All about glass > Break-in resistant glass

Our Break-in resistant Plastofloat is tested and rated according to European standard EN 356 specifications by the CNPP in its own laboratory , from 6(P6B) to 8(P8B).

If three samples of a special composition of Plastofloat can receive at least 31 impacts total (including at least 12 blows with a sledgehammer), and hatchet blows and if these blows do not make a hole of at least 40 cm on a side, the laminated glass is assigned a resistance level defined by the number of blows:
 

Break-in resistance class	Number of impacts
6 = P6B	30 à 50
7 = P7B	51 à 70
8 = P8B	at least 71
