K-EXPAND SELF-ADHESIVE PRE-COMPRESSED PU EXPANDING FOAM TAPE BG1 17-32MM X 3M (17-98MM)

K-EXPAND BG1 17–32mm × 3m is a self-adhesive, pre-compressed polyurethane expanding foam tape engineered for heavy-duty joint sealing where maximum gap-filling performance is required. Supplied at a compressed thickness of 17–32mm and capable of expanding to a full 98mm, this is the largest-capacity tape in the K-EXPAND BG1 range — purpose-built for wide movement joints, large structural openings, commercial curtain walling, industrial panel interfaces, and any application where extreme joint widths or building tolerances demand a robust, high-expansion solution.

Despite its substantial gap-filling capability, the tape’s controlled, progressive expansion ensures it remains workable during installation, allowing accurate positioning before it reaches its full 98mm working width. BBA Approved and fully compliant with DIN 18542 BG1 standards, it delivers certified, long-term weather tightness in the most challenging external conditions.
