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.

This Ecofoil Radiant Barrier is keeping us alive by keeping out the Heat!

This radiant barrier is strong, thin and light but powerful! We put it on our A-frame ceiling to act as a buffer between the overwhelming heat of the sun, and the inside of our house. (There is no attic on an A-frame).
We used painters tape and staples, where necessary to keep it up.
The change in temperature was immediate. Our ceiling temperature (using an infrared thermometer gun to measure temperature) dropped 15 degrees IMMEDIATELY! The internal temperature of our ceiling used to measure 112 degrees during the peak of the sun, and now, with the radiant barrier on it, measures possibly 87. Life changer. It may not be ideally beautiful, but it's not terrible looking and we can now live somewhat comfortably in our home during the summer. Love this Ecofoil!!!

Best Cooling Foil Ever

This is an excellent radiant barrier foil. My garage has felt 10 degrees cooler since I installed it. The amount of foil I bought, 500 sq ft., was great for my garage and most of my home. Thank you.

Easy to install, seems sturdy enough, and seems like it works

Installing to the rafters on a 1915 home with minimal insulation in poor shape.
It goes up straight and the fibers between the layers keep it from pulling through the staples.
I haven't measured temps in the attic to compare before/after, but it seems cooler and I have not finished installing it.
I would purchase again, but I don't need nearly as much as I thought, so will probably have enough leftover for another house

Versatile installation…

I was able to install this product another way with the same benefits of a garage attic roof installation. This product was easy and most of all durable while installing. I’m excited about the cost effectiveness this product will bring, given the purchase price and the insulation effectiveness it pays back in return.

Installing radiant barrier under joists

Installing EcoFoil Attic Foil Insulation is a Breeze

Attic foil 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. Reflective attic insulation works wonders on its own or when combined with traditional insulation (fiberglass or foam) you may already have in your attic. When installing reflective 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".

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.
