We are excited to share that as of April 26, 2024, both our Si-COAT® 460RC™ and Si-COAT® 461RC™, manufactured at our Guelph, Ontario facility, have been certified by NSF. This certification, in accordance with Protocol P151 – Health Effects from Rainwater Catchment System Components, assures our stakeholders of the safety and quality of our products, further enhancing their trust in CSL.
NSF Protocol 151 (P151) Certification is crucial for rainwater catchment system components, especially when it comes to roof coatings. Check out our full list of certifications for our Si-COAT® RC™ Series of Products.
- 1. Scope and Purpose:
- P151 covers gutters, barrier materials, and catchment surfaces (such as coatings, paints, lining, and liners) that directly contact rainwater collected for drinking
- Its purpose is to assess contaminant concentrations extracted from these surfaces and components, ensuring they don’t exceed known drinking water maximum contaminants or health advisories.
- 2. Certification Assurance:
- P151 certification provides assurance to public health officials and consumers.
- For roof coatings, it confirms that no components are lost over time and that physical properties are retained during aging.
- Building owners can trust that their roofing system won’t contribute to contamination or waste into rainwater runoff.
- 3. Safe Rainwater Collection:
- P151 ensures that rainwater catchment products do not contaminate the water.
- Components certified under P151 are safe for use in rainwater collection systems and potable water applications.
In summary, NSF P151 Certification plays a vital role in maintaining water quality and safety in rainwater catchment systems, including those with roof coatings but more importantly aligns with CSL’s sustainability initiatives and our commitment to the environment where we live, play and work.
