Type C Cavitray

Application

For use over common openings.

Description

A preformed, ready shaped horizontal damp proof course (DPC) cavity tray for use over proprietary metal, cast in situ, prestressed and precast lintels.


Features and benefits:

  • Unobstructed cavity compartment area.
  • Supplied in profiles to match appropriate proprietary lintels.
  • Strong, lightweight and puncture-resistant.
  • Suitable for traditional or timber frame construction.
  • Fulfils British Standards and NHBC requirements when used as an independent DPC with proprietary metal lintels in certain locations and applications.
  • Eliminates the danger of misplacement and installation deviances associated with site fabrications using roll materials.
  • Inner skin return: Type C is self-supporting, there is no need to build into the inner skin. However, an inner skin return option is available on request.
