Application

  • Suitable for all masonry wall applications including residential, commercial and multi storey buildings. It can be site formed into a built-in or surface fixed cavity tray to manage the downward passage of water in cavity wall applications.
  • Suitable for installation in external cavity walls with a masonry outer leaf, including walls with a light gauge steel frame, structural timber frame or masonry inner leaf.
  • Suitable for use to prevent harmful volatile organic compounds (VOCs) and hazardous ground gases from entering into the cavity from the ground or entering the building via internal walls. Also suitable for use on NHBC Amber 1 and 2 sites or where radon gas exists. Can be used on sleeper walls below a ground floor construction e.g. beam and block floor system.

Description
