50mm SIGA Nail Sealing Tape - Rainproof Sealing of Nail Penetrations - 30m roll - Box of 10

50mm SIGA Nail Sealing Tape is a high‑performance exterior sealing tape designed to create nail‑tight, wind‑tight and rain‑tight connections under counter‑battens on pitched roofs. It protects roof membranes from water ingress at fixing points and ensures long‑term weather resistance in modern roof assemblies. SIGA Nail Sealing Tape is a single‑sided, diffusion‑open sealing tape engineered specifically for sealing nail and screw penetrations when installing counter‑battens over roof underlays such as Majcoat membranes.

When applied beneath battens, the tape forms a flexible, watertight gasket around each fixing, preventing driving rain, meltwater, and wind pressure from penetrating the roof build‑up. Its high‑performance acrylic adhesive bonds securely to diffusion‑open membranes and timber, ensuring reliable long‑term performance. The tape remains UV‑stable, weather‑resistant, and flexible, even in cold temperatures, making it suitable for year‑round installation.
