What is the intended function of radiant barriers?

The intended function of radiant barriers is to reduce summer heat gain and winter heat loss. Radiant barriers are reflective materials installed in attics to minimize the amount of heat that enters a home during the summer and to keep heat from escaping during the winter. They work on the principle of reflecting radiant heat away from the living spaces below, effectively keeping the attic cooler in hot months and warmer in cold months.

These barriers are particularly beneficial in warm climates, where they can significantly lower energy costs by reducing the need for air conditioning in the summer. By reflecting heat, they also help improve the overall comfort of a home throughout the year, contributing to more efficient energy usage and maintaining a stable indoor temperature.
