K-EXPAND SELF-ADHESIVE PRE-COMPRESSED PU EXPANDING FOAM TAPE BG1 3-7MM X 8M (3-17MM)

K-EXPAND BG1 3–7mm × 8m is a self-adhesive, pre-compressed polyurethane expanding foam tape offering a practical combination of compact compressed profile and solid expansion performance for everyday construction and fenestration sealing tasks. With a compressed thickness of 3–7mm that expands to seal joints up to 17mm wide, it bridges the gap between the finest-tolerance products in the range and mid-size variants — making it a versatile, all-round choice for standard residential window and door installations, timber frame perimeters, uPVC frame sealing, and light commercial glazing where a neat, reliable joint seal is required without the need for a heavy-duty product.

The 8m roll provides efficient coverage for a full window schedule or multi-frame run without the waste associated with oversized rolls. BBA Approved and compliant with DIN 18542 BG1 standards, it is independently verified for sustained weather tightness in UK external conditions.
