Homes in the Austin area need a radiant barrier in the attic to help reduce heat gain during the sweltering Texas heat and to help decrease exorbitant home cooling costs. Radiant barriers are made of a highly reflective material that reflects heat instead of absorbing it. In order to keep your home cool, a radiant barrier in your attic needs to be combined with adequate insulation and air sealing.

A Radiant Barrier for Your Attic

Since heat travels through the air from warm areas to cool areas through convection, conduction and radiation, radiant barriers work best in conjunction with insulation. Insulation slows conduction, and to a lesser extent, convection. An effective radiant barrier in the attic reduces heat transfer from the outdoors via radiation.

As the Texas sun shines on your roof, it’s generally the sun’s radiant energy that heats the roof. A large amount of heat then travels down through your home via conduction. As the first line of defense, a radiant barrier prevents your home from getting too hot and exerting additional energy on cooling. Various studies have shown that a home’s radiant barrier can reduce cooling costs by about 5% to 10% when used in a climate similar to that of Texas.

Professional Radiant Barrier Installation

Only a radiant barrier that is installed properly will be effective. The expert team at Hill County Insulation can help retrofit your home with a radiant barrier. We will staple the reflective material to the bottom of the rafters, ensure appropriate airflow and take measures to minimize dust build up.
