Is low-E insulation good?

It greatly reduces attic heat gain making this space more usable and the rest of the house cooler. LOW-E Reflective Insulation resists all three types of heat transfer: convection, conduction, and radiation. This space age product also provides a full vapor barrier with sound deadening properties.

What is Low-e roof?

In much the same way, Low-E ThermaSheet® Insulated Roofing Underlayment provides a thermal break between the blazing heat of the sun and your cool air conditioned house. Low-E ThermaSheet® reduces the temperature below your roof deck which means your house uses less energy and your pockets lose less money!

What is the R value of low-E insulation?

When evaluated behind hollow backed vinyl siding, Low-E™ HouseWrap has an R-value of 4.

What is Low-E Therma sheet?

Low-E Therma-Sheet insulation has 99% pure polished aluminum facings. The facings are heat laminated to a closed cell polyethylene foam core. It is installed over top of traditional felt paper or other underlayments.

What does Low-E glass do?

Low-E coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. When heat or light energy is absorbed by glass, it is either shifted away by moving air or re-radiated by the glass surface.

What is Low-E window film?

LOW-E FILM CONTROLS LIGHT AND THERMAL TRANSMISSION With its low-emittance surface facing the room, low-e film also helps lower solar heat gain during the cooling season, as a greater fraction of the energy absorbed by the window is prevented from entering the building.

Can I put radiant barrier under insulation?

If installed on top of attic floor insulation, the foil will be susceptible to dust accumulation and may trap moisture in fiber insulation, so it is strongly recommended that you NOT apply radiant barriers directly on top of the attic floor insulation.

Does foil insulation really work?

Foil is used in space-faring craft because of these great properties preventing radiant heat loss. Because space is a vacuum, there is very little heat lost by conduction, so foil is absolutely perfect.

What is the R value of reflective foil insulation?

Reflective insulation can have an R value anywhere from R-3 all the way up to R-17.

Can I install radiant barrier under shingles?

You can install the radiant barrier foil below the raised shingles either on top or below the battens. The easiest and best way is to run the foil out over the roofing felt, tack it down and then install the battens followed by shingles or metal roofing.

How long do low-e windows last?
