Internal wall insulation for cold, solid-wall rooms
Wall Insulation Basingstoke
If one room in the house is always colder than the rest, the wall is usually the reason. Wall insulation in Basingstoke is most often about solid-brick walls, single-skin extensions and rooms built over an open garage — none of which can be filled from the outside.
How we approach it
Where there is no cavity to inject, the answer is an internal insulation build-up: an insulated board or a studded system with dense insulation behind it, taped and skimmed so the wall finishes flat and ready to decorate. The detailing matters more than the product — reveals, lintels, floor and ceiling junctions all have to be carried through, or the cold simply reappears as a stripe of mould at the edge.
We survey before quoting so you know exactly how much room you lose, how the sockets and radiators are handled, and what the wall will feel like afterwards. Everything is fitted by our own teams, at a fixed price, and guaranteed.
