Guidelines and warnings
STIFERITE panels are suitable for constructing driveable roofs subjected to heavy both static and dynamic loads.
For applications subjected to particularly heavy loads, STIFERITE Class BH and STIFERITE Class SH panels are available.
The thickness and reinforcement of the screed must be calculated according to the anticipated loads. STIFERITE panels have an elastic compressive strength exceeding 5,000 kg/m². For the STIFERITE Class BH and STIFERITE Class SH types, the elastic compressive strength is 7,000 kg/m².
