A third of all the heat lost in an un-insulated home is lost not through the windows, the roof or the floors but simply through the walls. Cavity wall insulation is a fantastic and effective way to significantly reduce the amount of energy you need to heat your home, resulting in around a £110 savings per year.
If your home was built from 1920 onwards, then chances are that its external walls are `cavity walls’ (this means that they are made of two layers with a small gap or `cavity’ between them.) Insulating your cavity walls is simply the process of filling that gap- with very good reason. Cavity walls are terrible for letting heat escape from the home. Insulation is an effective way to save energy and money at home, as well as providing a warmer, more ‘homely’ household.
As well as cutting costs, insulated walls also means using less energy, which reduces carbon dioxide emissions- one of the biggest causes of climate change. Another reason that cavity wall insulation should be considered is the idea that it can also help to reduce condensation inside the house. Condensation is often a big problem. Cavity wall insulation is so cost effective that it will pay for itself over and over again. The better insulated your home, the less energy you need to keep it warm resulting in lower heating bills.
If your home was built in the last 10 years it is likely that the cavity is already insulated. Some walls can also be unsuitable for cavity wall insulation. It is important to remember that if you’re thinking about cavity wall insulation, always check with a registered installer. He/she will then asses your home and see if it is suitable for insulation.read more
