Q:Can you put fiberglass insulation on the under side of roof tiles in the loft in the house?
You should not be able to see your roof tiles from inside your house. So no, it can not be done. You can attach insulation to the rafters if that is what you meant.
Q:I want to install a new roof, what are the best insulation options?
No matter what material you use for the actual roofing, make sure you have a Radiant Barrier installed at the same time. There are several different ways this can be achieved, your roofing contractor can (and should) advise you on the best method for your home.
Q:Do loft flats have to have roof insulation installed?
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:do we need insulation if we have a roof tile?
. Insulation does a bunch of things; it hinders heat transfer and also Noise transfer. If the pitter-patter of rain doesn't bother you, you're ok. This tile is popular in California where the temperature is often mild. Of course people living in the Sierra Nevada Mts. wouldn't agree, but installation might NOT be necessary for you. Stick a 'remote thermometer' up there to monitor the temp. See the comfortHouse link below >>> .
Q:Are flat roofs the best roof structure for insulation?
Hm. Tough one. Could be. I would think because there is less surface area.
Q:Best roofing insulation to keep warm in the winter?
You mean the insulation that you put in your attic or crawlspace? That fiberglass stuff works pretty good- just roll it on out- the thicker it is the higher the R factor. Just remember to not reduce the air circulation especially around eaves, or you'll get condensation.
Q:do I have to blow insulation in the roof of my mobile home if I install foam insulation under a meatle roof?
I don't think you can blow insulation in that area. It is to small of an area to get insulation into.
Q:Good uses for leftover foam roof insulation from a flat roof?
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:Is it good to get cavity wall / roof insulation in the summer?
Insulation works to keep a home cooler in summer as well as warmer in winter. And the warm months generally mean better conditions for the installation because of less potential moisture, which sometimes forms in uninsulated homes in the freezing cold, being trapped in ceiling and wall cavities. To have your ceiling insulation function properly, attic ventilation is required. This is approx. 1 sq. ft./ clear ventilation to 300 sq. ft. of attic space. More is better than less. You will find your home cooler. Insulation on its own does not change ventilation. This is an air/vapor barrier situation which also should be considered when insulating.
Q:what effect does changing the pitch of a roof have on the insulation properties and durability of a roof?
Increasing the pitch will of course result in a larger dead air space therefore more insulation. The greater pitch is also less likely to leak but of course more costly to construct as more material is needed. Install vents at the peaks for more efficiency. Shingles will be less likely to be lifted by high winds with the steeper roof also.
