The Type BWVC is a preformed DPC cavitray that vertically connects two levels within the same masonry skin without adversely interrupting bonding or coursing.
Its presence prevents horizontal damp transference. It is extensively used in bay window construction where the level of the roof intersection and that of the support lintel spannng the bay is not shared and seperating courses exist between them.
Type BWVC units are handed and available to suit brickwork / block work coursings. Units are introduced at each end of the lintel and provide permanent DPC connection upwardly to the cavitray at roof intersection level.
To prevent wet external skin masonry at the side of a bay window from conveying dampness inwardly via the unprotected couses separating the higher (Bay Roof) tray arrestment level from the lower (Bay Support) lintel level.
