Timloc Invisiweep Concealed Wall Weep Vent – Black | Discreet Cavity Drainage for Masonry Walls
The Timloc Invisiweep offers a modern, discreet solution for draining moisture from cavity walls without disrupting the look of your masonry. Designed to blend seamlessly into the mortar line, this low-visibility weep vent delivers exceptional performance in brickwork, blockwork, and stonework, making it the preferred choice for both residential and commercial projects.
Ideal for use in lintels, cavity tray systems, and at DPC level, the Invisiweep ensures full compliance with UK Building Regulations and NHBC standards. Its tapered profile and external ribs guarantee a tight, secure fit within mortar joints, while the full-height upstand prevents blockage from mortar droppings within the cavity.
