More Facts About RetroFoam

Increases your comfort in all weather
RetroFoam’s R-value (R-value measures insulation effectiveness) reaches a remarkable R-4.6 per inch in winter and R-4.1 per inch in summer. This is the highest annual R-value of any re-insulation option on the market today.

RetroFoam™ provides homes with 2×4 studs R-values of R-16.0 and R-14.9 for winter and summer, respectively. R-values for homes with 2×6 studs reach R-23.7.

RetroFoam™ also eliminates drafts by sealing plugs, switches, cracks, and anywhere else air can enter or leave your home.

Continues to save money over time.
Unlike blown-in cellulose or fiberglass, RetroFoam™ will not settle over time, change shape, or breakdown. Your RetroFoam™ insulation stays in place, particularly at the top of walls where it is most needed. And RetroFoam™ is not affected by moisture. If the foam gets damp, it always dries and remains 100% effective.

Therefore, the high R-values and insulation effectiveness achieved by RetroFoam™ continue over time.

Resists pests
RetroFoam™ is also an effective pest barrier. Because it seals cracks and crevices in walls and cement blocks, it helps keep critters outside.

Does not disrupt your life when installed
RetroFoam™ installation is an easy process in most types of buildings, typically completed in less than a day. Our installers inject RetroFoam™ into the wall cavity, so there’s no need to tear out walls. Since RetroFoam™ is installed from the outside in most cases, you do not need to move furniture or clean up the inside of your home.

Decreases noise: a sound solution
Although RetroFoam™ is used primarily to save energy, our customers often comment about how quiet their homes become once RetroFoam™ is installed. RetroFoam™ reduces noise levels by 75%, a 45-50 db reduction on average. Apartment and condominium residents find RetroFoam™ a great solution for noisy walls.

Reduces taxes
RetroFoam™ is an Energy Star approved product. Therefore, when you install RetroFoam™, you may be eligible for federal tax credits to offset the installation costs! Ask a dealer for details.

Slows the spread of fire
RetroFoam™ is a nonflammable product. RetroFoam™ adds safety and value to your home because fires burn more slowly through RetroFoam™-filled walls.

Never hurts the environment
Non-toxic and completely safe, RetroFoam™ produces no fumes, gases or emissions. It’s also hypoallergenic. RetroFoam™ is safe for the environment and your family.
