As we know all too well, summers in North Carolina are hot and long. And even though the outside temperatures can get blistering, there is a place in your home that gets much hotter. That place is your attic. On warm sunny days, heat from the sun radiates down and is absorbed into the dark colored shingles on your roof. This radiant heat causes the roof temperatures to soar to as much as 150 degrees. This heat radiates into the attic area and causes the temperatures to climb.
The problem with a hot attic is it makes for high energy bills and a hot house. The warmer your attic is the more energy it will take to keep your home cool in the summer. Radiant barrier is a fantastic product that can be used to combat these high temperatures. In the mid 1950’s, radiant barrier was used by Clark E. Beck to solve the problem of extreme temperatures faced by astronauts when in outer space. Radiant barrier allowed him to develop space suits for NASA that effectively reflected 95% of radiant heat and did the job that would have taken seven feet of standard insulation.
This same technology can help your attic stay much cooler. By installing radiant barrier on the bottom side of the roof rafters, it reflects the radiant heat coming off the roof deck. It works effectively with passive ventilation to allow that heat to escape from the attic. By blocking 97% of radiant heat waves, it will lower your attic temperatures 30 degrees in the peak of the summer. Radiant barrier is one of the products that we get the quickest response from customers about the impact it makes. Often, homes that struggle to keep the upstairs comfortable will see a 3-5 degree drop in temperature in just the first few days.
The big benefits of this product are that it significantly lowers cooling cost, makes your home more comfortable, and makes your attic cooler which extends the life of your AC system. Customers across the Raleigh Durham Triangle have been using this technology to combat the summer time heat.
