Product Description:

building heat insulation material  is an environment friendly product which has good sound absorption and insulation properties. The outer layer of PET provides excellent abrading and tears resistance. The middle layer of bubble shows strong ability in barrier of moisture and oxygen, reduction and insulation of sound. The middle layer also has the advantages like reflecting light and heat and stopping the penetration of ultraviolet radiation.

Q:Best roofing insulation against radiant heat (sun)...pls help.?
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:Does a layer of snow on my roof provide insulation?
Yes, it does. It also shows that you are not losing heat and that you are well insulated.
Q:I want to install a new roof, what are the best insulation options?
The new metal roofs offer both the durability and the insulation. Metal roofs come in many shades and are made to reflect the heat away from the house. The insulation in these roofs are often the highest R factor.
Q:once we have insulated our attic roof,is it ok to use plastic cladding over the top of the insulation,?
i think it might be able to pass code if you ever sell the house.i myself would use sheets of white wainscoting.also make sure the insulation if it has a paper backing ,paper faces the room.
Q:Best insulation for Pex tubing 3/4 pipe in the roof? HELP!!!?
Check into heat tape tied to pipe, with insulation wrapped around that. turns on when freezing temperatures. insulation by itself, will not stop it from freezing if left for long periods without water moving through it. .
Q:My upstairs ceilings are not insulated and on the other side of the 2x6 rafters is the roof.?
Suggestion: install the insulation with the foam channels but leave the center section (roof ridge area) open from end to end. At each end you can install a static vent or an active one. Depending on the amount of space you have you may be able to install a power vent.If you can send me a diagram with measurements I can give you a more definitive answer.
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:Why would a 1960's homebuilder use insulation on the roof rafters?
No building codes back then, and maybe he was thinking about putting an extra room up there then you would have to insulate the rafters also
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?
I think you'll get more bang for you buck just going with the radiant barrier and having a continuous ridge vent.
