This high-performance film offers protection in the event of a bomb explosion at very high constructional danger zones, e.g. in cases of high and narrow construction or at especially endangered entrance areas. Additionally, the multi-ply quality of Profilon ER1 generates an excellent impact resistance, which is an important additional feature for endangered parts of a building.

Profilon ER1 provides extremely high explosion resistance, impact resistance, splinter retention, reduction of the spreading of fire (no fuming) and UV absorbing. Profilon ER1 was tested in a shock tube with a reflected pressure wave. These repeating shock waves alternately produce firm pressure and suction. In doing so, an explosion in a narrow and high construction is simulated, where the shock waves are reflected by the surrounding buildings.

Which resistance class does Profilon ER1 achieve?
Profilon ER1 is a multi-ply film laminate with a strength of 475μ. Though the coating with Profilon ER1 single and insulation glass achieves impact resistant properties of laminated security glass. The coated glass achieves the following resistance classes:

• explosion resistance tested in stock tube according to DIN EN 13541 ER1 (NS)
• impact resistance (steel ball drop test): - A1 according to DIN 52 290 - P2A according to EN 356 and UL 972

There are two variants of Profilon ER1 available: Transparent and solar (sun protection)
