How Radiant Barriers Contribute To Home Comfort And Energy Savings

July 26, 2012 | Blog

Texas’ Coastal Bend is gearing up for a hot, humid summer, and your air condition will play a crucial role in keeping you comfortable. Give your A/C a hand this season by installing radiant barriers, a reflective material that can help reduce your home’s heat gain and lower the cost to keep you cool.  

Radiant Heat

There are three types of heat: convection, conduction and radiant. Radiant heat is unique because it travels in a straight line. When this type of heat comes from the sun, it travels to a warm, solid surface that absorbs it. When the radiant heat hits your roof, the heat seeks the cool surfaces in your home’s ducts and attic. By installing a radiant barrier in the attic, you’ll help your home reduce the amount of heat that transfers between your roof and the attic.

Radiant Barrier Performance 

A radiant barrier relies on three factors to perform well: emissivity, reflectivity and the angle of installation. Emissivity is the ratio of heat that the surface of a radiant barrier produces and transfers to a comparably sized area. The best radiant barriers have lower levels of emissivity. The reflectivity of a radiant barrier describes the amount of heat the barrier re-emits. The higher the reflectivity the better the barrier works. When installing radiant barriers, the best angle for the sun’s rays to hit them is at a right angle.

Radiant Barrier Types

You can find radiant barriers in the form of shingles, foil and chips, but one of the most popular barriers comes in the form of reflective aluminum roof sheathing or foam board that you install in the attic. Also available is a convenient spray-on barrier that is popular among homeowners who seek a quick solution. A radiant barrier is not a substitute for insulation in your roof or attic; it’s a good addition that will help you stay cool and save on your power bill.

Great Company

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
