PUR FILL WF: Window Foam

PUR FILL WF is a custom-formulated, one-component polyurethane foam sealant designed specifically for professional window and door installations. It provides a high-performance seal that stops drafts, improves energy efficiency, and prevents moisture penetration without the risk of damaging sensitive frames.

Key Benefits & Performance

• Minimal Expansion: Engineered to prevent the bowing or moving of window and door frames during application and curing.

• High Thermal Efficiency: Delivers an R-factor of 5.9 to 6.0 per inch, allowing installers to match the thermal performance of the windows being installed.

• Elastic Flexibility: Formulated with elastic merits that provide flexibility during temperature swings, ensuring the seal remains intact.

• Air & Moisture Barrier: The foam cures to form a skin that acts as both a durable air barrier and a defense against moisture penetration.

• Professional Yield: A single can provides approximately 10 dispensed gallons, enough for a 1/2 inch bead over 960 linear feet.
