Hassle free cavity formers available

Our cavity formers provide a benefit in their quick lead time from order to delivery, enabling openings to be quickly and accurately formed on site, allowing the scheduling of external joinery to be taken off the critical path. Windows and doors can be ordered in plenty of time, knowing that they will fit accurately into the pre-formed openings. No need to wait for the openings to be built, then measured and ordered, potentially saving you weeks on site! 

The standard cavity closer order process is incredibly easy. Just specify the cavity size and whether it is ‘in-line’ (brick and block lining through) or ‘in-check’ (set behind the face brickwork). 

Fire rated cavity closers are also available, combining a 60 minute cavity fire barrier and cavity closer former in ONE product.
