I own a couple of small commercial buildings and want to refurbish one of them to then use simply as dry secure warehousing.

It's a 50 year old single brick, three unit building (joined by single doors) with concrete asbestos roofing mounted onto concrete trusses etc. We've stripped the guts out and it's in pretty good shape, all be it dirty and dusty. It was used as a car repair/spray shop so the flooring is pretty crap, lots of oil etc and we are going to jet wash that with detergent.

Once the roof is on we intend to fit suspended flooring throughout to make it straight and level, line and plaster board the walls. The roofing will be changed to 80mm insulated composite panels with rooflights - the concrete trusses etc are fine and in good condition and will accept a new roof and have been surveyed by a roofing company.

Having spoken to the council, they don't require building regs or planning permission - it is already B1 and we are not planning to use a permanent heating solution and so they have said crack on with it and enjoy (makes a change!)

My question is that we intend to line the walls and as it's single skinned I need to have breathable membrane against the single brick wall so we don't have a moisture problem - so what should I use?

Many thanks

Wouldn't you paint the inside of the bricks with tar or something, and then fill the cavity with polystyrene?

I'd be looking at using a composite plasterboard with integral vapour check and fixing it to the brickwork on metal studs to create a cavity.

Something like Thermaline http://www.british-gypsum.com/products/plasterboar... which is a sheet of plasterboard, with a bonded sheet of insulation on the back of it. The insulation provides the vapour control.

Then tape and joint as normal.

If you need any more info, or budget costs let me know. (Or if you want it doing wink)

Thanks guys wink

Would something like Tyvek in between the wooden uprights and wall also be a possible solution?

I've got a 1200sq ft building to clad and am thinking about a costs currently as I want to spend the right money but not too much...

I've had this product fitted into 2 properties I own, absolutely great, big savings on heating bills as well if you do the whole building
