Overview

Concept of Radiant Barrier

"COMFORTABILITY" is the most important element for mankind. The major contributor to the comfort is temperature.

Heat is the source of temperature changes, which can be transfered in three ways; Conduction, Convection and Radiation. The transfer of heat occurs from a warmer to a colder region. Conduction and Convection can only be transferred through a medium or physical contact, whereas Radiation can be transfered across a perfect vacuum as the radiant energy travels in straight line through space.

The roof is the surface of a building that is most exposed to solar radiation and the solar gain absorbed by the roof is directly transmitted down to the attic space. When a radiant barrier is placed underneath the roof covering, leaving an air space, almost all radiant heat will be eliminated. In cold climate regions, the radiant barrier holds the heat inside the building closed environment

Installing a Radient Barrier is the best solution to save energy, either in a hot or cold climate region. The Radient Barrier performs at its best with other roofing solutions that provide a batten cavity space and ventilation.
