Intertape Polymer Group 5518USW White Sheathing Tape

Product Description

The INTERTAPE POLYMER GROUP 5518USW is a white polypropylene film sheathing tape with an aggressive solvent-based acrylic pressure-sensitive adhesive. It is designed for permanent seaming and sealing applications in residential and light commercial construction. The tape measures 1.89 inches wide and 55 yards long per roll. Its flexible polypropylene film conforms to irregular surfaces, and the acrylic adhesive maintains a strong bond across a wide temperature range, from -40 degrees F up to elevated service temperatures. Installers in insulation, weatherization, and building envelope work rely on this tape for reliable, long-term adhesion without primer or additional surface prep on clean, dry substrates.

This tape is suited for sealing joints in foam board insulation and other rigid sheathing materials, securing lap edges in house wraps and vapor barriers, repairing rips and tears in roll and batt insulation, and sealing construction films and membranes. It is also used to eliminate air infiltration and drafts around window and door openings during rough framing and weatherization work. The tape is resistant to mold growth and high humidity, making it appropriate for exterior wall assemblies and below-grade applications where moisture exposure is expected.

Key Features

• Aggressive acrylic pressure-sensitive adhesive bonds to foam insulation, house wrap, and sheathing surfaces
• Flexible polypropylene film conforms to irregular and uneven surfaces
• Rated for use in temperatures as low as -40 degrees F and at elevated temperatures
• Resistant to mold growth and high humidity
• Repairs rips and tears in batt insulation, construction films, and membranes
• Eliminates drafts at window and door rough openings when applied to clean, dry surfaces

Compatibility

Designed for use with foam board insulation, rigid sheathing, house wraps, vapor barriers, roll and batt insulation, and construction films and membranes. Do not apply to wet surfaces, wet facing, or wet wood substrates.

Installation Notes

This tape is typically applied by insulation contractors, weatherization crews, and general construction trades during building envelope work. Surfaces must be clean, dry, and free of dust or loose material before application for full adhesive contact. Pressure should be applied across the full tape width after placement to ensure proper bond. Follow applicable building code requirements, including energy code provisions for air and vapor barrier continuity.
