SIGA Wigluv 20/40 - Rainproof Exterior Sealing Tape - 60mm x 25m roll - Box of 10 rolls

SIGA Wigluv 20/40 is a single‑sided, exterior sealing tape designed specifically for tight, narrow detailing zones on roof and facade membranes. Its dual‑width format (20 mm + 40 mm) makes it ideal for small overlaps, membrane edges, window corners, and precision sealing where standard tapes are too wide. SIGA Wigluv 20/40 is a diffusion‑open, weather‑resistant adhesive tape engineered for wind‑tight and rain‑tight sealing of roof underlays and facade membranes. The tape features a split‑width design: one side is 20mm, the other 40mm, allowing installers to seal narrow joints, membrane edges, and complex transitions with exceptional accuracy.

Its high‑performance acrylic adhesive bonds reliably to diffusion‑open membranes, timber, metal, and mineral substrates when used with SIGA Dockskin primer. Wigluv 20/40 remains flexible, UV‑stable, and weatherproof, ensuring long‑term protection against wind and driving rain. This tape is particularly useful in detail zones such as eaves, ridges, valleys, window corners, and penetrations, where standard 60mm or 100mm tapes may be too wide or difficult to position.
