Dupont 197711 Window Door Foam Sealant 20 Oz

Product Description

The DUPONT 197711 is a minimal-expanding polyurethane foam sealant engineered for sealing and insulating around windows, doors, and their rough openings. Its low-pressure build formula prevents frame distortion during application, making it suitable for use around pre-hung doors and framed window units where excess expansion could cause alignment issues. The foam cures to a durable, airtight, and water-resistant seal that helps reduce air infiltration and improve thermal performance. Installers working on new construction and retrofit projects rely on this product to close gaps between frames and rough openings cleanly and efficiently.

This foam sealant is used in residential and light commercial construction and weatherization applications. It is appropriate for sealing the perimeter gap between window or door frames and the surrounding framing or masonry rough opening. Weatherization contractors, carpenters, and general contractors commonly apply it during window and door installation or replacement. It is dispensed via a straw applicator, allowing controlled placement in narrow or deep cavities without full can investment in a gun-style applicator system.

Key Features

• Minimal-expanding formula with low-pressure build prevents frame bowing or misalignment
• Cures to an airtight and water-resistant seal for improved energy efficiency
• Fills, seals, and insulates gaps around window and door rough openings in one step
• Straw applicator included for precise placement in tight or deep gaps
• 20 oz canister provides substantial yield per unit for production installs

Compatibility

Designed as a general-purpose gap-fill and air-sealing foam for residential and light commercial window and door rough opening applications.

Installation Notes

Apply in accordance with window and door manufacturer installation guidelines and applicable building energy codes. Shake the canister thoroughly before use and apply foam in layers for gaps exceeding standard fill depth, allowing each pass to tack before adding more. Wear gloves and eye protection, as uncured polyurethane foam bonds aggressively to skin and surfaces. Keep the area ventilated during application.
