Introduction

DPCs, lintel and cavity tray installations require weeps to discharge collected water from the building fabric. Ventilating of wall cavities, and enveloped construction is also necessary to avoid interstitial condensation.

Type W Caviweeps/Cavivents ensure water is removed from the building whilst also encouraging the wall to breathe. Being dual-functioned, the Type W takes advantage of the pressure differentials which exist in and out of the cavity. This aids evacuation of cavity humid air. The NHBC standards (4.4c.111) advise that the cavity below DPC level and at eaves and verge level should be ventilated. This requirement is fulfilled using Type W weepvents.

Use

Dual-purpose perp weepvent.
