K-EXPAND SELF-ADHESIVE PRE-COMPRESSED PU EXPANDING FOAM TAPE BG1 10-18MM X 3M (10-53MM)

K-EXPAND BG1 10–18mm × 3m is a self-adhesive, pre-compressed polyurethane expanding foam tape built for medium-to-large joint sealing in demanding construction and fenestration environments. Compressing to just 10–18mm for easy handling, this tape expands progressively to fill joint widths up to 53mm — making it a reliable solution for standard window and door frame perimeters, cavity closers, structural panel joints, and façade movement gaps where a mid-range expansion profile is required.

The tape’s controlled expansion rate allows the installer to position it accurately before the foam reaches full working width, ensuring a clean, gap-free seal without mess or overspill. Fully BBA Approved and compliant with DIN 18542 BG1 standards, it delivers certified weather protection across a wide range of residential and commercial build applications.
