AAaaaaahh.
Can anyone give me a definitive answer on ventilating the Decra product.
Breathable membrane (possibly with a breathable board under this) Insulation between the rafters and lined with ply or OSB as a VCL. Happy to stick a VCL plastic in but don't think it needs it. Will be sticking a little heat into the workshop but it will be occasional.
Problem is that there are a couple of ridge vent options as well as over the eaves type available, Do I need both either or none?
Have spoken to Decra technical but the lady was friendly but not very helpful.
