Warm roofs, loft top-ups & multifoil systems
About a quarter of the heat in a typical Hampshire home disappears through the roof. Loft insulation is the cheapest fix per pound you will ever make to a house — as long as the depth, the material and the ventilation are right.
Traditional mineral wool works, but at the 300mm depth now required it swallows the loft floor and makes storage impossible. Modern multifoil and Superglass systems retain a comparable amount of heat in a fraction of the thickness, so you keep usable loft space, and they can be fitted at rafter level to create a genuine warm roof rather than a freezing cold one.
We survey the loft first: what is already up there, whether it is compressed or damp, how the eaves ventilate and whether there are cold bridges at the hatch and around downlights. Then you get one clear recommendation and a fixed price. Old, sagging fibreglass can be lifted and removed as part of the job.
