gingerbeer Posted January 5, 2012 Share Posted January 5, 2012 I certainly do not claim to be an expert. Check very carefully the R ratings. My understanding is that aircell products have a very good rating at keeping heat out in the summer, but not so good at keeping heat in during the winter. Fibreglass batts have there own problem in that the rating drops over time, as the material shrinks away from perimeter members. Steve Link to comment Share on other sites More sharing options...
malrift Posted January 5, 2012 Share Posted January 5, 2012 i still reckon polystyrene is one of the best and cheapest. Link to comment Share on other sites More sharing options...

Cichlabxr Posted January 5, 2012 Share Posted January 5, 2012 The r Rating of Aircell is 2.5. I live out near Richmond where it gets pretty hot at times lol . We were advised to insulate our roof to 3.5 or 4. The main problem you could have with aircell is the condensation. Metal rooves without an air space and/or a vapour proof barrier are susceptible. Insulco makes a product called Vapa Chek well some name close to that. Also roofing blankets nearly all come with a foil side tp prevent the condensation problem.

gingerbeer Posted January 5, 2012 Share Posted January 5, 2012 I have seen a product that had polystrene with a silver blanket outside nailed to the outside of the frame that looked good and made sense. Not sure what the trade name is but.... Link to comment Share on other sites More sharing options...
Noddy65 Posted January 7, 2012 Author Share Posted January 7, 2012 Hi Gingerbeer...sounds like Foilboard...it also sounds like it might do the trick as the R rating is 3 -4 depending on thickness Link to comment Share on other sites More sharing options...
