Please note, this is an insulated Cavity Support and Closer. Click here for the uninsulated equivalent.

Parapet construction requires a DPC immediately under the coping. BS5628:Part 3 qualifies the manner in which the DPC must be supported. The Type J closer fulfils the requirements of the British Standard, and also the N.H.B.C. performance standard, chapter 6.1, S4 (c) to (d). The conventional cavity parapet is normally terminated with copings, under which a DPC is bedded and positioned. The width of the DPC must be sufficient to slightly overhang the width of the parapet masonry. Support of the DPC is required where it crosses the cavity.
