The AP underlay is used for all types of floors where underfloor heating is used. The underlay provides acoustic insulation and has rectangular holes that ensure perfect distribution of warm or cold air from the system over the entire surface.
We use UP underlayment boards as a floor structure in dry systems and to reinforce the load-bearing capacity of the floor. UP board is used twice in thicknesses of 3 and 4 mm. The 3 mm UP board is laid over the system boards, while the 4 mm UP boards are laid and glued overlapping. Thus arranged, the panels have good mechanical and acoustic strengths and good thermal transmittance.

TOP (cement-fiber) underlayment boards are products for damp rooms, suitable for reconstruction and laying on wooden beam ceilings and remodeling in residential homes and public spaces.
The plate made of lightweight concrete stiffened with fiberglass is particularly strong, thanks to its low weight one element weighs about 16 kg and the optimal format 1500x500x20/25 mm .The plate has an overlap so as to facilitate installation when gluing or connecting with screws.
