Hello, im looking for advice on insulating my shed.
I have ordered some foil backed PIR boards and plywood sheets for the job.
I already have a breathable membrane on the inside face of the cladding. The thickness of my framing is 65mm and the thickness of my PIR boards is 40mm. Do I need to leave an air gap? And if so will a 25mm airgap between the cladding and insulation be sufficient and does this air gap need ventilating?
