ET/MCC/100
Expanded (EPS) polystyrene cavity closers, designed for closing cavities around openings in masonry, timber frame and steel frame wall constructions.
Cavity closers are fitted within the cavity wall around doors and/or windows. By forming a seal within the aperture, they protect against water ingress and condensation, also acting as an effective DPC barrier and preventing thermal bridging.
