Doodlehime Posted October 5, 2020 Share Posted October 5, 2020 We want to install EWI on our house. The soffits are due to be replaced this week as part of a new roof. Next door has had EWI replaces already as part of a gov scheme and I noticed rockwool has been placed in the soffits. the EWI would when retrofitted come below the soffits but I assume this would leave a thermal bridge band of around 6-9 inches around the top of the wall in the affected external walls. Would it be advisable to use rockwool or PIR behind the soffits now before they are finished? Link to comment Share on other sites More sharing options...
