Default Re: Lining a Metal Shed

Why bother with wooden battens - you can attach Celotex to the metal panels inbetween the tubing using one of the modern "no more nails" types of adhesive or foam-in-a-can as used by window installers. Much quicker and no wood to rot.

Celotex/kingspan comes with its own vapour-barrier; fill the gaps between the edges of the Celotex with more expanding foam to stop 'indoor' damp getting in to the edges. Then panel over the lot with thin ply, and paint white to make it look nice.

You need to get some sort of 'fillet fillers' between the roof-corrugations and the walls to exclude the local rats/squirrels. Don't make things totally airtight though, or mould can become a hazard - your boat ventilators sound a good idea.
