So it seems I have missed the fine detail on my vehicle garage doors. Brickies have constructed the reveal with a cavity and closed it by returning block with insulation strip and dpc in the same manner as a window. The other day I was gazing in thought at the house and realised the sectional garage doors will be fixed internally to the inside blockwork skin. What then would I do with the reveal:-
- leave as is and plaster over to internal skin (door face) with the dpc in place. Would dpc still be effective?
- remove insulation and dpc and close cavity completely with block, what then do I do for dpc to stop damp spread internally with a 215 mm internal leaf.
Some pics to help hopefully.
Thanks in advance.
