What are cavity closers?

Cavity closers are insulation materials used between windows to keep in the heat and to fill gaps. They are a form of insulation that builds an envelope to trap the heat from thermal bridging. They are commonly installed between windows and doors. They can easily protect you from unwanted elements from the outside environment. Gaps surrounding your windows and doors are very much responsible for the environment within your homes, and that is why one must make sure that cavity closers are installed to protect against thermal bridging.

What are cavity closers?

What is Thermal Bridging?

Thermal bridging is a major contributor to heat loss. This occurs when two exposed thermal elements meet resulting in the heat escaping from the building. These Closers are very effective in closing windows and door reveals, as they do not let the heat pass through. Cavity closers are great insulators for improving resistance against heat loss even when your walls and attics have thermal insulation. There are traditional ways of thermal bridging and cavity closing that one can follow for optimum results.
