Type B Vertical DPC Cavitray

Available in 3 variation(s).

Use
Provides vertical DPC element to existing cavity wall.

Introduction
The Type B semi-rigid vertical cavitray may be introduced into the existing exterior skin of a cavity wall following vertical cutting of the masonry to provide a 4mm slot. The Type B establishes a permanent DPC presence. Addressing this vertical requirement in addition to any horizontal requirement (see Type E) is important where a skin changes status by virtue of an extension being added to an existing structure. Where metal profile links are employed to attach masonry and the existing wall is not cut-out to create T-junction cavity continuity, the Type B approach can introduce DPC integrity. See separate page entry for Cavilinks.
