As noted in the chart below created from rs means data if you compare the life cycle costs of a sarnafil roof estimated to last 35 years versus a tpo roof lasting 20 years pvc is the less expensive choice.
There must be an adequate void minimum 50mm between the deck and the insulation traditionally mineral wool to allow free movement of air and to prevent moisture vapour being transmitted from the building outwards where it could condensate in the roof.

It is suitable for use in most mechanically fastened systems using both sarnafil pvc and fpo membranes.
In a cold roof construction the sarnafil membrane is installed directly to the structural decking usually timber with firrings to fall.
Sarnavap 1000e is manufactured from low density polyethylene blended to produce a vapour control layer that is flexible when cold resistant to chemicals and ageing and rot proof.
Pvc s are documented to last longer than tpo membranes who are still experiencing premature failures.
