The asphalt underlayment tape with self-adhesive joint is designed for laying on wooden formwork or OSB. The tape is distinguished by its low weight while maintaining important properties such as strength and resistance to moisture and dust. Mineral sprinkling prevents materials from sticking together even at high temperatures. It is designed under asphalt shingles, under natural slate and under aluminum folding roofing. Bauder tapes are the only ones recommended for Prefa roofing. The tape also has a self-adhesive longitudinal joint, which provides excellent waterproofing and makes installation much easier.
