Sika Achieves Platinum Certification Once Again for NSF/ANSI 347
The standard uses a rigorous point-based system to evaluate membrane performance across several key areas, including product design, manufacturing impacts, durability, corporate governance, and innovation. By addressing the building envelope, NSF/ANSI 347 helps architects and specifiers make educated, data-driven choices for sustainable roofing materials.
NSFS 347 2021 applies to all food businesses in Australia, including:
Understanding NSF/ANSI 347-2021: The Gold Standard for Sustainable Roofing nsfs 347 2021
Focuses on energy efficiency and waste reduction during production.
The building envelope—and the roof in particular—plays a massive role in a structure's overall energy footprint and environmental impact. Historically, assessing the "green" credentials of roofing materials was difficult due to conflicting single-attribute claims, such as a product simply boasting recycled content or reflectivity without accounting for toxic manufacturing footprints or poor durability.
NSF/ANSI 347 is the first American National Standard developed specifically for evaluating and certifying the sustainable attributes of single-ply roofing membranes over their entire life cycle. Unlike generic "green" claims, this standard provides a comprehensive, third-party verified framework for assessing a product's environmental impact from design and manufacturing to installation and end-of-life.
A roof cannot be sustainable if it must be replaced every decade. This section assesses the physical properties, projected service life, and ease of repairability of the membrane. High-performing membranes that maximize building energy efficiency (such as highly reflective "cool roofs" that combat the urban heat island effect) score highly here. 4. Corporate Governance The building envelope—and the roof in particular—plays a
The highest tier, representing maximum innovation, material circularity, and corporate accountability. Why the 2021 Update Matters to the Industry
Depending on the total score achieved, a single-ply membrane is awarded one of four performance tiers: Sustainability Assured for Single Ply Roofing Membranes
. By using a consensus-based approach involving manufacturers, end-users, and regulatory agencies, the standard creates a level playing field. According to the Green Building Initiative
NSFS 347 2021: Understanding Sustainable Single-Ply Roofing Standards Unlike generic "green" claims, this standard provides a
This multi-faceted approach ensures that sustainability is considered from manufacturing to installation, encouraging best practices throughout a product's lifecycle.
Look for the on packaging or the manufacturer’s spec sheet. The mark will include the standard number (347) and year (2021 if updated). You can also search the NSF Certified Sustainable database online.
Manufacturers like Sika Sarnafil have achieved Platinum ratings for their PVC membranes, highlighting a high commitment to environmental stewardship. Conclusion: The Future of Roofing Sustainability
This paper outlines the significance, structure, and impact of , the leading national standard for evaluating the sustainability of single-ply roofing membranes.
