Insulation placed at flat ceiling level creates a cold roof space and overall is the lowest cost option for insulating a roof. Very high levels of thermal insulation can be achieved because there is virtually no restriction on the thickness of insulation that can be installed.

• Thermo Double Roll 0 40
• Thermo Slab 037

Thermo Double Roll 040 - roll material. If using slabs is more convenient, then Thermo Slab 037 can be used. These materials have outstanding thermal conductivity performance (the values are specified in their names). These materials are soft and elastic; they do not crumble or break, which preserves them in the course of the transportation and the operation. This makes it possible to avoid the development of "cold joists" in the course of the operation. These materials are easy to use, can be cut easily and do not require substantial physical effort in the course of the installation. The quality of materials, their safety for health and fire safety are confirmed with the certificates of conformity, hygienic fire safety certificates.
