Q:Have a patio with metal roof, gets very hot during summer. Will Great Stuff insulate and stick to hot roof during summer? Thanks

I don't think Great Stuff foam insulation is meant to be applied in the manner in which you need. It is used to fill gaps and cracks, not be sprayed out in thin coats. whenever I've used it in the past, I found out it did not like to be spread out, or "worked".

Q:The attic was converted into two rooms and I want to add insulation but the space between the ceiling of the rooms and the roof is about 5 inches? How should I do this?

there is not any way no how ever that a roofing nail is going to show 4 to 5 inches after dealing with shingles and plywood. that should recommend a 5 a million/2" to 6 a million/2" nail. and there is only the slightest quantity of buckle and/or carry earlier the summer time solar flattens it completely. you should call in an self sufficient roof repairer and have him recommend you. until eventually you're seeing issues very incorrect, this is an entire screw-up. If it fairly is actual, then the extra important question is .....in the event that they could do some thing this nuts, what else have they botched? If self sufficient roof repairer supplies you undesirable information, do no longer seek advice from contractor until eventually you have first talked to an attorney.

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 build a pitched roof on top of the flat roof.

Q:My boyfriend has just moved into a flat in a newly converted house. He's up in the loft, and has just discovered that the roof isn't insulated.Does the landlord have a legal obligation to insulate the roof?

To comply with UK building regulations all lofts must be insulated... Q22. How much loft insulation do I need? A22. To meet current Building Regulations you need 270mm of mineral wool insulation. 100mm between the ceiling joists and 170mm laid over the joists.

Q:I'm thinking of converting my brick walled corrugated iron shed into a changing room for winter hot tub use. I was advised by a friend that the first thing i should do is insulate the roof using glass fibre insulation (the yellow fluffy stuff in the loft) and a simple Plywood ceiling but im not sure how i would stick it to the existing roof (dimensions 170cm x 147cm). So..... how should i insulate the roof of my future changing room????

If the roof has joists, which I imagine it would, you would put the bats of insulation into those spaces... these can then be stapled into place or if that isn't possible, you can run a wire between the joists to hold the bats in place. If using faced insulation be sure to put the paper side towards the warm area (inside) to prevent condensation.

Q:We have plenty down at the center, so many, you can carpet a garden. So, since I'll have to tear down the roof and improve the insulation in a few months, I was thinking of adding one extra layer... of emergency blankets. Since they can reflect the sun's heat up, and the heat under it down, will they do that for a whole house? Will the plastic film cause water condensation? If you wouldn't recommend it, then what would you recommend?

They may help, but as thin as they are, installing them would be about as easy as putting socks on a rooster!

Q:i live in a tropical country and i need to insulate my roof to block off the heat from the sun...which insulation would best help me? aluminum foil with foam, real foil with foam or PE with foam? pls help...thank u so much!

Expanded polystyrene (EPS) comes in sheets and is very long lasting and safe to use - no fibers, no itchy skin, no breathing issues....this is also used to keep cold out as well as heat and is durable.

Q: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.

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:do i have to have insulation in my roof?

I think about 80% of heat loss during cold weather is through the ceiling and into the attic in an uninsulated home. So if you mean should your attic be insulated...yes. It will pay for itself in fuel savings and make your home more comfortable.

Q:Hi, I have got a physics question and was just wondering about it.. Can someone pls tell me how does roof insulation work? how is it effective? How does the insulation changes the heat circulation and transfer inside a house?I know that the insulation prevents radiation from the sun and overheating.. but any more details about radiation, convection and conduction of heat pls?

Well insulation makes a dead air space (air is stagnant). Since the air is not moving the transfer of hot and cold is slowed down considerably. But since you have to create cross ventilation to reduce rotting in wood and the build up of explosive gasses. Its a crap shoot that it even does any good. Radiation is heat so that's covered by the dead air space. Convection is usually not an issue with the cross venting. Also for conduction the insulation should slow it down considerably.
