Applying the finishing touches to this project in Sandown, Grange Heights, in Grange. We have carried out full external wall insulation works to these two 3-bed semi detached homes. With this technique you get a layer of insulation, a sort of blanket effect, to the entire house on the outside. The advantages are many as your house doesn’s experience any loss in space on the inside, there’s no decoration on the outside, and the process helps keep your home warm in the winter and comfortably cool in the summer.
