Biterm are sandwich panels with a foam core, lined with heat-welded asphalt roofing felt. The core of the boards is made of foamed polystyrene boards with compressive stress at 10% relative deformation of at least 80 kPa. The cladding of the panels is made of heat-sealable asphalt roofing felt on a veil of glass fibers. At the client's request, we also laminate Biterm asphalt roofing felt with other inserts. The panels can be glued on one or both sides.

Application:

• thermal insulation of roofing with a slope not exceeding 20%, on a concrete, wooden or trapezoidal sheet,
• thermal insulation foundation in.
