Denso^® 450^mm Flashing Tape: 18" Flashband Tape - High quality, self adhesive flashing tape, for general repairs and sealing. 18" Builders Flashband Tape is a lead coloured, crease resistant flashing tape with a smooth grey covering, with a high grade bitumen backing. Looks like lead, but easier to apply; Interleaved for easy handling. 18" Denso Flashband tape has an aluminium foil laminate embedded within the bitumen layers to give greater puncture resistance, improved tensile strength, elongation and tear strength. This offers the user a stronger tape that is easier to apply and accommodates the natural movement of joints, in service, without the loss of adhesion or splitting. 450^mm Denso Flashing Tape is a robust Domestic & Commercial Building Product that will last for many years, so you can confidently use this flashing to make new or repair old flashings & soakers in brickwork, and use wider Flashband Tape for valley gutters.
