HP5 | Window & Door Low-Pressure Gun Foam

Origin Pro™ HP5 is a professional-grade, low-pressure, one-component polyurethane foam sealant designed to fill, seal, and insulate gaps and penetrations in the building envelope. HP5 expands to seal irregular voids, helping reduce air infiltration while improving energy efficiency and moisture control.

HP5 cures to a closed-cell foam that is rigid, durable, and dimensionally stable. Once cured, the foam is non-toxic and inert, making it suitable for a wide range of residential and commercial construction applications.

Product Type: One-Component Foam (OCF)
Chemistry: Polyurethane

APPLICATION INSTRUCTIONS

Surfaces must be clean, dry, and free of dust, grease, loose particles, or mold release agents.

For best results, condition the product to 65–80°F (18–27°C) before use.

Attach the container to a compatible dispensing gun, shake well, and begin dispensing. Foam output may be controlled by the trigger and/or metering screw on the gun.

Foam application may be interrupted as needed. As long as the gun remains attached to a pressurized container, it will be ready for immediate re-use.

Replace empty containers with a new container.
