Reveals, cold bridging and the perimeter detail in Sidmouth
The junction between opening and wall is where a lot of performance is won or lost. An uninsulated perimeter gap forms a cold bridge, and the cold surface it creates at the reveal is where mould appears first.
Correct detailing fills that gap with insulation and closes it with an airtight layer on the warm side and a weather-resistant layer on the cold side. Expanding foam alone does part of the job and is routinely mistaken for all of it.
The clue is location. Discolouration concentrated at reveals and corners rather than spread across the surface points at the perimeter detail rather than at the glazing.
