Cavity batts Insulation by Superglass is a non-combustible, British Board of Agrément (BBA) approved glass wool insulation product for use in masonry cavity walls. It provides excellent thermal insulation in full-fill or partial-fill external masonry cavity walls up to 25m in height for full-fill and with no height restriction in partial-fill.

The cavity wall insulation is manufactured from nearly 84% recycled glass and is supplied at 455mm wide to allow easy installation between standard vertical wall tie spacings and minimum on-site cutting and waste. The glass mineral wool cavity batts do not degrade with time, rot or support the growth of moulds or vermin. The wool insulation allows vapour to pass freely and does not let moisture reach the inner brick of the wall insulation.
