What is a radiant barrier and how does it work?
A radiant barrier is a type of reflective insulation that is designed to reflect radiant heat rather than absorb it. It is typically installed in attics and crawl spaces to help reduce heat gain in the summer and heat loss in the winter. The barrier is usually made of a thin, shiny material such as aluminum foil or plastic film, which is attached to a substrate such as foam board or fiberglass batts.
The radiant barrier works by reflecting radiant heat away from living spaces, rather than allowing it to be absorbed by the insulation and then transferred to the living space. This can help to reduce cooling costs in the summer by keeping the attic space cooler, and can also help to reduce heating costs in the winter by keeping the attic space warmer. By reducing heat gain and heat loss, radiant barriers can help to improve the overall energy efficiency of a building.
