Radiant barrier sprays are not true radiant barriers because they only block 75% to 85% of radiant heat. Reflective barrier sprays are ceramic paint solutions with metallic additives, typically sprayed on the underside of the roof deck. Additional DIY supplies cost $200 to $950. Radiant barrier spray costs $250 to $400 per 5-gallon bucket, which covers 500 to 2,000 square feet, depending on the brand. Cost savings also depend on the home's thermal insulation levels and orientation to the sun. Installing a radiant barrier can save $45 to $90 per year on cooling costs in hot climates or $12 to $24 per year in cooler regions. Radiant barriers and reflective insulation both require air space to be effective. Use reflective insulation when an additional R-value is needed to satisfy building codes or regulations. Use a radiant barrier to block radiant heat. The terms "radiant barrier" and "reflective insulation" are often used interchangeably, but they are different materials. Two-sided radiant barrier foil is up to 50% more effective than single-sided foil when installed with air space on both sides. Radiant barrier foil insulation prices are $0.10 to $1.10 per square foot for the material alone, depending on the type. The radiant barrier is often installed as part of the roof deck, requiring no additional labor. existing home – Adding a radiant barrier during new home construction is typically cheaper. A radiant barrier may cause damage if the attic is not adequately ventilated. A radiant barrier combined with thermal attic insulation combats all heat transfer types – radiation, conduction, and convection.Īttic fan installation costs $300 to $900. A radiant barrier is typically a one-time purchase as its effectiveness does not degrade.Īttic insulation costs $1 to $4 per square foot installed. Quality – Higher quality materials cost more but are more durable. Still, most spray-on barrier coatings are not as effective and are not considered true radiant barriers.

The following factors affect the cost to install a radiant barrier:Īttic size – Larger attics require more material and labor.īarrier type – Reflective, low-emittance paint may cost less than radiant barrier foil. Radiant barrier can work in tandem with other insulating materials and increase their effectiveness.Contractor installing radiant barrier in attic This rating system is exclusive to materials that slow conductive heat - like bat and roll or blown-in insulation. Radiant barrier has no R-value on its own. A local mold remediation specialist can help fix any issues if mold has already formed.
#ATTIC RADIANT BARRIER INSULATION PRO#
A pro will be able to prevent this problem with proper installation. Radiant barrier insulation can cause mold if it is not installed correctly. In fact, this often improves its efficiency. Yes, you can install radiant barrier over new or existing insulation. Can you put radiant barrier over insulation? Although it usually works best when coupled with normal insulation. Radiant barriers can keep your home cool more effectively than insulation in some cases. Is radiant barrier better than insulation?
#ATTIC RADIANT BARRIER INSULATION UPGRADE#
Radiant barriers are an energy efficient upgrade that can save you as much as 10 percent on their heating bills. Installers can staple radiant barriers up on their own or lay the material over existing insulation. However, it is possible to DIY install this insulation with care. Department of Energy recommends homeowners hire a radiant barrier installer to make sure the job gets done right. Radiant barrier won’t work at peak capacity if it’s incorrectly installed. If homeowners upgrade to R19 insulation, they can save from $180 to $300 on heating bills. Cooler climates typically save $15 per year on average with a radiant barrier upgrade.
Homeowners in hot climates can save as much as 10 percent on their heating bills, or about $120 off per year. Return to Top How Much Does Radiant Barrier Save? Radiant barriers do not have insulating material attached, but you can install them over new or existing insulation to maximize the efficiency of both materials. Reflective insulation is insulating material (like batt and roll insulation) that has at least one reflective surface. To maximize cooling efficiency, the system must include an air gap between the reflective surface and the interior of the roof. This is most effective when coupled with reflective insulation. To create a radiant barrier, pros install metal foil over the rafters in an attic and reflect the sun’s heat away from the home. Department of Energy, residential radiant barriers help homeowners lower air conditioning costs and lessen the impact of summer heat.
