To evacuate water from lintels, damp courses and cavity trays of buildings elevating more than 11m from ground level, with exterior walls constructed of non-combustible materials.


The NonCom Beak Weep has been purposefully designed to release penetrating water from lintels and cavity trays installed within the cavity walls of buildings constructed of non-combustible materials and/or exceeding the 11 metre in height regulation directive. The trapezoid design features a discreet hooded discharge outlet offering deflection protection against the increasing wind and rain pressures experienced in high-rise structures. The evacuation outlet has radiused sides so the passage of converging water and particle debris is not impinged but is able to freely spread and discharge.

Manufactured in a zinc-based pressure die-casting and conforming to EN 1774 1997 Standards, this A1 fire-rated perp weep will successfully merge with a range of RAL beak overspray mason and mortar A2 Class colours.

When built into a naturally occurring perp joint, the beak weep emerges discreetly demonstrating superior functionality and minimal visual presence.
