CRL Foam Glazing Tape (SKU: 74418X12BL) is a closed-cell polyethylene foam sealant tape engineered for exterior and interior glazing, fenestration, and operable joints. The aggressive acrylic adhesive allows precise placement on curved or irregular surfaces with minimal pressure. Use as a primary or secondary seal where glass repositioning is important before final setting.

Key differentiators and long-tail benefits:

• Self-shimming cellular foam — eliminates shims or spacers for faster, consistent glazing installation
• Patented cellular structure resists water absorption and delivers a long-lived moisture seal
• Non-adhesive face releases cleanly from most surfaces for easy maintenance and reuse
• Maintains flexibility at low temperatures and dimensional stability at high temperatures for reliable exterior performance
• Seals effectively against water, dust, and light — ideal for demountable partitions, louvers, access panels, and operable doors
• ENERGY STAR® qualifying fenestration foam glazing tape — supports energy-efficient window and curtainwall systems

Installation notes: Maintain a minimum of 30% compression for an effective moisture seal. Apply with firm, uniform pressure to a clean, dry surface without stretching (paper liner indicates stretching). Butt-cut corners; do not overlap. Apply a thin bead of approved sealant at intersections after liner removal. Compatible with most sealing and glazing compounds.

Product warning: CRL vinyl foam glazing tape must be compressed to maintain an effective seal. In small lites compression may be applied directly; in most cases use a compression wedge gasket.
