Showerband is a waterproof and flexible polyethylene fleece pressure-sensitive adhesive (PSA) tape made with a copolymer of isobutylene and isoprene. This composition enables a wide range of temperature resistance and ensures that the tape does not harden or become brittle over time. Shower trays and upstands at the wall connection joint are typically sealed with a silicone bead to create a waterproof barrier between the upstand and the wall lining. While this method meets code requirements, years of experience have shown that this joint is subject to constant movement due to expansion and contraction from hot and cold conditions in showers.

Building movement and shrinkage also exert pressure on silicone seal joints. Showerband acts as a “belts and braces” protective waterproof band that covers the area between the shower tray and the wall lining, overlaying the silicone joint. This provides a double-layer protective waterproof seal in case of any movement, expansion, or contraction.

Showerband is flexible and designed to withstand both warm and cold temperatures, accommodating movement in these joints to ensure a reliable waterproof seal in this vulnerable area.
