(i realise that is not a cheap thing any thoughts will be most welcome.....thank you ETA......OK i think i cant post the link to the photo as it belongs to the estate agent. so i can only say that it is a roof with a central gable that has no more than about 15 degree slope and is like the roofs of those metal garden sheds. any help is appreciated Re: near flat roofs.........insulation of..sorry cant find a 2Aug 05, 2011 12:18 am Do you mean the roof is timber or the ceiling lining is timber??
In near flat roofs or cathedral ceilings you can use foilboard. If you replace the roof it will sit directly under the new roof. Otherwise, it will fit between battens above the ceiling lining. It is possible to replace a ceiling. The cost will depend on whether you are just replacing the cladding, or changing the cladding (ie. going from tiles to colorbond), and therefore requiring support structural changes Re: near flat roofs.........insulation of..sorry cant find a 3Aug 05, 2011 11:17 am It is difficult to retrofit insulation into near-flat roofs. You'll either have to take down the ceiling plasterboard or lift off the roof - the former probably easier and cheaper. You can take off portions of the ceiling plasterboard and put in concertina foil between the rafters, they are good for keeping heat out because they are reflective. Concertina foil is also very cost effective. Bulk insulation is better for keeping heat in, but only truly effective in combination with foil. I have near-flat roofs too but I have to put in all new roofing. So I am doing foil (glareshield) over the battens, then two layers of foilboard - one between the rafters, and one under. If you want to spend the time to take down all the plasterboard, putting foilbard up then putting the plasterboard attached to that is a good way to go. Here are my roof details Newtown rebuild: https://forum.homeone.com.au/viewtopic.php?f=53&t=48977 Re: near flat roofs.........insulation of..sorry cant find a 4Aug 05, 2011 5:39 pm I have a 5-8 degree pitch on my new roof but put in sarking before the roof went on and insulation in before the ceilings went up. Have done this in the build because of the difficult access issues post build. Might be easier to lift the old roof for insulation installation.

Otherwise it will be like shooting blindly and hoping it will hit the target. Re: near flat roofs.........insulation of..sorry cant find a 6Aug 05, 2011 9:52 pm If the roof is iron, you can easy lift the sheets and pump or insert insulation. The roof is the most important are of a house to insulate. Depends how cold it gets where you are, but the norm now is for somewhere around R3.5 for roofs. The walls are the second important area, and usually around R2.5 Timber clad and gyprock internals ? Can be done but this is a bit harder. Possibly remove the gyprock (expensive and messy), possibly pump in through holes ? Not sure here as I have never had to deal with it personally. I would contact a professional insulation company for advice (One where Peter Garrett does not work at ) Re: near flat roofs.........insulation of..sorry cant find a 7Aug 11, 2011 9:19 pm thank you so much everyone. i didnt get back to this thread after i didnt see a reply for a bit . the house has a iron roof. gyprock for ceilings....not cathedral retro fit is seemingly the answer then....somehow. my own house offer fell tho so my offer on this or any other house is now in limbo . this house is still in the running tho ....if i get a sale. now i know it is possible to do... i will get someone to quote me if it goes ahead. the house will be both cold and hot.....raised wooden floors, which i would keep, are great for summer.... but not so much for winter .......unless they also are insulated. which makes the house uneconomic to do that. i thank you all heaps for your thoughts and ideas. they are appreciated Re: near flat roofs.........insulation of..sorry cant find a 8Aug 13, 2011 9:29 am Bradford also have a high performance batt that is 90ml thick, and will give an R2.7. This can sit on the ceiling with no air gap below (needs the batten air gap above. They also have a 70ml thick one that gives an R2 rating. You wouldn't need to re=roof to put it in. We were going to use foilboard, however, dust sitting on the shiny surface reduces the effectiveness of the insulation, and we are in a very dusty area, so we are going for the high performance bulk insulation. Added bonus is it is made in Australia, whereas foilboard is imported. Support the home grown product Sorry! I'm new to this forum and have made a mistake in my posting!
