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.Supplied 1200mm wide and pre-perforated for splitting into 2 × 600mm widths, it enables straightforward installation between standard studs or joists.With a manufactured density in excess of 10kg/m³, it also provides effective acoustic absorption while contributing to thermal resistance and fire safety. Classified Euroclass A1 non-combustible, it supports compliance in wall and floor systems.At 75mm thick, it is designed for medium-depth cavity constructions, providing substantial acoustic improvement and supplementary thermal performance.
