Fiber cement panels for exterior decoration of the house began to be used in modern construction relatively recently. Their popularity is won by their convenience and ease of use. Their task is to perform all functions of protecting the house from temperature extremes and the effects of adverse weather conditions. Among other things, such panels are an element of decorative decoration of the facade of any private building.
What is fiber cement panels?
Facade panels of this type belong to durable types of finishing building materials. The basis of such slabs is a particularly durable cement composition with the addition of reinforcing substances. The additive is only 10% and can be composed of fiberglass, cellulose or other mineral components. However, even such a small amount is enough to provide products with high strength, some flexibility and resistance to external influences. Outside, the panels are coated with additional layers of acrylic or other compounds.
For the first time, fiber cement panels for the exterior of a house began to be used in Japan, therefore, even now they are called Japanese. Russian enterprises have long established the production of such products, which are distinguished by excellent texture options and a variety of color palettes. Cement panels are suitable for furnishing the facades of any public and private buildings. Due to their flexibility, they can be used for cladding complex architectural structures. They are quite convenient for revealing dilapidated buildings, since this method of facade decoration does not require preliminary cleaning of old surfaces or leveling.
Features of the production of fiber cement boards
Facade panels made of a material such as fiber cement are made using an autoclave and a press. High-quality products are obtained by pressing under high pressure. Its indicator should exceed 600 N / cm². The autoclave temperature ranges from 165 to 175 ºС. Under these conditions of production, the structure of the panels is sufficiently uniform and stable.
The last step in the manufacturing process is painting. For this, various types of paint are used: textured or plain smooth. Using texture paint panels are made that simulate wild or artificial stone. To protect the finished product from the effects of harmful sunlight and various precipitation, they are covered with a special protective compound. And for a greater resemblance to stone slabs, sprinkle with crumbs.
Useful advice! When choosing fiber cement plates, the total weight of the future structure should be calculated. Heavy panels can give a rather large load on the walls, as well as the foundation of the building.
Fiber cement panels for the exterior of a home: pros and cons
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 insulating properties;
- increased fire resistance.
Due to such a large number of positive qualities, the use of fiber cement panels for exterior decoration of the house is becoming more widespread. But such material also has disadvantages and disadvantages. A rather large mass can be attributed to them. The weight of a conventional panel, depending on the thickness of the manufactured products, varies from 10 to 14 kg per square meter. Working with such super heavy slabs alone is quite difficult.
Another disadvantage is the high moisture absorption rate. Such material can absorb up to 10% of water, as a result, slight deformation may occur, which does not affect the strength in any way. The disadvantages can also be attributed to the impossibility of cutting panels with an ordinary knife or hacksaw. For high-quality sawing, you will definitely need a power tool.
Useful advice! Slabs can be cut with a conventional grinder using a special stone for concrete.
The main features of the installation of fiber cement panels
Installation of fiber cement panels for the exterior of the house is carried out on the principle of a ventilated facade. The hinged installation method allows you to lay mineral insulation for external insulation for greater thermal insulation of interior rooms. The frame for such plates must meet a number of requirements.
Requirements for the arrangement of the frame
- The frame should be made of special profiles, from which they equip a kind of crate.
- The base for fiber cement panels is securely attached to the wall of the house. To accomplish this task, use special fasteners (brackets), which are additionally separated from the wall by pieces of cushioning material.
- Brackets are mounted with a certain step. Vertical – 100 cm, horizontal – 60 cm.
- If additional insulation of the house is required, then the installation of heat-insulating plates is made in the gaps between the profiles of the frame. It is additionally attached to the wall using “fungi”.
Installation of fiber cement panels
Installation of fiber cement panels for the exterior of the house also has its own characteristics. To prevent the foundation from getting wet, a plinth is installed with an ebb tide arrangement. Its height is usually 50-100 cm from the ground or existing blind area . To securely fix the first row of slabs, it is necessary to install special cleats, which are installed directly above the basement flashing. With their help, fiber cement products are firmly fixed to the vertical profiles of the frame with self-tapping screws. Above the first row, the next parallel of the clamps is mounted, which will hold the plates installed above.
Useful advice! Considering the rather large weight of each individual slab – the thickness of the profile used for the frame, as well as the fasteners, it is necessary to choose with a large margin.
Installation of fiber cement panels around windows and doors
For the installation of such plates around windows or doors, an additional frame is created that completely frames the structures from all sides. To do this, use a metal profile. Installation is also carried out with self-tapping screws. Some slabs will need to be trimmed at 45 degrees for joining. In these places, after the installation of the entire structure, you will need to thoroughly go through the sealant.
To equip the openings, you can use a special decorative profile. It is attached to a window or door box, and then the panels themselves are inserted into special grooves. Joints are usually hidden by additional staining. And protection against moisture is provided by sealant.
