R+HEATSHIELD is Innovative Energy's line of radiant barrier insulation products made from a woven polyethylene material covered by a foil film. This metalized film provides a reflective surface that blocks 95 percent of radiant heat, so it helps keep spaces cooler in summer and warmer in winter. R+HEATSHIELD can dramatically improve thermal performance and energy efficiency, keeping energy costs lower and interior spaces more comfortable.
The main difference between a radiant heat barrier and a reflective insulation product relates to the way in which it is installed. Reflective insulations are typically installed within cavities that incorporate air spaces between the foil insulation and the cavity materials, as in a wall. Radiant barrier insulation is typically installed with one reflective surface facing a large open air space, which makes it ideal for insulating an attic.
