Radiant Barrier and Radiant Barrier Insulation
R+HEATSHIELD HD is Innovative Energy’s line of Radiant Barrier insulation products made from a woven polyethylene material covered by a metalized film. This metalized film provides a reflective surface that blocks 95% of radiant heat, so it helps keep spaces cooler in summer and warmer in winter. R+HEATSHIELD HD can dramatically improve thermal performance and energy efficiency, keeping energy costs lower and interior spaces more comfortable. newsblogs. Radiant Barrier Insulation is reflective material that is used to effectively block the transfer of radiant heat. Radiant barriers typically come in sheets with a highly reflective surface on one or both sides, depending upon the application. A good radiant barrier blocks 95% of radiant heat transfer, making it highly effective at controlling the transfer of heat from one space to another. For example, installed properly in an attic, a radiant barrier will make the attic cooler in the summer, leading to lower cooling costs and a more comfortable home. Radiation is the transfer of heat (infra-red radiant energy) from a hot surface to a cold surface across an air space or vacuum. All surfaces including those of a radiator, stove, a ceiling or roof and insulation radiate to different degrees. The radiant heat is invisible and has no temperature, just energy. When this energy strikes another surface, it is absorbed and increases the temperature of that surface. This concept can be understood with the following example: On a bright sunny day, radiant heat from the sun travels through a carââ¬â¢s window, strikes the steering wheel and is absorbed, causing it to become hot.
