An A1 Non-Combustible Glass Mineral Wool roll, manufactured using Knauf Insulation’s unique ECOSE® Technology, and designed specifically for use in timber frame applications between studwork. Designed to friction fit between timber studs, which prevents air movement and infiltration through or around the insulation, minimising heat loss. Ready-cut to allow quick and simple installation, maximising on-site efficiency when compared with alternative insulants. Rolls are fully cut into 2x570mm and 3x380mm to suit commonly used timber stud spacing.
