FAQ

Would it be worth forwarding the offer to the client? Is the difference that substantial?

You don't want that. If he offers 3.5 instead of the required 3, that is a different story. Otherwise he should give you more material thickness to provide an equivalent R of 3. Yes, the difference can be substantial and I wouldn't forward it to the client. The smaller the R value of the entire roof sandwich the larger the difference it makes. Like the change from 5 mpg to 4 mpg is a 25% worsening in fuel economy, but a change from 100 mpg to 99 mpg is 1%. It will mess up the heating/cooling of the building and the mechanical systems might be inadequate. They could save money on the roof and complain how the building is too hot/too cold or the mechanical systems never shut off and their energy bills are too high.

i mean, what do you use to make it stay put? glue? nails?

Steel spreaders may be cheapest (as described in other answer) but many roofs have shingle nails sticking out,a couple dabs of caulking,glue,you're done! Be sure anything you use is compatible with your foam,some will just MELT it. Good Luck! DrJ

I am thinking about getting cavity wall and roof insulation at the moment.But since summer is approaching, I fear that getting the insulation will mean that the house will be very hot at night. (During day time the house will accumulate heat from the sun, and the heat cannot escape).I also fear that the ventilation will be bad and the air in the house will not be as fresh.Any advice please?

please stop worrying.your house will be warmer,but not hot.it is also a good idea to open your windows for at least 20 mins a day to allow claen/fresh air to circulate.you are correct in doing the job now though.

House is a bi-level. Recently added storm windows to deck off dining room. Having a new rubber roof installed would like to know if we can insulate ceiling to make the room warmer. What product do you suggest we use. we are getting conflicting answers, some say you can insulate others say the ceiling needs to breath having a rubber roof install. Please advise.

Your other answerer is correct. The little plastic pieces that he speaks of are sometimes called baffles. They look like they are corregated or wavy like the inside of cardboard. These are essential to letting air flow in the attic space. Another item that you must have are vents on the soffits or overhangs on either side of the roof. Air has to get in there somehow. There are alot of homes that are not ventilated properly and the roof decking or plywood gets discolored and rots from the inside out. Sometimes this can happen in as little as 5 years, depending on your geographical location. Rubber roofing is usually put on a flat roof system. If you do not have access to inside the framing, you cannot insulate or it will be very difficult to get insulation in there properly. There are so many variables with different houses and locations. You may want to ask an insulation expert from the phone book or even a home inspector. Good luck.

The distance between knee wall and attic ceiling is about 6 foot. Could I push a perforated pipe between the rafters?

That is an option. And there aren't many options.Not much is going to slide easily behind the insulation. I'm thinking --------------------. You are undoubtedly going to snag on roof nails coming through the decking. I don't know if they would hold up but the cardboard tubes wrapping paper comes on might work if you tape 2 together. and flatten and tape the end you will be pushing in first. cut slots with utility knife. I think your idea would work if you can afford the pipe. That's a tough one. When we convert attics we line those cavities with a styrofoam insulation chute end to end until we reach open ventilation-you probably know that by now. Give it a try.

i have about 200 sq ft of odd shaped polystyrene foam (rigid) insulation between 3" and 5" 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.

Without loft insulation ,the roof space is full of air.Why does this not keep the heat in?

Because air can circulate, (it's called convection) and transfer a lot of heat. In other words, air alone is a very poor insulator. .

i like to put a layer of sand in roofing instead of insulation. it's fireproof and insulates better. plus it's free. how much weight can ceiling board handle? I find about 15 inches poured into the roof works fine so far. Saves me about $1600 each house built

first sand is very heavy and will probably exceed the loading on the roof and walls the extra reinforcing you would need to make the house SAFE would far outway any savings
