Most modern homes are built with cavity walls, which are made from two layers with a gap in between, however many homes in the UK, especially those built before 1920, were built with solid walls.
You can often work out what type of walls you have by the external brickwork on your home. If your home has cavity walls, the brickwork will usually have a regular pattern, all laid lengthways. However, if your home has solid walls, you will usually see an alternating pattern on the brickwork where bricks are laid lengthways then widthways then lengthways and so on.
This alternating brickwork is because, unlike cavity walls, solid wall homes do not have a gap in between layers. This results in substantial heat loss and low energy efficiency for the home. It has been estimated by the Energy Saving Trust that solid wall homes lose twice as much heat through the walls as cavity wall homes, so investing in solid wall insulation to prevent this can soon pay for itself in the savings that you make, estimated to be as much as £460 annually.
You can insulate your solid wall home either from the inside or the outside, but internal wall insulation is often seen as the most preferable option for homeowners as it is generally cheaper.
At British Gypsum we offer four internal wall insulation solutions, all of which are available under ECO schemes, so if you’d like to find out more about our products and how they could benefit you, please see our internal wall insulation page.
Internal wall insulation (IWI) is a type of solid wall insulation that is recognised as one of the most energy efficient home improvements that can be made. For this reason, internal wall insulation is often available to consumers under ECO or other government funding schemes.
One of the main benefits of IWI for the consumer is that it helps the inside of their home to heat up quickly and retain the heat for longer, but in addition to this there are many other benefits, including:
- A reduction in heat loss through walls
- A reduction in CO2 emissions from the property
- A reduction in energy bills by as much as £460 per annum
Installing IWI requires no planning permission or scaffolding and preserves the external appearance and facade of the building. The installation of IWI can also take place when other interior work is happening or if the building has boundaries.
