Sound-absorbing sandwich roof panel

Description

Sound-absorbing sandwich roof panel with mineral-wool core and perforated inner skin. 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.
