When it comes to standards, the UL (Underwriters Laboratories Inc.) symbol has got to be as recognizable and respected as it gets. When you see a product or technology that has earned the UL symbol you know it has undergone rigorous review and testing for safety and is appropriate for use as designed. And when Underwriter Laboratories creates a totally new category to accommodate your technology, you know you are entering mainstream acceptance. So welcome Aeroseal into the big time!
A new UL certification category, UL 1381 was recently added by Underwriters Laboratories. The category, “Aerosol Duct Sealants,” was specifically created to address Aeroseal technology and ensure its inclusion as a UL certified duct sealing solution along with traditional manual sealing methods covered by UL181A and B.
“Having the UL symbol is an important criteria for lots of building contractors and others involved in choosing and approving duct sealing methodologies,” said Aeroseal’s president, Amit Gupta, “so acquiring the UL certification is a significant milestone for the company. Having a totally new category created to accommodate this new approach to duct sealing really highlights the innovative nature of the technology and underscores the rapid adoption of its use.”
While the standard is written for all aerosol duct sealants, at this point, there is only one game in town that meets the certification criteria– Aeroseal. The certification includes the sealant’s use with air ducts that are fabricated and installed in accordance with ANSI/SMACNA HVAC duct construction standards for metal and flexible ducts. According to documents from Underwriter Laboratories the aeroseal technology was tested for all various characteristics including surface burning, mold growth and humidity, erosion, interior duct burning, leakage reduction and durability.
“The list of standards bodies that have tested and approved aeroseal technology continues to grow,” said Gupta. “The UL symbol will look great among the other qualifiers that now stand behind our technology and we expect that it will be a helpful tool for anyone looking to evaluate its use.”
