Radiant Barrier Sheathing

TechShield Radiant Barrier Sheathing represents the best in energy-efficient building technology. With TechShield on the roof deck, attics stay cooler, cooling loads are reduced, and energy consumption goes down.

When radiant energy from the sun strikes a surface, it is converted to heat energy. A radiant barrier reflects radiant heat and does not emit it to the cooler surfaces around it. The effectiveness of a radiant barrier is determined by how much radiant heat it reflects and how little heat energy it transmits - a property called emissivity. Measured on a scale of zero to one, the lower the emissivity, the more effective the radiant barrier.

The California Energy Commission recently enacted revisions to Title 24 Energy Efficiency Standards that mandate the use of radiant barriers on all new residential housing (when using the prescriptive method of compliance) in specified "hot" zones.
