Multipor is a highly compressive strength, non-compressible mineral insulation board. It is particularly suited for load-bearing roof constructions such as parking roofs, balconies and patios, intensively used green roofs, maintenance and escape routes as well as roof systems with high fire protection or ecological requirements. Insulating pitched roofs, however, is also possible with Multipor boards. Insulating flat roofs places high demands on the insulating materials used. Flat roofs are subject to temperature variations ranging from extreme heat from sun radiation up to nearly +90 °C and winter temperatures down to -30 °C. The construction layers are also subject to mechanical loads, moisture and wind forces. Fire protection plays an increasingly important role for roof constructions.
