GGR Supplies DC-PEF06P Double Sided Window Glazing Tape
Best for interior seal of insulated glass and sash alignment. This high-performance double-sided foam tape uses a solvent-based acrylic adhesive for quick stick and strong peel adhesion. The closed-cell polyethylene foam fills gaps and forms a flexible barrier against wind, dust, and moisture, making it suitable for interior glazing work on wood, glass, and aluminum substrates. Choose this if you need a dependable, multipurpose glazing tape that holds components in place during installation and reduces air leakage.
Who it’s for: contractors and DIYers glazing sash windows in homes or light commercial settings. Why selected: it combines fast application with durable sealing properties, simplifying the process of creating a tight interior seal around insulated glazing units. Limitation: its performance depends on proper surface prep and substrate compatibility (glass, wood, aluminum) for optimal adhesion.

This 1/16 inch foam tape features double-sided closed-cell polyethylene with a solvent-based acrylic adhesive designed for bonding with glass, wood, and aluminum. It’s AAMA approved, making it a reliable choice for interior glazing seals and for mounting emblems or nameplates in addition to sealing sash gaps. Choose this if you want a clean, reputable option with established glazing performance.
Who it’s for: installers prioritizing official glazing standards and a cleaner alternative to putty. Why selected: consistent adhesive quality and the AAMA-approved rating support durable interior seals. Limitation: intended primarily for glazing and lightweight mounting; heavier loads or non-standard substrates may require thicker or alternative tapes.

Who it’s for: mobile home owners or renovators seeking a complete replacement window with integrated sealing and mounting features. Why selected: built-in flange and predrilled guidance support easier installation and consistent fit. Limitation: installation specifics note spacing guidelines; improper screw placement can distort flange edges if not followed carefully.
Double-Sided Polyethylene Foam Glazing Tape
This 3/4 inch by 1/16 inch glazing tape is a wide-band interior seal option and is AAMA-certified for window glazing. The closed-cell foam with solvent-based acrylic adhesive provides rapid initial tack and high peel strength on glass, wood, and aluminum.
