Attic Radiant Barrier
How the Artic Radiant Barrier Works. The heat energy of the sun is reflected by the Barrier but does not disturb the moving of heat through the scientific concepts of convection and conduction. Heat is reduced by lower the temperature in the interior spaces. Other materials use conduction to slow he process of heat transfer. Cellulose, foam and fiberglass are conduction materials. A radiant barrier however, reflects radiant energy. In cold weather, radiant barriers connected to foam installation. Most homes do not come with pre-installed Radiant Barriers, but it can improve your costs by 17% and up to 20% in warmer climates. (Barrier Options)
The design of radiant barriers are for saving energy in all types of buildings. For this reason they designed with different choices for you to save energy, they do have certain perks and limitations.
Foil Faced Plastic– Foil faced plastic consist of a very thin membrane that acts as a barrier. It is most efficient when it is stapled to the rafters at the bottom edges.
Foil-Faced Foam insulation– these are uncompromising types of foam insulation that offer top performance by limiting energy loss through conduction.
Radiant Barrier Paint– This type of paint is normally applied in spray form. It does not perform as well as the other Radiant Barriers.
