PVB guarantees a high resistance and a better post-brake behavioural.
These are exactly the needs structural building safety facades and coverings glass must satisfy.
Post-breaking behavior
- In applications of structural glass with PVB in coverage stratification provides greater safety in case of breakage of the slabs.
- The type of back glass processing is also essential for safety.
In the images is it possible to notice the comparison between the post-breakage behavior of both plates in case of glasses tempered/tempered and front glass tempered and rear hardened.
Tempered/tempered glass can come out from the frames and fall, while Tempered/Hardened glass remains in place.
For this reason EnergyGlass photovoltaic glasses are made by tempered/hardened glasses.
Tests carried out at the Stazione Sperimentale del Vetro di Mestre
