Description

Sound-absorbing sandwich roof panel with a mineral-wool core and steel facings, the inner skin perforated. Significantly improves sound insulation and sound absorption. Designed primarily for ceiling applications, and in special cases also usable as an external roof (unheated rooms only, since there is no vapour barrier). Patented fleece dust-protection system.
