Siegware

OMEGA PLASTO is a highly malleable expandable butyl-rubber tape with a fleece base that can be plastered and painted over. The adhesive area has a split, asymmetrical PE backing. The liner split enables precise application at intersections and in corner areas. 

In addition to various sealing applications, PLASTO tape is used to make a second drainage level below the window sill.
