Flat Roof Insulation

The roof is the most important part of the building envelope contributing to heat loss and energy efficiency, regardless of the type or slope. When you reduce heat loss through your roof, you need less energy to heat your entire house. 

Flat roofs are often defined as roofs that fall up to 1:10. Paroc has an extensive range of A1-classified stone wool products for insulation of fireproof and energy-efficient low-sloping roofs. The choice is between a solution that consists of only boards or a combination of boards or lamellas and slabs. This choice depends mainly on the desired U-value.

Taking into account the different local requirements, we have developed a large assortment of roof insulation slabs, lamellas, and boards with different thermal and mechanical properties. Our offering covers solutions for slope building products as well. With our solution you can renovate old roofs or build new energy-efficient roofs.
