25mm Knauf Acoustic (APR) Insulation Roll (26.64m2/Roll)

Glass mineral wool loft insulation roll using ECOSE® Technology and a high recycled content. Sized for friction fitting between timber and metal studs at 600mm centres, it reduces airborne sound transmission in separating walls, intermediate floors, and internal partitions.With a manufactured density in excess of 10 kg/m³, it delivers reliable acoustic absorption while also contributing to thermal resistance and fire safety. Classified Euroclass A1 non-combustible, it can be used within wall and floor systems to support compliance with fire and acoustic standards.At 25mm thick, it is best suited to shallow cavity constructions where space is limited and only modest acoustic improvement is required.
