Attic access is one of the largest gaps in your efforts to effectively insulate your home. Seal your attic door access from heat loss and cold drafts with the easy-to-install REACHBARRIER Attic Door Radiant Barrier Kit!
To understand why radiant barrier is such an effective attic door insulator, it helps to understand the two modes of heat transfer and how they work.
Heat travels by a mixture of conduction, convection, and radiation. Fiberglass, cellulose and foam are all designed to stop the flow of convective and conductive heat.
Although each of these insulation types is effective, they are not designed to stop the flow of radiant heat.
Reflective foil insulation and radiant barrier technology block up to 95% of radiant heat.
