utilityshield
The Utility Shield™ is a 5-layer, perforated, reflective energy-shield. It’s two outer layers of 99.9% aluminum foil reflect 97% of radiant heat. It is marketed by Utility Management Association.
Each layer of foil is bonded to a tough layer of Mylar and has an interwoven nylon scrim for extra added strength. It's so strong it's virtually impossible to tear! It also has a Class 1, Class A fire rating!
The Utility Shield™ reflects the sun's infrared rays in the hot summer months, which allow your home to be more comfortable. In the winter months, it reflects escaping heat back into your home, once again adding comfort.
You’ll find that hot and cold spots in your home are eliminated summer and winter. You’ll find yourself enjoying greater comfort in your home. And, since it doesn’t use energy to increase your level of comfort, you’ll have your utility bills.
Radiant heat -- the major source of heat flow that enters our homes in the summer and escapes our homes in the winter -- is energy in the form of infrared waves. It travels at the speed of light, even through a vacuum, and is either transmitted through, absorbed into, or reflected by any material it contacts. Air, water and glass, for example, transmit visible light in varying degrees. A white surface, such as snow, reflects it; and the black surface absorbs it. The Utility Shield™ reflects up to 97% of radiant energy striking its surface.
