Siga exterior tapes and membranes

This collection includes SIGA exterior tapes and membranes — high‑performance building products engineered to create airtight, wind‑tight and weather‑resistant building envelopes for walls, roofs and façade assemblies. SIGA’s range of breathable membranes and specialized sealing tapes are used by builders and contractors to protect structures from moisture, drafts and air leakage while allowing controlled moisture vapor diffusion.

Products such as exterior adhesive tapes (e.g., Wigluv®) provide strong, weatherproof sealing of overlaps, joints and penetrations on exterior surfaces, and are designed to remain durable under long‑term exposure to the elements. Complementary facade and wall membranes (e.g., Majvest® series) offer rainproof, wind‑resistant protection while supporting vapor permeability for effective moisture management.

Combined with primers, airtight sealing tapes and accessory products, SIGA exterior solutions help improve energy efficiency, reduce air leakage, enhance insulation performance and contribute to a more durable building envelope.
