Uponor AquaSAFE™ First PEX Fire Sprinkler System to Receive Exposed Listing

June 2, 2015

A recent update to Uponor’s listing to UL 1821, Thermoplastic Sprinkler Pipe and Fittings for Fire Protection Service, now approves Uponor AquaSAFE™ residential fire sprinkler systems for use in exposed applications. The updated listing approves (with certain limitations) the use of flexible Uponor AquaPEX® tubing and ProPEX® expansion fittings in unfinished basements with dimensional lumber, engineered wood or wood I-joists in accordance with the National Fire Protection Association (NFPA) 13D standard. “Many builders are now installing fire sprinklers to address the International Residential Code requirements for protection of lightweight construction,” says Eric Skare, product manager, Fire Safety. “With this new listing, an Uponor AquaSAFE system now provides the ideal solution for these unfinished basement applications.”
