V-Force Vapor Barriers

Reliable Performance. Proven Results.

V-Force is an impermeable, self-adhered vapor barrier featuring a tri-woven polyethylene facer and SBS-based adhesive. Engineered for performance and durability, this vapor control membrane offers trusted protection in a wide range of commercial roofing applications. Note, V-Force requires primer on all substrates with the exception of steel decks. 

Features & Benefits

• Impermeable vapor barrier with high vapor resistance
• Strong adhesion
• Tri-woven polyethylene facer provides temporary UV resistance and weather protection for up to 90 days
• High tensile strength and elongation make the membrane suitable for applications directly to the steel deck reducing the risk for tears caused by foot traffic, static loading, and dynamic impacts.
• Installs down to 25°F and rising
• Meets ASTM D 1970, Self-Sealing
• Enhanced slip-resistance
  
  

Faster Installations. Fire-Rated Performance.
V-Force FR is a premium, impermeable, self-adhered vapor barrier designed to increase installation efficiency while meeting stringent fire requirements. Featuring an innovative acrylic adhesive and polypropylene facer, this vapor control membrane can achieve a FM Class 1 fire rating direct to steel without the need for a non-combustible separator. V-Force FR does not require primer* making it faster and easier to install compared to traditional V-Force.

Features & Benefits

• Impermeable vapor barrier with high vapor resistance
• The FM Class 1 rating for direct-to-steel applications (mechanically attached and Invisiweld only) eliminates the need for a non-combustible separation layer, such as gypsum, thereby reducing labor and costs on the job.
• Acrylic adhesive technology provides outstanding adhesion with primer-free* installation, saving time and labor
• Wider width (5') reduces the number of seams by 25% compared to traditional V-Force
• Polypropylene facer provides temporary UV resistance and weather protection for up to 180 days
• High tensile strength and elongation make the membrane suitable for applications directly to the steel deck, reducing the risk for tears caused by foot traffic, static loading, and dynamic impacts.
• Expanded installation window down to 20°F and rising
• Meets ASTM D 1970, Self-Sealing

*Primer-free applications on approved substrates.  Some specific project conditions may require use of primer. Please reference the Technical Information Sheet (TIS) for more information and for conditions not covered in the TIS, please reach out to your Regional Technical Coordinator.
