They are used in the construction of interior light partitions, suspended ceilings, wall cladding and refractory structures. Fire resistance is ensured by special additives.
Fire-resistant Knauf boards (GKLO) 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).
They 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 (GKLO) 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.
It differs from usual Knauf boards by special reinforced additives in the core material.
These gypsum plasterboards are manufactured in accordance with GOST 6266-97 and meets German standards (DIN 18 180).
