Radient Barrier, Foil Heat Reflective Roofing Insulation

Sold by Roof - It

Description

Radiant barrier insulation is a reflective insulation system that offers a permanent way to reduce heat. Radiant barrier insulation reflects radiant heat energy instead of trying to absorb it. It consists of a pure aluminized film which is unaffected by humidity and will continue to perform at a consistent level no matter how humid it may be. This is not kitchen foil (kitchen foil is only about 20% aluminum; this is 99.5% pure aluminum).

Most people are familiar with traditional insulating materials such as fibreglass, Styrofoam and rock wool. These products use their ability to absorb or resist (slow down) convective and conducive heat transfer to insulate (R-value). A third seldom discussed but dominant form of heat transfer that exists is: RADIANT HEAT TRANSFER.

A radiant barrier insulation reflects radiant heat energy instead of trying to absorb it. There are two properties on which radiant barrier works: Reflectivity and Emissivity. First, the aluminum is reflective on the hot side, reflecting most of the heat from where it came. Second and most important, aluminum has a low emissivity of between 0.03 and 0.05. This means that only 2% of the heat is emitted to the inside of the building.
