Radiant Barrier Simulated Attic Heat Test – EnerflexFoil.com
www.EnerflexFoil.com What is radiant heat and how does Enerflex radiant barrier foil reflect it? An simple way to comprehend the concept of radiant heat is to stand in front of your grill throughout a cookout. The heat you feel standing next to the grill is deemed radiant heat. A radiant barrier will reflect that heat. Heat that is radiated does not necessarily have to come from the sun. Enerflex radiant foil barrier is installed inside your attic, beneath the roof sheathing, so how is it expected to reflect the sun’s rays? The answer is it doesn’t have to reflect the sun’s rays to operate, but it does reflect the radiant heat generated from those rays. On a hot day, heat from the sun is absorbed by the roof and warms up the sheathing beneath, which radiates heat towards the attic floor and standard insulation. All materials emit radiant heat to varying degrees based on their surface temperature. However, installing a radiant foil barrier like Enerflex will reflect up to 96% of this radiant energy back toward the roof. The result The top surface of the insulation is up to 30° cooler than it would have been which reduces the amount of heat that moves through the insulation to the living areas below.
