I'm thinking of having a custom workshop/shed built, 14Ft x 9Ft.
The shed will be built with 3" x 2" framing with an apex roof. I will be dealing with the insulation myself.
Which is the best method for this? fibreglass or polystyrene between the framing and either plywood or un-skimmed plasterboard for the walls?
The finished interior will have an emulsion paint finish.
I suppose plywood would provide a better finish (no taped joints) but plasterboard would be cheaper and easier to install.
Suggestions and opinions please.
PS
In an earlier thread someone mentioned insulating flooring from Costco can anyone elaborate?
