The walls are quite cold, and I think are damp. Insulation is required. what insulation is more suitable/appropriate (rockwool? celatex? any other?) is one better than another? Is there an optimum time of year for it to be installed? (summer?) or does it not matter? presumably it has be dry weather?

Cavity wall insulation removal
Anonymous user 22/06/2026 - 7.50 AM
I have CWI which i am pretty sure has failed. Do companies come out & do inspections to check or is it something i could do myself. I'm assuming it's just a matter of drilling a hole into the cavity & putting a camera through, or would using a camera that shows up any heat loss be better. Is CWI better nowadays than it used to be? Many thanks
