The Ubbink Screw-Fix Airtight Roof Terminal Seal 150–186mm White 0–55° is a robust sealing solution designed to maintain the airtightness of the building fabric around ventilation penetrations. Suitable for use with Ubbink roof and wall terminals, it provides a secure, weather-resistant seal where larger diameter ducts pass through the roof.

Its adjustable 0–55° design allows the seal to suit a wide range of roof pitches, making it ideal for sloping roof applications. The screw-fix installation method ensures a strong, long-lasting fit, helping to minimise air leakage and support efficient ventilation system performance.
