Earthwool Soffit Linerboard

Product Code



Soffit Liner board is a faced high-density Earthwool® board that is suitable for the thermal and acoustic insulation of building soffits. The board is bonded with ECOSE® Technology, a revolutionary binder based on rapidly renewable materials instead of petro-based chemicals. Soffit Liner board with ECOSE® Technology is specifically designed as a thermal and acoustic material for the treatment of concrete soffits in commercial buildings. There are a range of facings to suit specific applications, and to offer an optimum combination of efficient sound absorption and low thermal conductivity. The insulation is less dusty and easy to cut. The rigid board provides an excellent finish and requires less fixings, which makes installation fast.
