A radiant barrier is a little-known and commonly overlooked feature of roofing in Dallas and Fort Worth, but one you should be acquainted with. These fixtures are installed mainly in attics for the purpose of reducing summer heat and minimizing cooling costs. Unlike thermal insulation materials, they don’t reduce heat conduction, but they do reflect radiant heat instead of absorbing it.
At Hometown Roofing, we can install a radiant barrier in your residential home or commercial business. We service the Dallas and Fort Worth areas, which can benefit from this type of roofing service. Contact us today for more information.
To better understand what radiant barriers do, it’s important to know how heat travels. Conduction, convection and radiation are the methods by which heat travels from a warm location to a cooler one.
- Conduction works by transferring heat from a hotter location through a material into a cooler location, similar to the way heat travels from a hot pot of soup through a metal spoon and into your hand.
- Convection occurs when a liquid or gas heats up, loses density, and rises, later falling as it cools.
- Radiant heat will warm anything solid that can absorb its energy.
Most insulation materials reduce only conductive and convective heat flow, but not radiant. Since the sun’s rays are primarily responsible for heating up your roof, a radiant barrier helps cool it down by reducing the radiant heat transfer from the roof to the inside of your attic. Radiant barriers are generally most effective in hotter climates, and particularly in attics containing cooling air ducts. According to some studies, a radiant barrier can help to reduce cooling costs by 5 to 10 percent in a hot climate common in Dallas and Fort Worth.
