Thanks to noseall's advice I've built the structure and deck of my extension roof, and am now ready to add the insulation/EDPM
From checking the forums PU adhesive seems the way to go. I've got a 18mm OSB deck and so am plannning polythenene VCL next, then 130mm Celotex, then 9mm OSB, then the rubber.
Do I bond the VCL to the OSB with PU adhesive, then bond the Celotex to the VCL, then bond the OSB to the Celotex? I'm a bit concerned that bonding the insulation to the polythene vcl won't be very strong.
Is the XR4000 celotex okay as it is the cheapest?
Is any PU adhesive okay like this one?
