SIGA Fentrim 20 200mm (15/185mm) is a pre‑folded, single‑sided airtight sealing tape designed for fast, reliable interior sealing of window and door frames, junctions, and structural connections. Its split‑width format allows clean detailing on both the frame and adjacent building components, ensuring long‑term airtightness in modern insulated constructions. Fentrim 20 is engineered for interior airtightness at window and door interfaces, where precise detailing is essential. The tape is pre‑creased, enabling quick and accurate installation along frame edges, reveals, and connection joints.

Its high‑performance acrylic adhesive ensures durable bonding on a wide range of substrates, including timber, concrete, masonry, steel and rigid plastics. The tape is non‑toxic, solvent‑free, and fully compatible with SIGA airtightness membranes and vapour control layers such as Majpell and Majrex. Fentrim 20 offers fast installation, precise detailing, and long‑term airtightness, making it a preferred choice for interior window and door sealing. Its pre‑folded design and strong adhesive ensure reliable performance even in complex junctions.

  • Split‑width 15/185mm format - ideal for bonding both the frame and adjacent building components.
  • Strong acrylic adhesive - ensures durable, airtight bonding on multiple substrates.

  • Non‑toxic & solvent‑free - safe for installers and occupants.
  • Compatible with SIGA membranes - ideal for interior airtightness systems.
