What is reflective thermal insulation?
Reflective thermal insulation works on a different physic behavior as compared to conventional thermal insulation. It uses high reflective surface(s) with low emissivity adjacent to airspaces to bar or frustrate the flow of heat into or out of a building.
Does reflective insulation keep heat out?
Unlike mass insulation, reflective insulation is able to keep heat in and reflect heat away. Mass insulation material like fiberglass and foam merely slow down the transfer of heat; they do not reflect heat away, nor do they keep heat in.
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.
Why is reflective insulation good?
Reflective insulation, installed in the attic ceiling, helps reflect sunlight and reduce the radiant heat transfer from the underside of the roof to the other surfaces in the attic. This helps keep your home cooler and more comfortable.
Does reflective insulation keep cold in?
A radiant barrier stops heat from escaping when it’s cold and keeps heat from getting into your home when it’s hot. Making your home cooler in the Summer and warmer in the Winter.

Generally speaking, reflective insulation is good for keeping heat out, and bulk insulation is good for keeping heat in. Bulk insulation is, as the name suggests, the bulky kind.
What is heat reflective insulation?
Wall Installations.
Do attic radiant barriers work?
So if you have cooler attic your A/C system does not have to work as hard to air condition your building. Radiant barriers can reduce attic temperatures 20 degrees to 35 degrees. The radiant barrier creates a cooler attic which helps reduce cooling costs. There are also some comfort improvements.
Does attic radiant barrier work?
In short Yes, Attic Radiant Barrier Does Work!! We only say radiant barrier doesn’t work because we know of a product that works even better and can save you over twice as much as current radiant barrier technology.
