Azila Posted June 30, 2005 Share Posted June 30, 2005 Help,We have received our devis for fixing our roof but our roofer has thrown me by writing the following:- "Fourniture et pose de 69m d'airflex en isolation" the thing I do not understand is the airflex bit, is this the brand name for the waterproof material that goes under the tiles because he has also written on the next line "pose de 69m de sous toiture 262,97euro" and I cannot work out what this is at all.Thanks Azila Link to comment Share on other sites More sharing options...
Anton Redman Posted June 30, 2005 Share Posted June 30, 2005 It is I believe thermal insulation rather than just a vapour membrane and is a good way of doing the jobs. Knowing what I know now I would have used it despite price premium on our roof. Link below to manufacturers website which has lots of useful stuff including how it is used.http://www.kdb-isolation.com/ Link to comment Share on other sites More sharing options...
LesFlamands Posted June 30, 2005 Share Posted June 30, 2005 Airflex is a brand name for a reflective foil insulation product. I think he must be suggesting this in place of roofing felt (ecran sous toiture) which would be the 262.97 euros. Airflex ia about 11 euros per square metre so 69 square metres would be around 760 euros. Link to comment Share on other sites More sharing options...
Azila Posted June 30, 2005 Author Share Posted June 30, 2005 Hi Anton & CharlesThanks for the quick reply. If my roofer uses this airflex material does it mean I don't need a waterproof felt as he has give me a price of 1209.68euro just for the airflex. I don't mind paying the extra as long as I know the roof is watertight and insulated. Sorry to ask more of you but I'm sure when we talked to the roofer he showed us two different types of material but of course when you get back here you remember differrently.Thanks Azila Link to comment Share on other sites More sharing options...
Anton Redman Posted June 30, 2005 Share Posted June 30, 2005 I think Charles knows more than me about this but Euros 500 extra for installed thermal insulation seems good value to me when you look at French TVA, Social Security and labour rates.

VJ Posted July 18, 2005 Share Posted July 18, 2005 Hi I dont know if you received all the information you needed for your roof? but yes the Airflex is a insulation material that if the roof is being re tiled/slated then it goes on with counter battens onto the roofThe insulation should enable the roof to breath as well as keep it cool in summer by reflection and warm in Winterby insulationAfter the insulation working out to the outside the boards come next (Vollege)which have a air gap between them and the insulation allowing air flowI beleive it is a good idea to put felt or tyvek next as if a slate or tile comes off the boards stay dry and finally the slates /tiles The above is dependant on the roofing types in your area but in the main they are just variations Remember if you do it right now then there are no worries when it is January cold and tipping it down Hope this helps VJ Link to comment Share on other sites More sharing options...
