I've just moved in to a new workshop and I clearly have a spot of 'renovation' to do. The building ( aka shed ) is 40' x40', of wooden construction on a concrete floor, corrugated aluminium sloping roof. The south wall is fitted with lapped planks - half of the wall is lined externally with 1/2" ply, the rest is just lapped planks - there's a 7'x4' window in it. The west wall is just 3/4" compressed chipboard, but the roof extends over it to form an open shed. The east wall is 1/2"ply, lined internally with thin fibreboard - and the north wall is compressed chipboard again, with the roof extending over it.
My main priority is keeping moisture out - condensation is a big problem at the moment, especially with the roof.
I intend to remove the lapped planks on the south wall and make good with 1/2" exterior ply before replacing the planks, and lining the interior with 1/2"ply. Building on the existing frame will leave a 3" air gap between the boards. The east wall, also framed, will get the same treatment internally. The west wall I hoped I could get away with simply cladding over with
1/2"ply - and the north wall will have to be lined externally as there's no access to in internally.
As regards the roof, I've sealed up the holes where the rainwater was getting in, but it obviously needs boxing in and insulating.
Any comments, suggestions?
