A roof is considered flat when it has a slope angle of seven degrees or less. It usually consists of a support structure, a vapor barrier, an insulation layer, a waterproofing layer and ventilation. Although flat roofs are usually used in factories and apartment buildings, nowadays more and more private house owners also choose flat roofs, because they allow to create additional useful space on them.
We offer construction boards for flat roof structure. Boards can be used both to be put on grids as support for the other layers (like insulation) or on solid base as a protective layer for the insulation from the layer that is melted on top (hydro isolation layer).
