  • Underlays

    The Underlays are applied (obligatorily in the buildings with attics) as initial covering layer, ensuring the heat, acoustic insulation, and, primarily, the protection against moisture. They play the significant role in ensuring the water resistance of roof sealing, and correct roof ventilation – they provide a perfect protection against the precipitation water entering into the roof places with sealing failures, drain the moisture entering the roof wall from outside of the building, and regulate the processes associated with water vapour condensation and condensate accumulation on the internal side of the roof covering.
