I'm trying to insulate a very old shed - timber framed, and a mix of corrugated metal and timber cladding (three timber walls, roof and fourth wall metal)
Foilboard looks like the way to go, which I was going to attach to the studs, creating an air gap between the board and the outside wall. I may or may not line the shed with ply or plasterboard later.
Do I go shiny side outside (which send logical to reject the heat outwards) or inside (which I've seen recommended, but seems counter intuitive) ?
Have I got the air gap in the right place?
a) Outside wall - air gap - foilboard - ply
Or
b) outside wall - foilboard - air gap - ply
Or
c) outside wall - air - foilboard - air - ply
It
I'm in SE Queensland so keeping the heat out, not in...
Cheers
Hello @jonmwilson
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about insulating your old shed.
When installing onto a wall the foil side faces towards the wall. Here is the link to the installation instructions for foil board, it includes the instructions for wall and roof installation. Typically, the air gap is placed between the wall and the foil board by using Foilboard Spacer Blocks.
Here is a link to our best advice: How do you add insulation to a garage or shed?

Just a friendly note to our New Zealand members the use of foil insulation products is prohibited
