Description

This Type J2 cavity support and closer from Cavity Trays provides excellent DPC (damp-proof course) support while closing the cavity beneath parapet copings. It also ensures a method for closing the cavity in open eaves and other eaves details.

Parapet structures require a DPC directly under the coping, and the British Standards to BS5628: Part 3 qualifies the process in which it must be supported. This Type J closer satisfies these Standards as well as the NHBC performance standards, chapter 6.1, S4 (c) to (d).

Features & Benefits: Type J2 DPC Cavity Support and Closer 100mm - 2.4m Length

  • uPVC material, Type 4
  • Suitable for use in cavities from 90mm up to and including 100mm
  • Standard length of 2400mm
  • Provides DPC support
  • Closes the cavity
  • Prevents water pooling under coping
  • Satisfies BS 5628 requirement
  • 150mm x 30mm x 2mm/2.5mm purposes

Traditional cavity parapets are typically terminated with copings, under which a DPC is positioned and bedded. The DPC's width must be enough to marginally overhang the width of the parapet masonry. This Type J cavity support has been designed to support the DPC where it spans the cavity and has a standard length of 2400mm, 150mm width and 30mm height. It is suitable for cavities up to 100mm.

Please note:

  • This is an uninsulated Cavity Support and Closer. A Cavity Support and Closer is available with an insulated infill of K-value 0.037W/m°C.

Question:

Does this stop any water getting into the cavity

Answer:

Yes it closes the cavity off once bedded in 

Question:

Can you use this product under aluminium capping for closing off parapet ?

Answer:

The function of the Type J is to support the DPC that is fitted beneath a coping and to prevent it from sagging into the cavity. If you are fitting an aluminium capping onto the parapet wall, it is likely no DPC will be required (so nothing to be supported). If you simply wishes to close/cap the cavity at the top of the wall before fitting the aluminium capping then the Type J could be used to achieve this, but may not be fully necessary.
