75mm SIGA Fentrim IS 20 (15/60mm) is a pre‑folded, single‑sided interior sealing tape designed for fast, reliable airtight connection of window and door frames, reveals, and structural junctions on the warm side of the building envelope. It provides durable adhesion on a wide range of substrates and ensures long‑term airtightness in modern insulated constructions. Fentrim IS 20 is engineered specifically for interior airtight sealing at window and door interfaces. The tape is pre‑creased, allowing installers to achieve clean, accurate detailing along frame edges, reveals and connection joints without wrinkles or misalignment.

Its high‑performance acrylic adhesive bonds securely to timber, concrete, masonry, steel, rigid plastics and common interior construction materials. The tape is non‑toxic, solvent‑free, and integrates seamlessly with SIGA’s interior airtightness systems, including vapour control layers such as Majpell 5 and Majpell 25. Fentrim IS 20 delivers fast installation, precise detailing, and long‑term airtightness, making it a trusted choice for interior window and door sealing. Its pre‑folded design and strong adhesive ensure dependable performance even in complex junctions.
