SIGA Rissan 150 - Single-Sided Flexible Airtight Sealing Tape - 150 x 25m roll - Box of 4 rolls

SIGA Rissan 150 - Single‑Sided Strongly Adhesive Tape - 150 x 25m roll - Box of 4 rolls

SIGA Rissan 150 is a wide, highly flexible single‑sided sealing tape designed for creating durable airtight seals on membranes, vapour control layers, and penetrations on the warm side of the building envelope. Its 150 width and elastic backing make it ideal for sealing large or irregular areas, curved surfaces, and movement‑prone junctions where standard tapes cannot maintain a reliable airtight bond. Rissan 150 is engineered for interior airtightness detailing, especially around cables, pipes, ducts, junctions, and wide membrane overlaps. The tape’s flexible backing conforms tightly to uneven or curved surfaces without lifting, ensuring a long‑lasting airtight seal.

Its high‑performance acrylic adhesive delivers strong, durable bonding on smooth and slightly rough substrates. Rissan 150 is non‑toxic, solvent‑free, and fully compatible with SIGA membranes such as Majpell 5, Majpell 25 and Majrex 200. Rissan 150 provides exceptional flexibility, wide coverage, and strong long‑term adhesion, making it the preferred tape for sealing large or complex detailing zones. Its ability to conform to irregular shapes ensures airtightness where standard tapes would fail.
