alwitra insulation materials
roof insulation
Whether roof renovation or new construction: roofs place high demands on workmanship, also with regard to thermal insulation. It should be in top condition for future energy requirements, with the lowest possible installation height and minimized weight. With our high-performance and economical roof insulation, we are the ideal partner for roofers and carpenters. This saves time and costs during implementation and gives the builder what is most important to them: safety.
Hybrid insulation structure
The hybrid insulation structure combines the best of both worlds:
The EVAROC® rock wool insulation board in the top layer provides optimized fire protection, while the EVAPIR® insulation board made of rigid polyurethane foam underneath offers excellent thermal insulation.
This combination creates an innovative hybrid system from a single source with a slim profile, low weight, and good compressive strength—and all this as part of a complete roof structure.
For permanently secure and watertight roofs that impress in every respect—typical alwitra.
EVAPIR® and EVAPIR® G
EVAPIR® flat roof insulation boards made of rigid polyurethane foam (PIR) offer maximum thermal insulation with minimum installation height. The aluminum composite foil on both sides ensures high stability and protection. With an insulation value of WLS 023, they enable energy-efficient, lightweight roof solutions – ideal for lightweight industrial roofs and mechanically fastened roof systems.
