Q:can you insulate ceiling if rubber roof installed?
Yes, you can. There is a little plastic piece that you will want to tack to the underside of the roof though before you install your insulation. It is a plastic air vent that keeps about an inch or so of space between the roof and the insulation so that air can move through. You need to do that so the roof can breathe as they say. If you don't allow it to breathe, the difference in temperature from outside to inside will cause the roof to sweat and will make your roof go bad a lot quicker.
Q:How does insulation work to prevent heat transfer in the walls and roof of a house?
All versions of insulation are largely air that is kept from moving - air is a good insulator if convection - movement of heated or cooled air due to changes of density - is prevented. This assumes that a vapor barrier and caulking prevent actual air movement through the wall when a wind is blowing. Some insulators are also poor conductors of heat so the connection between inside and outside that might occur is broken. As it happens, glass used in fiberglass and minerals used in rock wool are actually pretty good conductors of heat in solid form but as fine particles and flakes they don't conduct well from one strand/piece to the next.
Q:where can i find and compare prices on roofing and insulation materials?
It's in euro's but you can convert or get the idea. Also, you have to click on the graphs to get a more clearer image.
Q:should thermal insulation ever be applied directly to the underside of a roof top?
Should it be done, No. Thermal Insulation is put direftly above the ceiling. Not on the actually roof top. The reason being, that even though both methods will trap in heat, With the insulation on the arches of the roof, it still allowing heat into the Attic, Or roof space. This means that the top of the roof will infact be the warmest part of the house, and lot of heat will be lost. from the main rooms of the house.
Q:if I compress roof insulation does it still work?
Yes. But, remember this; it is the trapped air that causes the insulation to work properly. If you squeeze the air out of it, it is less effecient- will not conserve energy as well. I would not compress it at all.
Q:We are putting a tin roof cap. Do we put some sort of insulation/stripping under the tin roof cap?
I'm assuming your talking about a ridge cap normally you would seal it in with tar or polyurethane caulk and put your shingles over it
Q:Is it necessary to have attic roof insulation?
If it's an unfinished attic space, you'll want insulation on top of the ceiling, but not in the rafters which would prevent airflow from your soffit to the ridge vent or gable vent if you have that. You need it on top of your ceiling to stay cool in the summer and warm in the winter.
Q:Can I add reflective attic insulation to the inside of my roof, between the rafters?
yes okorder.com
Q:I need to know if I insulate the roof of my attached garage or just the ceiling?
Insulate the ceiling, not the roof. Place the vapor barrier (foil or heavy paper) facing the garage. For Alberta you want at least R-30, or 9" of fiberglass insulation. The garage should already have eave vents, hold the insulation away about a foot from them so the insulation does not block the air flow from them.
Q:How good is polyurthane spray foam for roof insulation?
we live in the desert, and got our roof coated, and instantly noticed the difference, it is much more insulated, and provides protection against leak (which was the main reason we had it done)
