Uses:

  • At the abutment of a flat roof with a cavity wall
  • At the abutment of a lean-to or mono pitch roof with a cavity wall
  • Over concrete ring beams
  • Over airbricks, cavity liners, ducts, meter boxes, etc.
  • Clear cavity widths of between 50mm-150mm

*Product code to suit cavity width. For trays featuring the polystyrene strip mortar barrier insert ‘P’ at the end of the required product code. This may incur additional charge.

  • 150mm high back upstand exceeds minimum requirements
  • Low profile lapped joint between sections allows any length of brick, block, or stone to be used without difficulty
  • Angled section between cavity tray base and rear upstand automatically sheds water to the outer leaf
  • Cavity tray builds into the outer leaf only to speed up installation to allow both inner and outer leaves to be built independently if required
  • Choice of two lengths: 880mm for general use; 460mm to reduce waste when making up a run of cavity tray to the required length
  • System available on request with pre-applied polystyrene strips
  • Polystyrene offers a visual locator of the cavity tray so aiding the installation of post fitted lead work – this may incur additional charge
  • Satisfies all NHBC requirements
  • Manufactured to BS EN ISO 9001 and BS EN ISO 14001
  • Complies with all relevant Building Regulations
  • Meets all relevant British Standards
  • All products are vacuum formed in 2.0mm thick rigid polyethylene – virtually indestructible in normal use.
  • Available in black only.

Horizontal cavity trays
The main cavity tray component. Sections join together by means of a lapped joint, sealed with factory applied butyl mastic tape, to form the main cavity tray run. Water is gathered by the cavity tray and is discharged from the wall through a series of weep holes.

Corner units
Allows the integrity of the main cavity tray run to be maintained when it is necessary to turn a corner on a building. External or internal.

Stopends
Fitted at the start and finish of the cavity tray run to seal off the open ends and prevent water running back into the cavity.

  • Weep holes (1143 or Invisiweep) must be provided every 900mm along the cavity tray run to comply with Building Reg. requirements.
  • Each component fits to the next by means of a lapped joint that is sealed with butyl mastic tape. Surfaces must be clean and dry otherwise a good seal will not be formed.
  • With pre-formed cavity trays such as the System 2000 it is not strictly necessary for the cavity tray to span all the way across the cavity. As long as the cavity tray stands back from the rear face of the external wall and projects back into the cavity far enough to intercept drips falling from the wall ties, then it will perform effectively.
  • To calculate quantities, divide the overall length of the cavity tray run by 830mm. If the calculation does not come to an exact figure, round up to the next whole number. The 410mm length can be used as a make-up piece to reduce waste and cost.
  • If the cavity tray is required to turn a corner, ensure that the correct corner units are ordered.
  • Always order stopends – typical installations require one right hand and one left hand stopend for the start and finish of the run.
  • Always state the clear cavity width when ordering.
