Buying Guide for the Best Attic Radiant Barrier
Choosing an attic radiant barrier can help improve your home's energy efficiency by reflecting radiant heat, keeping your home cooler in the summer and warmer in the winter. To select the best fit, you should consider the unique conditions of your attic, such as size, ventilation, climate, and how accessible the space is for installation. A good approach is to match the product’s properties with your needs and house characteristics for optimal results.ReflectivityReflectivity is a measure of how much radiant heat a barrier can reflect away from your attic space. This is important because higher reflectivity means better performance in cutting heat transfer. Reflectivity typically ranges from around 85% to 97%, with the higher percentages indicating stronger performance. If you live in a hotter climate or want maximum energy savings, look for products with higher reflectivity. In milder climates, lower values can still provide benefits without being overkill.
EmissivityEmissivity tells you how much heat the material will emit versus absorb, and lower numbers are better because they show less heat is passed on. Values usually fall between 0.03 to 0.10. An attic barrier with very low emissivity will minimize the amount of heat that enters your home, so if your main goal is to reduce cooling costs, focus on products with the lowest emissivity you can find.
Material TypeAttic radiant barriers are made from different materials, most commonly from aluminum foil (single or double-sided), sometimes with reinforcement like a plastic mesh. The type of material influences durability and installation method. Aluminum foil is lightweight and highly reflective, while reinforced barriers add strength for easier handling and better tear resistance. If your attic is used for storage or you expect a lot of foot traffic, a stronger, reinforced type is generally better.
Perforation and BreathabilityBreathability determines if the barrier allows moisture or air to pass through. Non-perforated barriers block moisture, which can sometimes lead to condensation issues if your attic isn't well ventilated. Perforated barriers allow water vapor to escape, which can help reduce moisture problems. If you have a humid climate or suspect your attic isn’t perfectly dry, a perforated option can be safer.
Installation MethodRadiant barriers can be stapled to rafters, laid on attic floors, or integrated during roof replacement. The method you choose depends on attic accessibility, existing insulation, and whether you're installing it yourself or hiring help. Stapling to rafters is common and keeps the barrier out of the way, but requires some maneuvering. Laying on the attic floor is simplest but can be less effective and may get covered by dust over time. Think about how often you use your attic and your comfort with DIY work when deciding.
DurabilityDurability refers to how well the barrier holds up over time against tearing, dust, pests, or moisture. Longer-lasting barriers are usually reinforced in some way and offer resistance to damage, which is important if your attic is a high-traffic area or if you’ll be moving items around. If you rarely enter the attic, a standard, less expensive barrier will often suffice.
Fire ResistanceSome radiant barriers are treated to be fire-resistant, which can add a layer of safety in case of attic fires. This is particularly important in areas prone to wildfires or for peace of mind in safeguarding your home. If fire safety is a top concern for you, check for certifications or ratings showing the barrier has been tested for fire resistance.
