Cavity closers are a very small but crucial part of the construction of a new house.
When building a house, the very best materials are used and the very best features are built in to ensure the end result is a well constructed, warm and dry house. Cavity Closers are part of this as they enable heat to be retained and not allowed to escape through the windows, and they also work as an effective window template for windows to be fitted at a later date.
Cavity closers are made of uPVC, a very strong and durable material.
When building a home, the best way to proceed is to fit Cavity Closers where the windows and doors are going to be fitted. Not only does this provide a visual template for windows, it also blocks off the cavity allowing easy installation of the windows and doors at a later date. The closer also provides further insulation and prevents warm air escaping in winter and stops the sun from penetrating and heating up the home in the winter.
There are different types of cavity closers. Some are designed with an additional layer of insulation that is for going that extra mile in terms of efficiency. Others are made with a thin layer of aluminum coating that is designed to prevent the rapid spread of fire. There is also a type of cavity closer available that is designed to be fitted after the building work has been completed.
If your house is being constructed by a reputable firm then Cavity Closers are likely to be included as standard. It is always a good idea to double check however as they are so important. Being made of uPVC they will last you a lifetime too so you never need to worry about replacing them or them eroding.
