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:if I compress roof insulation does it still work?
Yes, but not as well. the air trapped inside it works as an insulator as much as the fill itself. The weight of insulation on top of it will take away some insulating properties, but it's replaced by the insulating properties of the new insulation, so it's a net gain.
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:what would be average hourly wage for roof insulation installer on the gold coast?
Depends on whether you are employed or working contract. Currently it could be 18-25 per hr for employee or upto 40 per hr for contract depending on allowances and if you are providing your own vehicle or company vehicle. Then are you doing bats or anticon, it is usually charged on a sqm rate. Call some roofing companies or insulation companies and ask them what their rates are.
Q:do i leave air gap in attic roof for insulation?
The best way to set up an attic is to put a vapor barrier under the rafters (before nailing on the gyproc), then put the insulation (fibreglas batts) between the rafters to full depth (10 or 12 inches). Soffit vents are installed under the eaves at the sides of the roof, and gable vents are placed near the peak of the roof at the ends. This allows for airflow resulting from convection, particularly important in the summer months to remove heat buildup in the attic. If the insulation is adequate, it will not only isolate this heat buildup from the inside of the house in summer, but will prevent heat loss to the attic in winter. (The airflow in winter will be minimal, but will remove any moisture/condensation that might collect otherwise.)
Q:We are putting a tin roof cap. Do we put some sort of insulation/stripping under the tin roof cap?
Those foam strips they sell you to go under the ridge caps will eventually dry out, blow out, and be hanging all over the place. Caulking won't fill a 5/8's gap to keep the wind/rain out, and tar has no place whatsoever on a metal roof, you'll get it all over everything, and either one will look like ****. The best ridge cap has to be custom made and cut to fit. I use a 12" wide X 10' strip, bent in half to pitch, and then turn down 90 degrees on the edges, whatever the rib height is, usually 5/8". Hold the ridge cap in place on the ridge and mark where the ribs are, then notch out for the ribs so that the cap sits flush over the ribs and down on the flats, punch holes and screw down thru the tops of the ribs. It's a little time consuming but it makes for a good looking finished product that won't wear out.
Q:Is it a practice in the US to use board insulation as a retrofit under pitched roofing material?
The sip panels are vented depending on what thickness over all that you want. The last ones I used had 4 inches of rigid foam board then on top of that had 3" strips every 16" an inch thick which created an airspace. On top was 5/8 Osb. To create an affective air flow the fascia cannot plane through with the plywood at the bottom but fall just short of the 1" space. To cap it a oversized vented drip edge is used. You must also have a ridge vent for proper flow. These panels can near 100$. You can do it your own way like I do when building log cabins by laying 2" foam down first then lay 2x4 16 on center on top then finally your plywood. If you use CDX instead of Osb it will outlast it by 100%. Rigid foam insulation is not like batt-faced. Rfboard ins. Is used in boat hulls and even after being submerged for long periods of time will return to its original density and r-value. For obvious reasons batt ins. Will not. You won't have a moisture problem as long as you don't have a venting problem. If you are using high hat lighting don't let the cans touch your rigid ins. Tuck batt in softly around them TAKE THE PAPER OFF! By code if you have an interior wall 10or more ft. It must have a fireblock, simply a 2x4 turned flat between the studs. On your roof the ceiling you see inside, (most likely 7/8 tongue and groove boards) passes as the same. Good luck!
Q:How to make a building roof insulated against solar heat?
If you're redoing the roof, a radiant barrier under the sheathing helps. So does insulation. And also, if there is an attic space there, consider putting in a fan to blow the hot air out.
Q:where a cwsc is located in the roof space of a dwelling and the space beneath it contains thermal insulation?
struggling to understand your question! are you talking about a storage tank? what is the problem with the insulation? if it is in the way move it but insulation under a tank is not a problem the tank will need to be insulated any way!
Q:Metal roof condensation issue low budget? Spray-on insulation?
hope this helps. With more air movement there will not be so much condensation. it is a matter of having an inlet for air or a fan and then an outlet for air. There are small extractor fans i have one for my bathroom, but unsure of the cost.
Q:Does a layer of snow on my roof provide insulation?
I mostly shows that your home is well insulated and not loosing heat through the ceiling to melt it. Think of an Igloo made of packed snow. It can be kept at a temperature just below freezing so that it will not melt and still keep those inside from the 30-60 below outside.
