The composite structure of SkyRainbow® results in an impressive strength-to-weight ratio, even when comparing large panel sizes. Despite its low weight, which makes Sky Rainbow ® easy to transport and handle in the factory and on site, its rigidity and high strength make the panels keep their shape and remain flat, even when exposed to extreme temperature changes.

Comparison of thickness and weight of panels with equal rigidity
