Not a planning matter, But I was hoping someone could help me.
An engineer I have recieved drawings off has specified Polyurethane, foil backed both sides for the cavity wall insulation. However I cannot find this insulation. I have found Polyurethane rigid board but It isnt foil backed. Is there any such thing? And if there is, can someone post a link so that I can find it.
Cheers

http://www.insulation.kingspan.com/ireland/k8.htmi realise one is phenoloic and the other is polyisocyranute…. but both have similar performance to polyurethane.

Some Phenolic insulations were taken off the market because of HCFC’s, they remain in some catalogues and have very impressive thermal resistance, but are not available on the market. Can anyone clarify?
