Description

The design-led variant of the aPerf® panel (formerly 'aPerf board colour'): an anthracite fleece core with a one-sided, through-dyed colour lamination for vivid wall and ceiling designs where acoustics become a visible part of the room concept. Mounted directly it damps broadband; with an air gap up to the highest absorption class A. Please note: with the coloured lamination the reaction-to-fire drops to class E (mechanically fixed on a mineral substrate). Where higher fire-protection requirements apply, the uncoated aPerf® panel (B-s1,d0) should be preferred. Broadband absorbers can optionally be built with aPerf® panel colour; the measured values then correspond to the aPerf® panel 25 mm / 3,000 g/m² variants. Minimum order 60 panels per colour; smaller quantities on request.
