WALLTITE RSB

 Smart Choice for Sustainable Construction 

BASF’s latest innovation in closed-cell spray polyurethane foam, WALLTITE® RSB, is designed to meet the growing demand for materials that contribute to decarbonization in construction without compromising performance. Developed to help reduce the environmental footprint of homes and buildings, this HFO-based insulation system contains high levels of recycled and renewable content—delivering a smaller product carbon footprint without sacrificing quality or efficiency. 

Ideal for contractors, architects, and builders, WALLTITE® RSB offers high-performance insulation with third-party verified environmental credentials that support LEED®, EPA recommendations, and public or private green building standards. 

Sustainability at Its Core 

The name says it all: RSB = Recycled, Sustainable, Biobased—three pillars that define both what’s inside the product and the impact it delivers. 

  • Certified Biobased Content within the USDA BioPreferred® Program 
  • UL Solutions Verified for recycled and renewable raw material content 
  • Third-party verified Environmental Product Declaration (EPD) demonstrating reduced embodied carbon 
  • Supports low-carbon and net-zero building mandates including LEED v5, ICC 700 and CALGreen 
  • Produced at facilities using renewable electricity from wind and solar power, supported through Virtual Power Purchase Agreements (VPPAs).  This supports low‑carbon project objectives and helps meet growing client expectations for responsible material sourcing. 

By choosing WALLTITE® RSB, project teams can make measurable progress toward lower embodied carbon, greater energy efficiency, and resilient building envelopes—all key factors in sustainable design.
