New Study Shows Reflectivity’s Effect on Energy Usage – Numbers Help Confirm Impact of Gulf Coast Supply’s Roofing Products

Share Article

Gulf Coast Supply & Manufacturing, LLC, (http://www.GulfCoastSupply.com) has for years touted how the reflectivity of its metal roofs combined with reflective foil insulation can have a substantial effect on energy consumption. Now a new study that included NASA scientists, released just this month, helps confirm that approach by showing variations of up 42 degrees, based on roof reflectivity.

A study that included scientists from the National Aeronautics and Space Administration (NASA) helps put into perspective how big an impact the reflectivity of a roof can have. The numbers reinforce what Gulf Coast Supply & Manufacturing, LLC, (http://www.GulfCoastSupply.com) has stipulated for years: Reflectivity can dramatically affect energy costs.

Here’s what NASA published at http://www.nasa.gov/topics/earth/features/ny-roofs.html:

“On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its ‘urban heat island’ effect.”

The results of the roof study were published March 7 in Environmental Research Letters, a peer-reviewed scientific journal covering research in all aspects of environmental science. The lead author was Stuart Gaffin, a scientist at Columbia University, who noted that widespread implementation of such “cool roofs” could help cut down on energy usage and greenhouse gas emissions.

Though the concept of roof reflectivity is not new, and its attributes are generally understood, Gaffin’s data puts it into a much broader perspective when it comes to analysis on a citywide scale, such as in New York.

But individual homeowners don’t have to wait for the collection of additional data to benefit from the energy-savings offered right now by reflectivity.

An example: Reflective foil insulation.

“Reflective foil insulation is an effective solar energy barrier that can greatly reduce the transfer of radiant heat through siding and roofing,” explains Jonathan Sherrill, Gulf Coast Supply vice president. “While most insulating materials rely on retarding the flow of heat through walls and ceiling, reflective foil insulation works by reflecting as much as 97 percent of the radiant energy back away from its surface.”

The GCS executive added that such reflectivity helps dramatically cut energy costs in air-conditioned housing, as well as create an effective “shade” in non-cooled out-buildings, garages, porches and utility buildings.

Sherrill and his crew should know. Gulf Coast Supply has been a leader in manufacturing metal roofing and components, serving architects, contractors and homeowners across the Southeast since 1996, and providing durable, economic and attractive products for the growing demand of metal roofing.

“Our friendly and experienced staff is ready to answer any technical questions customers may have,” Sherrill said. “Our familiarity with current building trends, Florida building codes and our experience in assisting customers with order placement works together to ensure orders are complete and ready when needed.”

In addition to the products available at its headquarters in Horseshoe Beach, Gulf Coast Supply has two new locations that opened last year. They are:

GCS Alachua – The 7,000-square-foot manufacturing facility is at 14480 NW US Highway 441, Alachua, FL, 32615, which is just off Interstate 75, less than 20 miles from the University of Florida in Gainesville. It is well-suited to expedite delivery and service to Central Florida, one of the state’s key population centers.

GCS Stuart – A 7,000-square-foot manufacturing facility at 8701 SW Old Kansas Ave., in Stuart, FL, 34997 (Martin County) is a perfect fit for the Treasure Coast, whose communities stretch from Hobe Sound and Jupiter in the south to Sebastian in the north and include Port St. Lucie, Fort Pierce, and Vero Beach.

Staff at all three locations can answer questions about the energy-efficiency and eco-friendliness of metal roofing, as well as the impact reflectivity can have on energy-savings.

“Everyone in our sales staff is trained and knowledgeable, especially on metal roofing,” Sherrill said.
