Firestop-814+ and Sound Seal 90 Meet LEED v4 Emission Requirements

Everkem Diversified Products, manufacturer of sealants, adhesives, firestopping products, and electrical chemicals, is pleased to announce that Firestop-814+ Firestopping Sealant and Sound Seal 90 Draft, Smoke, and Acoustical Sound Sealant have been UL tested for emissivity and comply to LEED v4 standards for ‘low emission interior sealants and adhesives applied on site’ per CA Section 01350.

The Leadership in Energy and Environmental Design (LEED) program was established as a rating system to evaluate the environmental performance of a building as well as help to promote a market shift towards a more sustainable design. Today, LEED is the most widely used green building system in the world and covers nearly all building project types. The credit-based system creates a framework wherein project teams create healthy, efficient, and cost-effective buildings by earning points for satisfying specific ‘green’ building criteria.

The LEED system has seen multiple revisions, the most recent of which being LEED v4. The latest version aims to be more specialized and offer an improved user experience. Additionally, its criteria are more stringent, and product claims now require validation via testing by an approved, third-party laboratory.

One component of the LEED rating system is minimizing a major class of indoor pollutants known as Volatile Organic Compounds (VOC’s) found within the built environment. VOC’s are a class of indoor pollutants emitted as gases from certain materials and can be emitted into indoor air from many common building materials like flooring, paint, paint strippers and other solvents, as well as sealants and adhesives.

Many VOC’s can cause short and long-term adverse health effects ranging from simple eye and throat irritation to cancer. Additionally, studies have shown VOC levels can be up to ten times higher indoors than outdoors, regardless of whether the building is located in a rural or industrial area.

“When considering the time we spend indoors – at work, recreation, and especially at home – it becomes apparent that minimizing exposure to volatile organic compounds is essential not only for our comfort but for our health and safety,” Lynch said. “In understanding our caulks, sealants, adhesives, and firestopping products are essential components in building safer and more sustainable buildings, we at Everkem realize it is our responsibility to provide quality, performance-driven products that impact the built and natural environments, and the people who occupy them, in a positive way. To carry out that responsibility, it was obvious that we needed to ensure that our products complied with LEED v4 criteria related to product VOC levels and emissions. Doing so provides our customers and those that work, play, and live in those structures peace of mind when it comes to their safety and environmental impact.”
