CRL Foam Glazing Tape (SKU: 98814X38GRY) is a closed-cell polyethylene foam sealant tape designed for window and storefront glazing applications. The aggressive acrylic adhesive positions the foam with minimal pressure and adheres well to wood, vinyl, aluminum, and glass. Use it as a primary or secondary exterior glazing sealant where glass repositioning is needed before final setting.

Key differentiators:

• Self-shimming closed-cell foam—no separate shims or spacers required
• Patented cellular foam construction resists water absorption and long-term weathering
• Remains flexible at low temperatures and dimensionally stable at high temperatures
• Non-yellowing, non-staining water-white adhesives for a clean appearance
• Seals effectively against water, dust, and light
• Available in multiple sizes for consistent, accurate application

Installation notes: Maintain a minimum of 30% compression for an effective moisture seal. In small lites, compression can be applied directly when installing glazing stops; for most applications use a compression wedge gasket. Apply with firm, uniform pressure to a clean, dry surface without stretching—the paper liner will indicate if the tape was stretched. Cut and butt tape corners (do not overlap); after liner removal, apply a thin bead of approved sealant at intersections. Compatible with common sealing and glazing compounds.

Certifications & efficiency: CRL is an ENERGY STAR® partner and our fenestration foam glazing tapes carry the ENERGY STAR® seal, supporting energy-efficient window and glazing systems.

Product warning: CRL vinyl foam glazing tape must be compressed (minimum 15%–30%, see installation above) to maintain an effective seal. Use a compression wedge gasket where appropriate.
