I am using insulation boards which have foil on one side.
which way should the foil face? facing into my room or facing out?
I am using the insulation boards directly onto the walls of my trailer.
The walls of trailer consist of outer aluminium skin, rockwool (i presume) insulation inside and a 3mm plywood sheet to enclose.
this is not warm!
I have bought sheets of insulation board and am attaching directly onto wall with no gap and then boarding over with hardboard.
Does the foil side need to be against the existing wall or the hardboard side facing into the room.
Do i need an air gap between wall and insulation board?
I have no damp on the walls.
any advice would be great.
thanks
