Cavitybatt Insulation
Cavitybatt is a specialized wall insulation designed to improve indoor comfort through better temperature control and noise reduction. It’s commonly used in modern residential and commercial wall systems, where consistent insulation performance is needed inside drywall, timber frame or steel frame structures.
What Is Cavitybatt?
Cavitybatt is a precision-cut glasswool slab with a rigid, glass-tissue facing that helps it stay firmly in place inside wall cavities. It absorbs sound, slows heat transfer and adds an extra layer of fire safety, making it ideal for internal walls that need reliable and long-lasting insulation performance.
Which Thickness Should You Choose?
51mm Cavitybatt – best for light acoustic absorption and basic thermal insulation.
63mm Cavitybatt – a mid-range choice with stronger sound control and better performance.
102mm Cavitybatt – top-performing thickness for maximum acoustic reduction.
