K-EXPAND SELF-ADHESIVE PRE-COMPRESSED PU EXPANDING FOAM TAPE BG1 7-12MM X 4.3M (7-35MM)

K-EXPAND BG1 7–12mm × 4.3m is a self-adhesive, pre-compressed polyurethane expanding foam tape designed for confident, reliable joint sealing across one of the most frequently encountered gap ranges in residential and commercial construction. Compressed to 7–12mm for straightforward handling and clean installation, it expands progressively to fill joints up to 35mm wide — a size well matched to standard and slightly wider-than-tolerance window frames, aluminium curtain walling sections, timber and steel door frames, and façade panel perimeters where a solid mid-range seal is needed without resorting to a heavier product.

The 4.3m roll length is calibrated to deliver efficient, low-waste yield for individual window or door openings — ideal for both new build programmes and refurbishment projects where material control per unit matters. BBA Approved and independently verified to DIN 18542 BG1 standards, it provides the specification-grade weather tightness and long-term durability that contractors and site managers rely on.

Key Features

• BBA Certified Performance — British Board of Agrément approved for verified long-term durability, weather tightness, and on-site performance
• BG1 Weather Classification — independently tested to withstand driving rain up to 600 Pa at 25% compression
• 7–12mm Compressed / Expands to 35mm — right-sized for standard-to-wider window, door, and façade perimeter joints
• 4.3m Roll Length — calibrated for efficient per-opening yield on new build and refurbishment programmes
• Self-Adhesive Backing — fast, precise application to aluminium, timber, uPVC, steel, and masonry substrates
• Progressive Expansion — controlled foam expansion allows accurate positioning before the tape reaches full working width
• Permanently Elastic — maintains a continuous, weather-tight seal through thermal movement and building settlement
