the shape of the connecting edge. If you purchase products that are mounted on clamp plates, you will notice that the long sides have protrusions. They provide a snug fit to the frame. Canvases can be painted at the factory or sold without painting. In the latter case, after installation is completed, tinting is carried out at the facility.
Performing installation
The easiest way to install a fiber cement board is to mount it on a frame. It consists of planed wooden bars, the cross section of which is 5x5 cm. They are attached to the wall with dowels. Installation is carried out in such a way that the joints of the plates fall on the racks. The distance between the elements of the wooden crate is 60 cm.
The fiber cement board described above is mounted using stainless steel screws. They are screwed into the frame through the holes in the plates. The depth of installation of the screws should be such that their caps can be hidden using a colored paste in the form of a sealant. It is bought together with lining.
Products from fiber cement compositionhard, so their cutting is carried out using an angle grinder with a carbide disc. After installing the fiber cement board, the joints are treated with sealant so that moisture does not get into the space between the wall and the cladding.
Installation on a wooden frame is carried out not only with the help of self-tapping screws, but also with clamps. In this case, a plate with milled edges is purchased, which allows you to form a hidden seam. To ensure the tightness of the joints, a seam bar is fixed to the vertical racks of the frame. You can close the joint with a wooden bar, sealing the surface with a special tape.
Installation of panels using ventilated facade technology
Description of a fiber cement board is not all that a craftsman who plans to install the cladding should know. It is important to familiarize yourself with another technology - a ventilated facade. This technique is more complex. The number of crates is increased to two. The frame can be wood or metal. The first crate is fixed to the wall horizontally. Mineral wool slab insulation is installed between the bars.
Installation on self-tapping screws
Then a vapor barrier film is covered, on which the second frame is mounted. Its elements will be oriented vertically. Racks are attached to horizontal bars. This technology allows you to create an air gap between the plate and the insulation. Through it, water vapor is removed, whichpenetrates through walls from rooms.
The fiber cement board is fastened with self-tapping screws. Each of them must be installed with a deviation from the edge of 3 cm to prevent edge splitting. Before installing the cladding in the corners and around the openings, it is necessary to install docking profiles that will close the starting strips and the ends of the plates.
Features of mounting panels on a metal frame
Professional installation may include the installation of panels on a metal frame. Before fixing it to the wall, steel brackets are fixed. With the help of dish-shaped dowels, in the next step, it is necessary to strengthen the rigid thermal insulation and fix the horizontal load-bearing profile. This will also require brackets.
Plate mounting
The next step is to install the vertical crate. Only after this is the installation of a fiber cement board for the exterior of the house. The technique involves the use of an open method using clamping plates. They have hooks for fixing the edges. All seams between products after completion of work are covered with sealant.
Cost of fiber cement finish
The creators of the described cladding are the Japanese, so their companies occupy a leading position in the market. They sell quality material, the cost of which is not low. Two brands gained the greatest popularity: KEM Yu and Nichiha. The average cost of one square meter of such cladding is 1600 rubles.
Board of othersmanufacturers
Cedral fiber cement board is a product of one of the most famous brands. The plant is located in Belgium and supplies fiber cement siding, which costs 900 rubles. per square meter. But the stove can be purchased for 2500 rubles. for m2. Among Russian manufacturers, the following companies should be singled out:
- "Rospan";
- "Kraspan";
- "Latonite".
Products are of high quality, but cheaper than the Japanese counterpart. You can buy fiber cement cladding for 800 rubles. per square meter.
In conclusion
Fibercement facade panels are not only easy to install, but also easy to manufacture. The production technology is unique and provides for the creation of a homogeneous mixture of cement, sand, cellulose and water. The manufacturing technique is to drive out the remaining liquid from the raw materials to obtain a pasty substance.
The blanks are pressed under a multi-ton press to give the final products extra strength. Next, the canvases are sent to the autoclave or left in natural conditions until ripening.
