CAVITY WALL INSULATION & SOLID WALL INSULATION
Using Wall Insulation to reduce long term heating costs
There are only really two types of walls used in homes, cavity walls and solid walls. Cavity walls are two skins of brick or block, separated by an air gap of between 2 and 3 inches (50mm-75mm), whereas solid walls have no gap and are…………………solid.
The UK energy savings trust estimate savings of around £135:00 per year can be made from properly insulating your cavity wall, and savings of over £400:00 for solid walls. If you combine this with fitting double glazed windows then the savings long term can be substantial.
Both of these construction methods can benefit from insulation, of the 2 types, cavity wall is the simpler to undertake, consisting of injecting material into the cavity, such as foam or insulating beads.
This is done by drilling a series of holes in strategic places around the property and pumping the insulation into the gap via the holes and can generally be done in a day with the minimum of fuss.
This work should be undertaken by a professional, it is advisable to use CIGA, BBA or NIA approved cavity wall insulation installers.
Solid wall insulation is more labour intense and uses 2 completely different methods.
The first of these options is where insulating boards are fitted to the interior of the property – potentially reducing the area of the room because the boards are 2 -3 inches thick – it will also cause some disturbance if the work is being done whilst you are occupying the place at the same time.
The second method of solid wall insulation is to fit it to the exterior of the property, by adding a layer of insulating material – normally 2 to 4 inches thick and then applying a render coat to the new surface as protective cladding.
Again, this is not a DIY job and should be undertaken by professionals.
