Why Do I Need Cavity Closers?

Cavity closers are the best way to ensure that the window and door openings on your project are pulling their weight when it comes to securing the thermal energy requirements of a new build or refurbishment.

The Part L Regulations will require a photograph of the cavity closers in place submitted on completion for sign-off by the local Building Control Office.

Top Tip:

If the windows and doors are being built-in as the masonry progresses then the cavity closers can be tacked directly to the frames before they are set in the wall.

Are 100mm Cavity Closers Expensive?

Cavity wall closers are not expensive, and the YBS closer that Wade can supply is designed to fit several different cavity sizes and masonry profiles. The rigid plastic casing is easy to cut and fit and provides continuous thermal resistance when installed correctly.

Simply cut the 100mm cavity closer to length. You only need to cut the insulation to width to ensure it will fill the cavity. Cavity closers can be joined if sealed with tape to ensure as little as possible is wasted.

Top Tip:

Cut the vertical cavity closers to run past the horizontal closer below the cill. This will allow any moisture to drain and stop it from collecting below the door or window cill.

How Many 100mm Cavity Closers Do I Need?

Cavity wall closers are only required where you don’t have something else closing the gap such as a cavity wall lintel. A cavity wall lintel that is insulated, or thermally broken, will be sufficient to close the cavity overhead.

Cavity closers come in standard lengths of 2.4m, which means that for a standard window of 1000mm width by 1050mm height, you will need two lengths. For a standard door opening that is 2.1m high, three will be required.

For wider cavities, take a look at our 150mm cavity wall closer option from YBS.

Top Tip:

When jointing cavity closers, cut the join at a 45° angle so that any moisture is directed to the exterior.
