K-EXPAND BG1 5–10mm × 5.6m is a self-adhesive, pre-compressed polyurethane expanding foam tape offering dependable joint sealing across a broad range of standard and slightly wider construction tolerances. Compressed to 5–10mm for straightforward, mess-free application and expanding progressively to fill joints up to 26mm wide, this tape is well suited to residential and light commercial window and door installations, composite and timber frame sealing, cavity closer applications, and any perimeter joint where a mid-range expansion profile delivers a secure, weather-tight result.
The 5.6m roll length is tailored to precise yield per opening — providing sufficient material for a full window or door perimeter with minimal off-cuts, making it a cost-efficient choice for both single-unit and multi-unit installation programmes. BBA Approved and verified to DIN 18542 BG1 standards, it provides certified protection against the elements in exposed UK external environments.
