Hello
I am looking for some advice on insulation.
Building an insulated wooden office (walls/floor and roof) in an uninsulated garage. I am looking to find the solution for the best insulation but I am tight on space.
I have two thoughts at the moment for construction of walls, floor and roof.
Option 1
100mm insulation (probably foil backed PIR) in 100mm stud work
Standard vapour control layer onto stud work
Standard plasterboard/plywood for floor
Option 2
80mm insulation (probably foil backed PIR) in 100mm stud work
Foil vapour control layer onto stud work. This leaves 20mm min air space and reduces cold bridging on stud work.
Standard plasterboard/plywood for floor
My question is what would give me the best insulation for the room? I like the idea of the 20mm space to help with electric cables on option 2.
Any other ideas are also appreciated.
Thanks
