Requirements and Classifications

For a noise barrier, the following properties are generally required:

Light transmission of at least 80% for transparent panels. Light transmission decreases per thickness, at 15mm, light transmission is 80.5% for clear sheets
Flame retardant properties. The 8mm Vitroflex PC has been tested to the EN 1794-2 Brush Wood Fire Test and has been rated Class 2. This rating is also valid for 10, 12 and 15mm.
Impact resistance according to EN 1794-2. Vitroflex PC 12 mm obtained the highest class for risk of falling fragments, 6C according to EN 1794-2 Annex C (400 kg of impact on the hard body). This classification is also valid for 15 mm.
Sound reduction values of Vitroflex PC products. The values are valid for all types of Vitroflex PC solid sheets.

Thickness 8 mm 10 mm 12 mm 15 mm
ZTV Lsw 88 25dB 26 dB 29 dB 31 dB
