![]() You can easily integrate radiant barriers into a newly constructed home, but they can also be installed in an existing house, mainly if the attic is open. If you decide to do the radiant barrier insulation installation independently, thoroughly examine the manufacturer's instructions, take all necessary safety measures, and verify your area's building and fire regulations. How to install reflective insulation in the attic? Working with a certified attic specialist is advisable because a radiant barrier's efficiency depends on being installed correctly. Meanwhile, manufacturers design fiber-reinforced radiant barriers to be more durable and easier to handle. Manufacturers create different types of radiant barriers with either aluminum foil or another highly reflective material that they usually place on one or both sides of various substrates, such as kraft paper, plastic films, cardboard, oriented strand board, or an air infiltration barrier material. Using a smaller air conditioning system may be possible because of the lower heat gain. Radiant barriers can lower cooling bills by 5% to 10% when utilized in a hot, sunny region like Dallas. Installing radiant barriers in the attic space of a house is a common way to reduce heat gain during the summer and see reduced cooling costs. ![]() Radiant barriers work harder when there are considerable temperature differences between the two sides of the attic radiant barrier. What is the R-value of a radiant barrier? A radiant barrier doesn't have an R-value because it doesn't resist heat flow like insulation, but it blocks an impressive 97% of radiant heat from the sun instead of soaking it in.Ī radiant barrier is optimal when installed at a straight line at an angle of 90° to the incoming radiant energy. Radiant barrier insulation has a reflective surface that reflects heat away. Attic elements like the air ducts, attic floor, and the rooms below eventually absorb heat from the heated roof.ĭoes reflective insulation work? When installing a radiant barrier and reflective insulation, there is less heat transmission between the roof, attic surfaces, and the living spaces below. This results in radiant heat transfer from the side of the roofing material exposed to the sun to the attic side of your roof. The sun's radiant energy (or simply, the sun's energy) causes a roof to heat up. If you're thinking about installing a radiant barrier, keep reading. They are built to last and won't cause significant issues for decades. How long a radiant barrier lasts is the question most often asked by customers.Īs long as homeowners or certified attic specialists install them appropriately, radiant barriers last anywhere from 80 to 100 years. Radiant barriers block heat from entering and escaping via the attic and help you save money on utility bills. One of the most common forms of insulation for households is radiant barrier insulation. Debating if a radiant barrier is a wise investment? Here is everything you need to know about radiant barriers and how they help protect your home.
