Why use radiant barrier insulation in your attic

Why install reflective insulation in your attic?

In hot climates, attic temperatures can reach as high as 140° F. The radiant heat in the attic tries to force its way into your living space, making your air conditioner work harder, which in turn, increases utility expenses. In colder climates, 50-75% of heat can escape into your attic, making your heater work overtime to keep your living area warm and comfortable. EcoFoil’s reflective attic insulation combats these inefficiencies by reflecting 96% of radiant heat, either away from your home, or back into your home, depending on the source of the heat.

See how it works

Radiant Barrier improves performance of existing attic insulation

Traditional insulation works to absorb heat and cold air from passing through. This only goes so far. Unwanted air still passes through eventually, even when high R-values are used. Installing a reflective barrier in your attic creates a true radiant heat barrier. When radiant barrier attic insulation is combined with traditional insulation, you get the benefits of both. These benefits combine for an effective one-two punch that keeps your living space warmer in the winter and cooler in the summer, saving you money on energy bills year round.

Attic Foil Insulation

Ensuring that your attic is properly insulated is an important step in increasing the efficiency of your HVAC system, and keeping your home comfortable in both hot and cold climates. EcoFoil Perforated Radiant Barrier does just that, while also preventing moisture build-up that could cause mold, mildew, and rotting.

In hot climates, attic temperatures can reach as high as 140° F. The radiant heat in the attic tries to force its way into your living space, making your air conditioner work harder, which in turn, increases utility expenses. Conversely, in cold climates, 50-75% of heat can be lost through the attic space, making your heater work overtime to keep your living area warm. EcoFoil’s reflective attic insulation combats these inefficiencies by reflecting 96% of radiant heat, either away from your home, or back into your home, depending on the source of the heat. For more in-depth information, check out our “How Does a Radiant Barrier Work” page.

EcoFoil Perforated Radiant Barrier is the most appropriate product for attic reflective barrier applications, and is suitable for any climate. This reflective attic foil prevents excess heat gain in the warm summer months, and prevents heat loss in the cooler, winter months. The perforations in the reflective attic insulation prevent condensation build-up, while still delivering 96% reflectivity of radiant heat.

Excellent Vapor Barrier for Sauna use

I work in Sauna Construction and we've used this product as a vapor barrier in the saunas we construct. It's easy to work with and does a great job keeping the vapor where it belongs and helping our saunas work as intended.

Ecofoil is great product

Lightweight, effective in reflecting heat and acting as a radiant heat barrier, this stuff works and is worth the cost. The savings in a/c costs is worth the expense and trouble to install in the attic.
