Stego Wrap Vapor Barrier Solutions Digital Binder

LEED ® (Leadership in Energy and Environmental Design ™ ): administered by the U.S. Green Building Council® (USGBC®), LEED green building program is easily the most recognizable certification in the industry and has helped define green building in the United States and beyond. LEED offers a variety of Rating Systems depend ing on project type, including new commercial construction and homes. • LEED v4.1 , Building Design and Construction (LEED v4.1, BD+C)*: New Construction v4.1 MR Credit — Material Ingredients: ° Stego Wrap is the first and only below-slab vapor barrier with an HPD that provides chemical inventory disclosure to the required 1,000ppm threshold. • LEED BD+C : New Construction v4.1 IEQ Credit — Low-Emitting Materials And LEED Residential BD+C**: Single Family v4.1 IEQ Credit — Low-Emitting Products: ° Low-Emitting Materials — Primary system accessories for all Stego barrier products are low-emitting for VOCs (certified Clean Air GOLD). • LEED v4.1 , Residential Building Design and Construction (LEED v4.1, Residential BD+C): Single Family v4.1 SS Credit — Nontoxic Pest Control ° Pango Wrap is a physical termite barrier solution (2 points). • LEED Residential BD+C : Single Family v4.1 IEQ Credit — Radon-Resistant Construction ° Stego products exceed the referenced Indoor airPLUS “capillary break” requirement for radon-resistant new construction system design. Standards, Certifications, and Rating Systems The performance of our barrier solutions, as well as Stego’s commitment and efforts toward material ingre dient transparency, offer project teams more direct opportunity to meet program requirements or advance pathways toward compliance. Included below are common green building standards, certifications, and rating systems, along with specific categories or credits Stego products contribute to. ™ NGBS (National Green Building Standard®)/ICC 700: administered by Home Innovation Research Labs®, NGBS is a green building certification specifically designed for homes and multi-family residential. It was developed in partnership between ASHRAE®, the International Code Council® (ICC), and the National Association of Home Builders® (NAHB). All Stego barrier solutions (StegoHome®, StegoCrawl® Wrap, Pango® Wrap, Stego® Wrap, and Drago® Wrap) are Home Innovation NGBS Green Certified for Resource Efficiency and Indoor Environmental Quality. • NGBS 2020: Enhanced Durability and Reduced Maintenance Section 602.1 Moisture Management — Building Envelope: ° 602.1.1.1 — Stego products exceed the vapor retarder requirement for below concrete slabs (Mandatory). ° 602.1.4.1 — Stego products exceed the vapor retarder minimum over floors of unconditioned, vented crawl spaces (6 Points). ° 602.1.4.2 — Stego products exceed the vapor retarder requirement over floors of conditioned, sealed crawl spaces (Mandatory); and below a concrete slab in crawl space (8 Points). ° 602.1.5 Termite Barrier — Pango Wrap serves as a continuous physical foundation termite barrier (4 points). • NGBS 2020 : Pollutant Control Section 902.3 Radon Reduction Measures: ° 902.3.1.1 Soil-Gas Barriers and Base Course — Stego products exceed soil-gas retarder minimum as part of passive or active radon mitigation systems (Mandatory to 12 Points). *includes New Construction, Core and Shell, Schools, Retail, Healthcare, Data Centers, Hospitality, and Warehouse and Distribution Centers **includes LEED Residential Multi-Family and Multifamily Core and Shell

LBC (Living Building Challenge®): administered by the International Living Future Institute® (ILFI), LBC provides a stringent performance-based framework making it one of the more rigorous green building certification programs available. • LBCv4.0 Materials Petal — Red List ° Stego barrier solutions and key accessories are Red List chemical free.
