Hi All,
Looking for some ideas on insulating a Skillion roof on a shed for maximum R value, the roof is constructed with 200mm C purlins, 40mm top hat and 22mm ceiling battens.
I know that the recommended procedure is to put on Anticon above the top hats and let it sag down from the Colourbond sheet but WHY not stretch it over the C Purlins and fix it under the top hat?? am I missing something here?, it would look a lot better, whats the catch?.
My thought would be from top, Roof sheet, Anticon, 25mm gap, Batts, and then gyproc, any body got any other suggestions?
TIA
Colin
