Hi,
Recently moved house into a 1900's house (Semi). And the main gable wall needs to be insulated. There is also a slight bowing to the wall, this had been checked by a structural engineer prior to purchase and no issues has not moved in over 70 years. And he was perfectly happy to sign it off for mortgage etc. So the wall in no level there is about 3" in the centre to the two sides. This wall is 7m long.
So options are
1) Full stud wall (3"x2" treated) with top and bottom plates, PIR insulation inside the studs, taped, vapour barrier and then plasterboard
2) Batten the wall (treated 2x2) fit 50mm PIR in the gap, then flip PIR vertical so it's now 100mm and then plasterboard
Option 1 would leave a small gap in the centre as the stud would be level, how would you fill this?
Option 2 would leave the curve
Or if anyone has any other ideas or advice it would be most welcome
Thanks
