Fact: There are over 70 million single family homes in the United States today.
Fact: Many of these homes could improve their energy efficiency by adding a radiant energy barrier.
Problem: Until now, painting contractors have had no method or product to address this problem.
Solution: E-Barrier® Reflective Coating from Sherwin-Williams and application by West Side Painters.
E-Barrier is an aluminum coating for residential attics and commercial metal decking. It reflects radiant energy to help control interior temperatures and cut extra energy costs. Its microscopic metal particles reflect heat, so buildings stay cooler in summer and warmer in winter.
Years in development, this new coating offers painting contractors an excellent opportunity to build their business. E-Barrier is a natural value-added service for residential repaint contractors, and it can also be useful in commercial and new residential projects. Why? Simply put, with today’s rising fuel costs, interest in saving energy has never been higher. At the same time, everyone wants to be more comfortable. That means cooler in summer, warmer in winter. Cooling a home with air conditioning is typically the single largest energy drain for a homeowner – even in most northern climates, where there are three months or more when air-conditioning is in use..
How it works
Radiant energy is energy that comes in waves from the sun. When those waves strike the roof of a home or a building, the roof absorbs that heat. Through absorption, the radiant waves increase temperatures in the attic. Subsequently, the increased temperatures in the attic are eventually transferred throughout the building.
On warm days, this radiant heat results in increased air conditioning costs.
On cool days, radiant energy coming from an inside source, such as a furnace, can escape through the attic.
Either way,what it means to the home or building owner is that heat and energy costs are literally going out the roof. When E-Barrier is applied to the bare underside of an attic roof or commercial metal decking, it creates a barrier that reflects radiant energy, helping to prevent it from entering or leaving the building.
The science behind it
The transfer of energy between a building and the elements is measured as emissivity. Emissivity is rated on a scale between 0 and 1. The lower the number, the better the product is at preventing radiant heat energy from entering the building.
E-Barrier was tested by a certified solar energy center, where laboratory test data and computer simulations were used in conjunction with empirical results from a utility pilot project that involved installation in nine homes. The results from those tests show that E-Barrier has a low emissivity of .32. This means that 68 percent of the radiant heat energy is reflected back. E-Barrier reduces heating and cooling costs by as much as 15% as certified by an independent testing laboratory. This energy savings varies depending on building materials, home location and conditions.
E-Barrier is a single component, latex-based coating. It does not require any mixing. It’s formulated to minimize overspray, a key benefit for painting contractors, especially when working in tight attic spaces. Field tests show that E-Barrier can be applied at the rate of about 1,000 square feet per hour.
E-Barrier goes on just like paint and is easy to apply with an airless sprayer. It covers in one thin coat without dripping or running. Its quick-dry formula makes the job go even faster, while its low odor minimizes disruption to the occupants. In those hard-to-coat areas, E-Barrier can be brushed or rolled.
The Fast Facts On E-Barrier
- An energy saving coating
- A radiant barrier
- A radiant control coating (RCC)
- A radiant barrier system (RBS)
- A reflective coating containing microscopic metal particles that reflect radiant heat
E-Barrier can be applied to:
- Underside of attic roof decking in existing or new homes
- Previously coated metal decking in commercial structures
E-Barrier works by:
- Reflecting away sunlight to keep the building cooler in the summer
- Reducing 68% of the radiant solar heat that enters through the roof - this means there is less heat available to transfer through to the rooms below
- Reflecting interior radiant heat back into the structure keeping it warmer in the winter
- Increased comfort
- Reduced energy costs because less energy is required to keep the structure cooler or warmer
A Glossary of Energy Saving terms
Emissivity: The ability of a surface to radiate or emit energy in the form of infrared radiation. Emissivity is represented by an e-value of zero to one. The lower the number, the more effective the blockage of radiant heat transfer.
Reflective: The percentage of light that is reflected away from a surface.
R-value: A measure of resistance to heat flow through a solid material. The higher the R- value, the higher the insulating quality. An R-value cannot be assigned to a coating. It is only applicable to bulk insulation because it takes into account material thickness and density. A coating is not thick enough to warrant an R-value.
