A cavity closer has many functions. Made from a strip of material – usually plastic – the cavity closer is placed within a cavity wall to provide insulation. Fitting cavity closers within a building also creates a seal, preventing water or damp entering the cavity wall and the interior of the building itself. Why do you need a cavity closer? Building regulations specify that any building must resist contaminants and moisture; installing cavity closers can help protect any water or dampness from entering through the walls. It is also a requirement to conserve fuel and power. Closer insulation can help ensure this standard is met.
