Reduce Cooling Costs By 10% With NASA-Developed Radiant Barrier Technology

Originally developed by NASA to protect astronauts from space radiation, radiant barrier insulation can help keep your home cooler in the summer too! It looks like something straight out of science fiction because, in a way, it is!

Supplement Your Insulation with A Radiant Barrier to Save More in the Summer

Radiant barrier installation reduces your summer cooling bills by reflecting radiant heat from the underside of the roof up and away from your home. By preventing this radiant energy from being absorbed by your existing insulation, your home stays cooler, even under the harsh sun of summer.

The Benefits of Radiant Barrier Insulation

Cooler Attic & Increased Energy Efficiency

Radiant barriers lower your attic temperature, helping your air conditioning units experience less stress, allowing them to last longer and saving you more money over time. When used in conjunction with traditional fiberglass insulation, homeowners can expect to see their energy bills fall by 5% during warm spring and summer months.

More Comfortable Living Spaces

By reducing the amount of radiant energy pouring through your ceiling, top floor and south facing rooms will be more comfortable even in the dog days of summer. It is important to pair a radiant barrier with traditional insulation as reflective insulation only prevents radiant heat transfer and does not help with heat transfer via convection or conduction.

Easy Attic Storage

Adding insulation to your attic can result in reduced attic floor space – and for some folks this means losing out on valuable real estate for storing holiday decorations! Radiant barriers provide efficiency improvements without reducing your attic space.

Radiant Barrier FAQs

Do radiant barriers increase the R-Value of my insulation?

No, radiant barriers actually prevent a different sort of heat transfer. R-Value is a number used to describe a material’s resistance to the flow of heat, and this flow takes place via conduction. Conduction describes the type of heat transfer through objects that are touching one another, while radiant barriers reduce radiant transmission.

Do radiant barriers help in hot climates?

Yes, attic radiant barriers yield the greatest energy savings in hot climates where homes have HVAC ductwork in the attic. Many homes are built in exactly this way and are great candidates for a radiant barrier.

How do radiant barriers work?

Radiant barriers work by layering reflective materials, such as aluminum foil, atop a substrate like plywood or flexible plastic sheeting. These barriers reduce heat gain in your attic by reflecting infrared light (heat) away from your home.

Can I use radiant barrier insulation instead of traditional attic insulation?

Generally, it is not recommended to only use radiant barrier insulation. Instead, radiant barriers are best used as a supplement to other insulation materials, like blown fiberglass insulation.

How long does radiant barrier insulation last?

Foil insulation lasts an incredibly long time, easily providing benefits for decades. Dust build-up can reduce their efficacy, however when installed correctly this effect will be negligible.
