AcryShield A502 Roof Coating...Often Imitated, Never Duplicated

Posted by Nicole Gale on Thu, Jun 12, 2014 @ 11:00 AM

roof coatingAcryShield A502 was introduced by National Coatings Corporation in 2006 after three years of intensive research, including both laboratory and actual in-service field testing.  The coating was designed to provide a primer/base coat to be applied to thermoplastic and thermoset single ply membranes, such as PVC, PIB, CPE, TPO and EPDM.  Previously, the only primers used for coating these membranes were solvent borne, which required warning labels, had very high VOC (volatile organic content) and required extreme care when applying to prevent fumes from entering the building.  The only other option for coating EPDM was a "prewash" or "rinseable primer" that had a very high, corrosive  pH, so high that it would react with human skin oils, causing chemical burns. 

AcryShield A502 has three inherent advantages over the previously used primers:

  • It is water borne, so there is no concern about flammable solvents or fumes entering buildings.
  • It replaces both specialty primers for the thermoplastic membranes and the corrosive rinseable primer for EPDM.  Thus there is no need for separate primer/basecoats for different types of roofing membranes.

The next time a project calls for coating single-ply roofing membranes, the roofing contractor, consultant or specifier should demand National Coatings Corporation AcryShield A502

Reflective Roof Coatings Save on Energy Cost

Posted by Nicole Gale on Tue, Jun 03, 2014 @ 11:00 AM

Reflective Roof CoatingsNational Coatings' reflective roof coatings can reflect up to 92% of the sun's heat/harmful UV rays. This drastically reduces energy consumption and use of HVAC systems to lower the temperatures inside the building. Reflective roof coatings are excellent at reducing roof temperatures and prohibiting a majority of heat absorption into the building. They work by reflecting the sun’s heat back into the atmosphere, preventing the roof and building from absorbing the heat, resulting in greater energy efficiency, cooler interior building temperatures, less temperature fluctuations throughout the day, greater cost savings on energy utility bills and increase comfort for your tenants and customers occupying the building.

The reflective roof coatings work similarly to wearing a black shirt versus a white shirt on a hot day. The white shirt keeps you cooler, more comfortable and the black shirt attracts the heat and in turns makes you hotter. A cool roof using reflective roof coatings is a monolithic, watertight, spray applied system that is installed directly on top of your existing roof membrane (asphalt, single-ply, SPF, concrete, or metal) to protect and extend your original roofs’ lifespan. Reflective roof coatings are excellent for reducing energy consumption by keeping the building cool, but they also provide durable protection from the harmful UV rays. The sun’s UV rays are the leading cause of roof failure as they dry out and cause your roof to crack, become brittle, tear and eventually leak. Reflective roof coatings do not absorb the majority of the UV rays; therefore, protecting your roof membrane by prohibiting premature roof failure and damage to be done to your roof.

According to ENERGY STAR®, “Americans spend about $40 billion annually to air condition buildings – sixth[sic] of all electricity generated in this country.” Installing a Cool Roof with reflective roof coatings can drastically reduce this amount of energy consumption cost.  National Coatings cool roof coatings significantly lowers roof surface temperatures, extending roof life, directly impacting the temperature of the interior building, allowing it to remain cooler - reducing the use of HVAC equipment to cool your building.

What is "Critical Peak Pricing?" How does it Relate to Roofing?

Posted by Nicole Gale on Thu, May 08, 2014 @ 11:00 AM
More specifically: How can electrical utility initiatives help me save money when I coat my roof white?

Critical Peak Pricing (CPP) is a pricing model used by electrical utilities where the cost per kilowatt-hour varies, depending on time of day.  Electricity peak demand times, usually in the afternoon in the summer, will be charged at a premium or higher rate than other times during a 24 hour period.  The term "net metering" is sometimes used to determine and record peak demand.   Electrical utility companies have begun installing "net meters" that calculate kilowatt usage during "peak demand" and "normal or low demand" periods.  This information is used to determine costs based on this two-tier pricing model. 

"So how does this relate to roofing?" If the user can reduce electrical usage, they will save money.  This can easily be accomplished by reducing air conditioning electricity usage.  A very easy and cost-efficient way to achieve this is to coat the building's roof with a white reflective roof coating

The roof life extension benefits of white reflective roof coatings have been well documented.  Now, the initiative described above offers even more of an incentive to coat your roofs white with National Coatings AcryShield roof coatings. Download our Roof Coating Systems brochure to find out more.
