Attic radiant barrier insulation12/6/2023 For additional information please contact Tom Porter, (210) 848-5658 or visit CPS Energy Rebate Program website. The recommended level for most attics is to insulate to R-38 or about 13 to 14 inches.ĬPS Energy presently offers a rebate program to help offset the cost of adding insulation to your attic floor or foam insulation on the attic roof decking. The higher the R-Value, the better the thermal performance of the insulation. Insulation levels are specified by R-Value, which is a measure of the insulation’s ability to resist heat flow. ![]() It is important that the insulation be evenly distributed because sometimes there is enough insulation in the middle of the attic but very little along the eaves. Radiant barriers are designed to reflect heat away from the attic to help keep the temperature of the attic and the house below cooler. If your insulation level is below your floor joists and less than 14 inches deep you should add more loose fill fiberglass insulation. By reflecting much of the suns radiant heat away from your roof, a radiant barrier applied to the underside of your roof decking in the attic works with. No matter what kind of insulation you currently have in your attic, you can quickly determine if you need more by looking across the span of your attic. Properly insulating your home or building helps to maintain comfortable temperatures year-round. Dear Don: A radiant barrier reflects radiant heat and can be used to keep heat in a home during the winter and to keep heat out in the summer. Fi-Foil offers both single-layer Radiant Shield™ and multilayer Silver Shield™.Reasons to call Geo-Insulation as your home insulation contractor And, radiant barrier installation can be done in conjunction with other forms of insulation. Although it is possible to calculate an R-value for a specific radiant barrier or reflective insulation installation. Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits a radiant barrier. A radiant barrier works best when it is perpendicular to the radiant energy striking it. A multilayer attic radiant barrier can also improve HVAC duct and system performance by up to 50% which can afford builders an opportunity to use a smaller load system for their projects.Īn attic radiant heat barrier can also be perforated, allowing controlled water vapor transmission. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. For example, installing a radiant barrier in an attic that already has high levels of insulation (R-30 or above) would result in much lower energy savings than in an attic insulated at a low level (R-11 or less). Call us at 40 for a Radiant Barrier quote today. ![]() Your house will be the coolest in Central Florida. Hopefully, we’ve made the case for installing and using a radiant barrier. That means lower energy bills and faster cooling. Also, your AC unit won’t need to work nearly as hard to cool it down. If the insulation in your attic stays cooler, your living space stays cooler. A multilayer attic radiant barrier installation can reflect 97% of radiant heat at the roof to reduce attic temperatures by up to 30 degrees in the summer and keep homes warmer and more comfortable in the winter. The amount of thermal insulation affects the potential radiant barrier energy savings. If you think your house is cool now, just wait until our insulation team goes to work. Second, insulation is made better by a radiant barrier. Low-emittance (Low-e) radiant barrier foil is one of the best ways to insulate buildings from heat gain or loss in extreme seasonal temperatures. Radiant barriers are particularly effective in hot climates, especially when air ducts are located in the attic.īecause attic radiant barriers effectively reduce radiant heat transfer, they are often used in conjunction with other thermal insulation such as fiberglass, spray foam and other building materials to provide a Systems Engineering approach to improve building performance and lower Home Energy Rating Scores (HERS). Most heat enters and leaves the home through the attic and roof, so installing a radiant barrier in the attic can dramatically impact your homes heating and. ![]() Radiant barriers are available in several forms. Radiant Barrier RadiantGUARD Xtreme Heavy Duty Reinforced Attic Foil Insulation 1000 sq ft 48-inch by 250-feet Perforated Breathable Radiant Barrier. Attic Radiant Barriers - Silver Shield™ Attic Radiant BarrierĪn Attic Radiant Barrier system is commonly used to reduce summer heat gain and winter heat loss in new building construction or retrofit in order to improve comfort, lower conditioning and heating costs and prolong the life of HVAC systems.Īttic radiant heat barriers work by blocking or reflecting UV heat that would otherwise cause temperatures to rise in the bounded open-air space(s) in the attic. Unlike foam or cellulose, however, radiant heat barriers reflect heat back to its source.
