Product Description:

aluminum foil building 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: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:What are the roof insulation materials?
Polystyrene foam is divided into expansive EPS and continuous extrusion type XPS two: polystyrene board full name polystyrene foam board, also known as foam board or EPS board
Q:Is mineral wool any good for under roof insulation?
Yes, be sure to leave an air space between the top of the insulation and the roof deck to allow for ventilation, and use a vapor barrier on the interior side of the insulation.
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:How best to insulate interior of attic roof?
You can avoid the condensation problem by simply leaving a minimum 2'' gap between the roof and the insulation. You need to fix battens on to the rafters ( at least 2'' from the tiles ) and then fix blanket or rigid insulation tight between them. The battens will maintain the air space. You then need to fix a vapour barrier over the whole thing and finish with plasterboard. No small job to do it properly ! ps you need to check the condition of the roof before you start and fix any loose tiles etc Alternatively, turn the heating up and wear a thicker sweater.
Q:Whats a good way to insulate water pipes on our roof?
Contact a local remodeling contractor and install the new piping system properly. Even a system under a foundation can be repaired, but it is not cheap to do it.
Q:If a roofing contractor offers an insulation material with an R value of 2.5 instead of 3?
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.
Q:What is the difference between roof and loft insulations?
Potentially that the roof itself is insulated on the underside. A loft insulation could be that the base or floor of the loft/ attic is insulated. Otherwise, I'm not sure.
Q:What's better- to lay out roof insulation in an old house or to get it blown in?
anybody can do either.nothing to it.i prefer blown, because it isnt near as itchy.you can rent the blower from home stores, but it takes 2 people to run.
Q:My roof is a spray on white foam/insulation. What is the correct name for this type of roof?
redneck style roofing
