Description

Waffel is an acoustic panel made of Basotect, a fibre-free melamine resin foam, with a waffle structure on one face for direct bonding to ceilings and walls. Alongside the standard version, the range includes the more finely structured Waffel Mini and the water- and oil-repellent Waffel H. The panel is intended for surfaces where low weight and a shallow build-up are required, for example in production facilities and recording studios.
