Radiant Barrier by PowerSave

Minimize Heating & Cooling Costs Radiant Barrier insulation reduces both summer heat gain and winter heat loss. Radiant barrier consists of a highly reflective, aluminum-clad material that reflects (or more specifically, re-emits) radiant heat rather than absorbing it. Radiant barrier insulation is a reflective insulation system that offers a permanent way to reduce energy costs,

Minimize Heating & Cooling Costs

Radiant Barrier insulation reduces both summer heat gain and winter heat loss. Radiant barrier consists of a highly reflective, aluminum-clad material that reflects (or more specifically, re-emits) radiant heat rather than absorbing it. Radiant barrier insulation is a reflective insulation system that offers a permanent way to reduce energy costs, lower attic temperature, and promote greater comforter in your home.

How it Works

During the summer, radiant heat from the sun is absorbed by your roof and is transferred to underlying roofing materials. On a typical summer day, when the outdoor temperature is 90º, the temperature in your attic can rise to an astounding 140º F! When radiant heat permeates your attic, the confined space in your attic acts like an oven, super-heating the air. This unwanted heat transmits directly into your living space below.
