How Radiant Barrier Works | Smart Foam Insulation marketplace

Ever wonder why your attic gets so hot during the summer? Let's explore how radiant barriers can keep your attic cool and improve your home's energy efficiency. During hot days, your roof absorbs a large amount of solar radiation. This heat penetrates your roofing materials and radiates into your attic, causing temperatures to soar. The primary way heat enters your attic is through radiation. The sun's rays heat the roof, and this heat radiates downward, warming the attic space. This is where radiant barriers come in. A radiant barrier is a reflective material that reduces the transfer of radiant heat. Radiant barriers are typically installed on the underside of the roof or on the attic floor. Their highly reflective surface blocks radiant heat, reflecting it away from the attic. When the sun's heat hits the radiant barrier, it gets reflected back towards the roof instead of being absorbed into the attic space. This significantly reduces the temperature in the attic. With a radiant barrier, the attic stays much cooler. This reduces the heat load on your air conditioning system, leading to lower energy consumption and increased comfort. The science behind radiant barriers lies in their ability to reflect infrared radiation. Most radiant barriers are made of a thin layer of reflective material, often aluminum, which is excellent at reflecting radiant energy. Installing a radiant barrier is a straightforward process that can have a significant impact on your home's thermal performance. By reflecting radiant heat, these barriers keep attics cooler and reduce the overall cooling demand. Radiant barriers are an effective way to enhance your home's energy efficiency. They work well in both hot and cold climates, helping to keep homes cooler in summer and warmer in winter by reducing heat transfer. In summary, radiant barriers reflect radiant heat away from your attic, maintaining a cooler space and reducing energy costs.
