The market of building materials is developing at an unthinkable speed! Even yesterday, builders and ordinary people admired the possibilities and characteristics of drywall, and today it is easily replaced by gypsum fiber sheet( GVL).What is this material and what advantages does it have over ordinary plasterboard?

What is gypsum fiber?
Due to the fact that the gypsum fiber sheet appeared quite recently, many people have a quite logical question: what is it? Gypsum fiber is a completely environmentally friendly finishing material, which is made of gypsum and cellulose. In fact, the process of manufacturing this building material is very simple: cellulose waste paper is mixed with gypsum and pressed. It is thanks to cellulose, GVL sheet is obtained very durable and durable.
The main application of gypsum fiber is, of course, construction and repair work. Such building material is used for the erection of partitions, walls, ceilings and other complex structures. In addition, gipsovoloknistye sheets are widely used for finishing the floor and creating its prefabricated basement.
Technical characteristics of GVL sheets
High technical characteristics of gypsum fiber are its main advantage. At the moment, the following main indicators can be singled out:
- Standard sizes - 2500х1200х10 mm, 2500х1200х12.5 mm;
- Weight - about 18 kg;
- Coefficient of thermal conductivity - 0,22-0,36 W / m * C;
- Hardness of the front surface - not less than 20 MPa;
- Bending strength - not less than 5.3 MPa.
Gypsum fiber sheets, depending on the field of application, are divided into standard( GVL) and moisture resistant( GVLV).Consider the characteristics of each species based on Knauf gypsum-fiber sheets.
Technical Specifications GVL:
Technical Specifications GVLV:
Properties
- Waterproof;
- Non-combustibility;
- Mold protection;
- Water vapor permeability;
- Low level of heat build-up.
Advantages of
The gypsum-fiber sheet has a number of undeniable advantages:
- Versatility. This material can be used in any type of premises. It is successfully used for finishing both ordinary residential buildings and special purpose buildings - schools, hospitals, kindergartens, etc.;
- Combination with other finishing materials. As consumers' reviews show, the GWL sheet shows itself perfectly in combination with different materials. It can be laid under any finish coating for the floor: laminate, parquet, tile, etc.;
- Highest durability. If a regular sheet of drywall can easily be broken and pierced with bare hands, then with a sheet of GVL such a trick will not work. Cellulose fibers make this material very durable, so it can easily withstand heavy loads, for example, from bulky furniture;
- Excellent level of resistance to moisture. Manufacturers can offer you two types of gypsum fiber - normal and moisture resistant. The second type of material can be easily used in rooms where it is constantly wet, for example, in the shower room;
- Ease of use. If you look at the photos and video reviews presented in this article, you will be able to independently verify the simplicity of this building material and ease of its application;
- Unstability to deformations. On the one hand, this is good, since gypsum fiber will be more resistant to mechanical damage, and on the other hand it's bad, because this material can not be used to create curly structures.
Disadvantages of
To be frank, the flaws in gypsum fiber are not so numerous. The first drawback is the high price. Sheet GVL will cost a little more expensive than drywall. The second disadvantage is that the gypsum fiber requires a mandatory finish with putty, however, like the GKL sheet.
