Choosing to install a radiant E Barrier System is entirely up to the home owner but remember each and every day you do not have a properly functioning energy efficient attic is a day wasted paying more for your utilities. Your home will be more comfortable and energy efficient once a Radiant E Barrier has been installed.

What is Spray - on Radiant Barrier?

Spray-on Radiant Barrier is essentially a “liquid foil” coating. We all know that foil is a heat barrier. There are many out on the market but our firm recommends Sherwin Williams E-Barrier reflective paint.

Here are the reasons why

• Lower utility cost and increased thermal comfort – A home owner will see and feel the rewards of their investment.
• Durability – E-Barrier is durable and last a long time with little or no maintenance.
• Ease of Clean up – Since it is water based it is easy to clean up and emits no long term odors as does some two part component e barriers.
• Breathability – Damaging moisture vapors won’t be trapped in the wood substrates.

E-Barrier installations can reduce your heating and cooling bills by as much as 15% as certified by an independent testing laboratory.*

* Energy savings will vary depending on building materials, home location and conditions.

What is Radiant Energy?

Radiant energy comes from the sun in waves. When those waves strike the roof of a home or building, the roof absorbs that heat, creating increased temperatures in the attic, which is eventually transferred throughout the building. On warm days, this radiant heat results in increased air conditioning costs. On cool days, this radiant heat comes from and inside source such as the heater, and escapes through the attic. Heat and energy costs are literally going out the roof.

This transfer of heat is called emissivity. The lower the emissivity or e-rating, the better the product is the better it is at preventing radiant heat energy from entering or leaving the building. Sherwin Williams E – Barrier has a low emissivity rating. E-Barrier has been tested by studies with utility companies. Engineers have verified that the product E – Barrier made by Sherwin Williams has a low emissivity of .32. This means that if installed properly up to 68% of the radiant energy is reflected back*.

E-Barrier is a single component, latex based coating. It does not require any mixing. It goes on just like paint with and airless sprayer. It goes on fast and dries fast and is a low odor product unlike some two part epoxy based systems.

How is it Applied?

Radiant barrier spray paints are sprayed directly on the underside of the roof deck.

Return on Investment.

A radiant barrier, depending on the type of barrier, can usually pay for itself in between 2-5 years. Other factors such as utility rates going up can reduce that time frame *.
