The insulation we usually recommend
Loft insulation
Mineral wool laid between and across the joists to 270–300 mm so heat stays in the rooms below.
Cavity wall insulation
A borescope survey, then blown mineral wool or bonded bead injected into empty cavity walls.
Internal wall insulation (IWI)
Insulated plasterboard or stud systems fitted inside solid walls where the outside must not change.
External wall insulation (EWI)
A complete certified build-up of insulation board, mesh and render from one system holder.
Draught-proofing
Sealing doors, windows, letterboxes, hatches, floorboards and unused chimneys — every home's quick win.
