Gipsovolokno is a material made on the basis of fibreboard and plasterboard. It has a sufficiently high strength and meets the fire safety requirements. It comes in the form of rectangular sheets, sanded on one side. Gipsovolokonnyh plates «Knauf» can be the basis for a variety of types of flooring. As topcoat apply the following materials:
- parquet Board;
Floor plates «Knauf» you have the following options: thickness 12.5 mm, width 800 mm, length 1500 mm, weight 13 kg. They are the most comfortable placement of the panels, as they have fold, which speeds up the installation work.
Using dry screed floor «Knauf» you will get a strong, durable and smooth floors, and will be able to carry out this procedure with his own hands.
