Fiber cement panels for exterior home decoration have been used in modern construction relatively recently. Their popularity is gained by convenience and ease of use. Their task is to carry out all the functions of protecting the house from temperature extremes and the effects of adverse weather conditions. Among other things, these panels are an element of decorative decoration of the facade of any private building.
Fiber cement panels: composition and properties
Facade panels of this type are durable varieties of finishing building materials. The basis of such plates is a highly durable cement composition with the addition of reinforcing substances. The additive is only 10%, it may consist of fiberglass, cellulose or other mineral components. However, even such a small amount is sufficient to provide products with high strength, some flexibility and resistance to external influences. Outside the panel is covered with additional layers of acrylic or other compounds.
For the first time fibrotsementny panels for exterior finish of the house began to be used in Japan, therefore even now they are called Japanese. Russian enterprises have long since established production of such products, which are distinguished by excellent textural variations and a variety of color palettes. Cement panels are suitable for arranging the facades of any public and private buildings. Due to their flexibility, they can be used for facing complex architectural structures. They are quite convenient to veneer dilapidated buildings, since this method of facade decoration does not require prior cleaning of old surfaces or leveling.
Front panels are made of such material as fiber cement using an autoclave and a press. Quality products are obtained by pressing under high pressure. His figure should exceed 600 N / cm ?. The temperature in the autoclave varies in the range from 165 to 175? С. Under such conditions of production, the structure of the panels is quite homogeneous and stable.
The final stage of the manufacturing process is staining. To do this, use different types of paint: textured or plain smooth. Using texture paint make panels that mimic wild or artificial stone. To protect the finished product from exposure to harmful sunlight and various precipitation, they are covered with a special protective composition. And for greater similarity with stone slabs sprinkled with crumb.
Helpful advice! When choosing fiber cement plates, it is necessary to calculate the total weight of the future structure. Heavy panels can give a fairly large load on the walls, as well as the foundation of the building.
Any finishing material has its positive qualities and some disadvantages. The advantages of fiber cement boards include:
- extended service life (approximately 20 years);
- environmental friendliness;
- resistance to adverse conditions;
- powerful heat and sound insulation properties;
- increased fire resistance.
Due to such a large number of positive qualities, the use of fiber cement panels for exterior home decoration is becoming more common. But the disadvantages and disadvantages of this material also exist. These include a fairly large mass. The weight of a conventional panel, depending on the thickness of the products, varies from 10 to 14 kg per square meter. Working with such heavy plates alone is pretty hard.
Another drawback can be considered a high rate of absorption of moisture. Such a material can absorb up to 10% of water, as a result there may be a slight deformation, which does not affect the strength. The disadvantages can also be attributed to the impossibility of cutting panels with a regular knife or hacksaw. For quality sawing necessarily need a power tool.
Helpful advice! Cutting plates can be done with the help of an ordinary grinder, using a special stone for concrete.
Installation of fiber cement panels for the exterior of the house is made on the principle of a ventilated facade. The hinged mounting method allows laying mineral insulators under the exterior for greater thermal insulation of the interior. The framework for such slabs must meet several requirements.
- The frame should be made of special profiles, of which equip the crates.
- The base for fiber cement panels is securely fastened to the wall of the house. To perform this task, use special fasteners (brackets), which are additionally separated from the wall by pieces of gasket material.
- Mounting brackets made with a certain pitch. Vertical – 100 cm, horizon – 60 cm.
- If additional warming of the house is required, then the laying of heat-insulating plates is made in the intervals between the frame profiles. It is additionally attached to the wall with the help of “fungi”.
Installation of fiber cement panels for exterior home decoration also has its own characteristics. To prevent the foundation from getting wet, the basement is installed with the outflow arrangement. Its height is usually 50-100 cm from the ground or the existing blind area. For reliable fixation of the first row of plates requires the installation of special clamps, which are installed directly above the base of the casting. With their help, fiber-cement products are firmly fixed to the vertical profiles of the frame with screws. Above the first row is mounted the next parallel of the clears, which will hold the plates installed above.
Helpful advice! Given the relatively large weight of each individual plate – the thickness of the profile used for the frame, as well as fasteners must be selected with a large margin.
For the installation of such plates around windows or doors, an additional frame is created, completely framing the structures from all sides. To do this, use a metal profile. Installation is also carried out by self-tapping screws. The edges of some slabs will need to be cut at a 45-degree angle for docking. In these places, after installation of the entire structure, it will be necessary to carefully walk with sealant.
For arranging openings, you can use a special decorative profile. It is attached to the box window or door, and then insert the panels into special grooves. The joints are usually hidden by additional staining. And protection against moisture is provided by sealant.
