Cavity closers

A cavity closer from H Jarvis which performs four separate functions and is vital in the creation of energy efficient new homes.

Diagram showing how the cavity closer acts as a template for the bricklayer, seals and insulates the cavity opening, provides a d.p.c. around the window reveal and acts as a simple fixing system for the finished glazed window.

H Jarvis cavity closers which are designed to maximise thermal efficiency and simplify window installation.

H Jarvis produces a range of cavity closers which allow finished glazed windows to be fitted at a later stage in the building process without disrupting traditional building practices and procedures. No special site skills are required.

Cavity closers are available to fit cavities of 50mm, 75mm and 100mm and they can be welded together to create a bay window former. These help builders create bay windows with ease as the cavity closer provides a clear footprint for them to work to.

Also available are cavity closers for door combination frames.
