Insulation

External insulation advice (to cure condensation in back bedroom)

Anonymous user 28/02/2024 - 3.04 PM

Can someone with hands on experience explain how external insulation should be installed. I have had several problems with condensation in a back bedroom (solid brick wall) over the years and want to make sure this attempt to cure it will be the last. I wanted to know how the insulation boards need to be fixed to the wall, and do they need to cover the dpc? Should there be a gap between the boards and the existing wall, ie creating a cavity? Should the boards be fixed with adhesive or something else. Do I need a timber frame to hold it all in place? Once affixed Ive assume that a metal mesh and standard render is adequate, is cladding any better? Many thanks
