SIGA Sicrall 170 - Single‑Sided Airtight Sealing Tape - 170mm x 40m roll - Box of 1 roll
SIGA Sicrall 170 is high‑performance, single‑sided airtight sealing tape designed for large‑area bonding of vapour control layers, membranes and panel joints on the warm side of the building envelope. With its extra‑wide 170 mm format, Sicrall 170 provides secure, durable adhesion over broad overlaps and detailing zones, ensuring long‑term airtightness in timber‑frame, steel‑frame, and low‑energy building constructions. Sicrall 170 is engineered for interior airtightness detailing, particularly where wide membrane overlaps or large bonding surfaces require a stable, reinforced tape. Its strong acrylic adhesive ensures reliable long‑term bonding on smooth and slightly rough substrates, including SIGA vapour control layers such as Majrex.
The tape is non‑toxic, solvent‑free, and designed for clean, efficient installation with SIGA’s airtightness system components. Sicrall 170 provides exceptional coverage, strong long‑term adhesion, and reliable airtightness, making it the preferred choice for large‑area interior sealing tasks. Its wide format and robust construction ensure dependable performance in modern, energy‑efficient buildings.
