K-EXPAND SELF-ADHESIVE PRE-COMPRESSED PU EXPANDING FOAM TAPE BG1 8-15MM X 3.3M (8-44MM)

K-EXPAND BG1 8–15mm × 3.3m is a self-adhesive, pre-compressed polyurethane expanding foam tape engineered for joint sealing applications that demand a step up in expansion capacity without moving to full heavy-duty product sizes. With a compressed profile of 8–15mm expanding to fill gaps up to 44mm, it sits at the upper end of the mid-range — the ideal choice for wider residential window and door openings, composite door frames with deeper reveals, brick-and-block cavity interfaces, steel frame perimeters, and light commercial applications where joint widths regularly exceed standard tolerances.

The 3.3m roll is specifically proportioned for clean, controlled application on individual openings where a single length covers the full perimeter with minimal waste and no unnecessary joins. Every roll is BBA Approved and verified against DIN 18542 BG1 standards, giving specifiers, main contractors, and fenestration installers the confidence that each joint sealed meets independently certified, long-term weather performance requirements.
