CRL Foam Glazing Tape is a closed-cell polyethylene foam glazing sealant in tape form. Its aggressive acrylic adhesive positions the foam on curved or irregular surfaces with minimal pressure and adheres to wood, vinyl, aluminum, and glass. Use it as an exterior glazing sealant when glass repositioning is important before final setting. CRL Foam Glazing Tape is engineered as a primary or secondary seal in many glazing systems. The tape is self-shimming—eliminating the need for separate shims or spacers—and is built from a patented cellular foam structure that resists weathering and water absorption for a durable, long-lived seal. CRL foam glazing tape with adhesive on two sides – key features:

• Simplicity: no clean-up, easy handling, no mixing or special application equipment required
• Preformed tape ensures consistent, accurate application; no shim required
• Remains flexible at low temperatures and dimensionally stable at high temperatures
• Non-yellowing, non-staining water‑white adhesives for a clean appearance
• Superior resistance to weathering, oxidation, and ultraviolet exposure
• Effectively seals against water, dust, and light
• Available in a variety of sizes

A minimum of 30% compression must be maintained to provide an effective moisture seal. In small lites, this may be achieved by applying pressure directly to the glazing tape when installing glazing stops; in most lites a compression wedge gasket is recommended. Apply with firm, uniform pressure to a clean, dry surface without stretching (the paper liner indicates if the tape has been stretched). Cut and butt tape corners together rather than overlapping or radiusing, and apply a thin bead of an approved sealant at intersections after the liner has been removed. In-service temperature range is –40° to 180° (–40° to 82°C). CRL Foam Glazing Tape is compatible with other sealing and glazing compounds. ENERGY STAR® – CRL is an ENERGY STAR® partner, and our fenestration foam glazing tapes carry the ENERGY STAR® seal, helping improve energy efficiency in fenestration systems. Product Warning:
CRL Vinyl Foam Glazing Tape must be compressed 15 percent to maintain an effective seal. In small lites, this may be achieved by applying pressure directly to the glazing tape when installing glazing stops. In most lites, the use of a
