January 19, 20242 yr Hi all, My name is Joe and I'm a carpenter in the process of the complete renovation of an 1920s end of terrace. Plans are to insulate, extend to the rear and loft convert.. since the house has been completely gutted I think now will be the best time! Have joined the forum as I have many questions... 😂
January 19, 20242 yr Welcome As it is gutted, now is the very best time to deal with the air leakage.
January 19, 20242 yr Author Thanks guys! It sure is leaky at the moment haha! The House still has the original slate roof without membrane, unfilled wall cavities without closers at eaves/window openings... single glazing.
January 19, 20242 yr Don't fall into the trap of just making the inside airtight. You need to stop air bypassing the insulation. Then worry about ventilation, MVHR is best and easy to fit when the place is empty.
January 27, 20242 yr Author Thanks for the advice! MVHR is something I will need to do some reading up on.
