WALLTITE® v.5
The Next Generation of Closed-Cell Spray Foam Insulation
WALLTITE® v.5 is a purple, closed-cell spray polyurethane foam (SPF) insulation and air/vapour barrier system designed to deliver outstanding performance, durability, and sustainability. Developed with low Global Warming Potential (GWP) hydrofluoroolefin (HFO) blowing agents, WALLTITE® v.5 represents the next generation of spray foam technology—combining energy efficiency, comfort, and environmental responsibility in one solution.
Why Choose WALLTITE® v.5
Engineered for Energy Efficiency
WALLTITE® v.5 offers superior thermal insulation with a high R-value per inch, helping to reduce conductive heat loss and lower overall energy consumption. Its exceptional air-sealing ability minimizes uncontrolled air leakage, improving building envelope performance and allowing HVAC systems to operate more efficiently.
Comfort and Indoor Air Quality
By creating a continuous, fully adhered air barrier, WALLTITE® v.5 helps regulate indoor temperature, reduce drafts, and maintain consistent comfort throughout the year. The product meets GREENGUARD® and GREENGUARD Gold® Certification standards, confirming low chemical emissions and suitability for environments such as schools, hospitals, and residential homes.
Built for Durability
Minimizing air and moisture movement is key to a long-lasting structure. WALLTITE® v.5 helps manage condensation and moisture accumulation—reducing risks of mold, ice damming, and structural degradation—and contributes to the overall durability of the building envelope.
Precision Application, Professional Quality
Installed exclusively by BASF-qualified professionals, WALLTITE® v.5 applicators receive extensive training and certification through Caliber Quality Assurance Program (QAP). Every installation is backed by a limited BASF product warranty for peace of mind and long-term performance assurance.
Reaches Every Corner
As a spray-applied system, WALLTITE® v.5 expands to fill gaps and irregular shapes—creating a seamless, continuous insulation layer that will not shrink, sag, or settle over time. It’s the ideal choice for hard-to-reach areas where traditional insulation may fall short.
Sustainability and Low Embodied Carbon
BASF creates chemistry for a sustainable future. WALLTITE® v.5 utilizes HFO blowing agent technology that significantly reduces global warming potential compared to traditional HFC-based foams.
By integrating multiple functions—insulation, air barrier, and vapour barrier—into a single system, WALLTITE® v.5 minimizes the need for additional materials, reducing embodied carbon and overall environmental impact.
Contributing to LEED® Certification
WALLTITE® v.5 can contribute toward LEED® points in several categories, including:
- Materials & Resources: Environmental Product Declarations (MRc2) and Material Ingredient Reporting (MRc3)
- Energy & Atmosphere: Optimize Energy Performance (EAc2)
Consult a LEED® Accredited Professional for project-specific opportunities.
Applications
