• Keep radiant heat out of your attic

    Prevent excess heat gain in the warm summer months by blocking unwanted radiant heat under your attic's rafters.

  • Prevent heat from escaping

    In colder months, keep your furnace running efficiently by reflecting heat back into your living space—saving on energy costs.

  • Promote air flow in your attic

    Tiny perforations promote air flow, preventing buildup of condensation which can lead to mold and mildew.

Why install Radiant Barrier 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. When Perforated Radiant Barrier is combined with existing 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.

Easy to work with

This product is easy to work with and feels high quality. Cannot judge performance yet and don’t have another product to compare it to but I’m confident that the radiant barrier will pay for itself relatively quickly in terms of energy bills.

Installed on the rafters, can already tell a difference.

Product is very easy to work with and install. Effectiveness of product will be determined in the upcoming warm months here in Western NY state.

Installing EcoFoil Attic Insulation is a Breeze

Attic insulation can be installed on your attic rafters or above your ceiling joists, with minimal equipment needed. All you'll need are scissors or a utility knife to cut the product, and a staple gun to fasten it in place. It works wonders on its own or when combined with traditional insulation (fiberglass or foam) you may already have in your attic. When installing radiant barrier on the floor of your attic, simply place a layer on top of your existing fiberglass insulation, making sure to overlap each row by 2-3".
