Rockwool Multiboard
Product DescriptionRockwool Multiboard is a strong and rigid board. ApplicationsRockwool Multiboard can be used for the thermal and acoustic insulation of horizontal and vertical walls where a stable insulation product is required. For example, tank walls or acoustic panels. Advantages• Excellent thermal and acoustic insulation
• Rigid product combined with aluminium foil or fibreglass coating provides a smart, smooth surface finish
