It is used in the construction of interior lightweight partitions, suspended ceilings, wall cladding and refractory structures. Thanks to special cardboard and hydrophobic additives, it has the ability to absorb moisture in small volumes.
Moisture-resistant Knauf boards have a rectangular shape and consist of two layers of special cardboard with gypsum mortar with reinforcing additives among themselves, while the side edges of the strip are folded with the edges of the cardboard (face layer).
These plasterboards are manufactured with different edges. The main ones are: straight (DK), thinned (NK), thinned semicircular from the front side (NYK).
To form the core, Q4-brand gypsum binders are used in accordance with GOST 125-79. Another important component of KNAUF-gypsum plasterboards (GKL) is the facing cardboard, which is attached to the core using adhesives. Cardboard plays the role of both a reinforcing frame and an excellent base for applying any finishing material (plaster, wallpaper, paint, ceramic tiles, etc.). In terms of its physical and hygienic properties, cardboard is ideal for residential buildings.
