Hi all
I've rebuilding a lean-to on the side of my house. It measures 2500mm x 900mm. It has concrete base, 3x2 walls,15mm external cladding, osb roof with rubber covering. Here are photos so far
We are going to put the washing machine and tumble drier in it and I would like to insulate it. I have some 8mm timber t&g to cover the insulation.
It won't have direct heating but will receive heat (and humidity) from the tumble drier and some heat will enter from the kitchen through the cat flap.
Do I need a breathable membrane behind the insulation?
Do I need a vapour barrier in front of the insulation?
Any other considerations I should be thinking about?
thanks!
