Polycarbonate vs Glass


VS Glass

Glass is one of the best-known materials. Like polycarbonate, plexiglass/PMMA and fiberglass, glass is also transparent thanks to a transparency coefficient between 0.80 and 0.90. if used for roofing, it is usually subjected to a thermal tempering process to resist shocks and be safe. In this way, if an impact occurs, fragments are prevented from crumbling and risking injury to the user. Unlike plastic materials, when glass plates get hit, they shatter into small sharp parts, forming a concentric spiderweb.


Glass is less resistant than plastic materials, which means that it’s easier to break during installation. It bears only 10 Joules of load, has a mechanical resistance of around 170 N/ mm² (for 4-mm thickness) and, considering its intrinsic weight, requires strong anchoring in suspended constructions such as shelters.

Among the many materials on the market, glass is currently not recommended when building shelters of self-supporting structures.
