Expanding Foam Tape arrives pre-compressed on the roll. Once removed from the roll it will self expand to provide a 600 Pa wind driven rain seal. It is ideal for sealing uneven voids and is most commonly used as a perimeter seal in the installation of windows and doors as well as filling critical joints in timber-framed buildings.
This tape is not a weather seal once expanded beyond 4mm but can be used as a gap / void filler air and dust sealing.
