Q: No insulation was installed under roof of my 2 story home. Im not rich but looking for info on installing about 450 ft. up there.: Based on the geography you are put up insulation rates would differ, I would suggest initially you just call Insulation contractors who offer free home energy audits and ask them to give their estimate , based on the rates you choose one which suits your budget. Usually type of insulation you choose determines your rate, so do a little homework on it

Q: I do not have extra space on the roof. Roof also tapers to drains at one end of building.: the R values, i am not sure. that white stuff is NOT Styrofoam. it is a cheap imitation. Real Styrofoam is made by DuPont, is usually a light blue, with a plastic seal coat on both sides. that thin plastic seal coat doubles the R value. what really does the insulation, is trapped air. air is actually a poor conductor of heat. the foam is actually little bubbles of air. dead air that is, air that cannot circulate and move. it works similarly to the way a down vest or coat works, it fluffs up and holds the air pockets out within a confining structure, thus retaining heat. the rigid stuff will last much longer, i can tell you that much. the white foam stuff deteriorates quickly. buy cheap, get cheap, is the general rule. you may wind up only having to do it again in a few years.

Q: In a house, it looks like an addition, that now is the kitchen , it feels HOT, it doesn't seem to have a very good insulation on the roof at all, the ceiling is already low, so, what can be done on the outside to give it more insulation?, i don't care what it is i just want to give it a GOOD insulation, the roof is flat and to shingles. Any IDEAS? , thanks!: So there is no access above the ceiling, like a crawl space? If you cannot get above the ceiling to look then it will be difficult to determine, what you have or don't have up there. You may want to consult an insulation company for help. They may have ideas to blow in additional insulation. The spray foam that is on the link left by the other person is a foam sprayed on the roof decking and rafters when you have complete access to them. The person below me brings up another point, can you add any soffet vents to help with air flow?

Q: roof was replaced eight years ago soon after there were leaks in the roof caused insulation toget wet then dry now the insulation is packed hard and has started to turn into power who would be responsible to replace the insulation.: House Owner, Land Lord. If you are the house owner, contact the people who did the work on your roof, find out what your warranty is.

Q: What is the aim of insulation in walls and in roofs?: Insulation can reduce your heating cost. Insulating your solid walls could cut your heating costs considerably, because solid walls let through twice as much heat as cavity walls do.

Q: I have read in some articles about roofing that it is recommended to use attic roof insulation in ones roofing. Is this true?: here in the uk not only is it necessary ..its the law ..under building control up to 250mm 10" of fibreglass is needed ...it keeps house warm in winter and cool in summer

Q: we have liq. ammonia storage tank (capacity 40000 ton)having double wall & suspended deck.liq. NH3 stored at temp -33 degree cent. insulation (form ) being provided to annular space (wall ) but not on top roof . can you explain for exact reason.with regardsanvar shaikh: Insulation is less necessary on the roof. The ammonia is mostly a liquid, and a liquid would absorb heat rapidly from tank walls. Above the liquid is vapor, and vapor absorb heat much less rapidly than liquid does, so insulation is less important there.

Q: i have about 200 sq ft of odd shaped polystyrene foam (rigid) insulation between 3&quot; and 5&quot; thick. it's leftover from installing a flat roof on a commercial building. creative ideas anyone? grind it and use it as attic insulation in a home?thanks.: I'm a bit confused here Andy. If the flat roof needs replacing, when it is removed what is revealed is going to be exactly what you would see if you removed the ceilings. So why consider removing the ceilings if they are ok? When the flat roof is replaced put the insulation in then. Whilst rockwool would have been the material to use there is now roofing insulation board that is much more efficient, 50mm board gives equivalent insulation of something like 150mm rockwool. If the flatroof isn't fitted with suitable vents to keep it ventilated fit them when the roof is done too. The only reason I can see for replacing the ceiling plasterboard is if it hasn't got a vapor barrier ie foil backed board.

Q: What can i do to add more insulation in a addition in my house?The Roof is flat on this addition (no attic room for insulation there).Looks like it's only 4 or 5 inches thick, starts from the inside with 1/2 inch drywall and the rest is plywood, and then that black sheeting on the outside.IS THERE ANYTHING MORE THAT CAN BE DONE TO ADD MORE INSULATION ON THE OUTSIDE?, (i can't do anything on the inside since the ceiling is already low) SINCE IN THIS ROOM IS VERY HOT, even touching the celing feels warm, PLEASE HELP!: You could have foam roofing installed over the existing roof covering. Look up "foam roofing" on the Internet.

Q: I would like to know which direction the one side with foil faces. The roof or the interior of the room?This is an attic room. Roof being &quot;raw&quot; i mean that it looks like cedar tongue in groove boards...then shingles on top of them. Which way do i face the foil side of the sheet..?thanx: The foil side should go to the outside. I believe it's a moisture barrier.
