Seminar: GRP Roof Flashings and Valley Troughs

The seminar covers the use of replacement pre-formed GRP flashing components at the valleys, abutments and verges of slated and tiles pitched roofs.

It specifically addresses:

  • The performance characteristics of GRP and the development of machine-made, pre-formed modern applications for the material.
  • An investigation into the practical issues arising from the use of conventional materials and construction methods.
  • Reviews of good and bad solutions to detailing requirements.
  • An introduction to mortar-free ‘Dry-Fix’ applications to reduce labour time and costs and improve detail longevity.

Who should attend?

Architects, specifiers and housebuilders who are interested in modern, quickly installed weatherproofing components which have no residual scrap value.
