Corotherm Grey Flashing Tape - 10m x 225mm

The Corotherm Flashing Tape is a quick, clean and effective way to create a moisture-resistant seal between your polycarbonate roofing sheets and adjoining wall surfaces. Designed as a flexible self-adhesive butyl strip, this flashing tape ensures a watertight connection without the need to cut into the wall or use lead flashing.

Ideal for use with 10mm, 16mm and 25mm Corotherm polycarbonate sheets, this tape is applied directly between the wall and rafter supports before the roof is fixed into place. It conforms easily to different surfaces and provides a strong, weatherproof bond that helps prevent leaks, water ingress and long-term structural issues.

Supplied in a convenient 10m roll, this flashing tape is suitable for a wide range of applications — from lean-tos and carports to conservatories and verandas. Its versatile design makes it ideal for both domestic and commercial roofing projects where dependable sealing is essential.

Whether you’re working on timber, masonry or PVCu, Corotherm Flashing Tape offers fast application, lasting performance and compatibility across multiple substrates.
