Guidelines and warnings
STIFERITE panels are suitable for use in paved roof systems thanks to their high compressive strength. The difficulty of carrying out maintenance once the work is complete requires the utmost care, both in design and installation, to ensure the watertight integrity of the system.
Depending on the panel chosen as an alternative to STIFERITE Class B, a suitable sealing element must be provided, depending on the application method.
STIFERITE panels have an elastic compressive strength exceeding 5,000 kg/m².
