InvisiWeep - The almost invisible wall weep

The InvisiWeep is the almost invisible wall weep from Timloc.

This innovative new wall weep can be used in any situation where water must be discharged from an external masonry wall. It is perfect for use with the Timloc cavity tray system, over external lintels and at ground floor level. It has many innovative features that are patent pending, including a Venturi effect outlet tube that reduces water pressure, allowing for optimal drainage.

The InvisiWeep is available in a range of colours including clear, blue/black, black, brown, terracotta, buff, white and grey and can be purchased in pack quantities of 50 or 200.

Peep Weep

The G951 Peep Weep provides an unobtrusive solution to cavity wall drainage requirements. The weep features a mortar key to ensure adhesion to the building fabric and an external rib to aid positioning.
The rib surrounds a 62mm high opening to prevent mortar blockage from within the cavity.
The weep’s protective hood which when fitted “peeps” out from the brick fascia is designed to guard against blockage during installation and stops penetration of wind driven rain.
The exit hole is ample for water drainage but small enough to prevent entry of large insects.

Weep Vent

The Manthorpe G950 Weep Vent is used to drain lintels, cavity trays and to ventilate cavity walls.

The product can be slotted between two bricks and mortared into position. It provides an unobtrusive ventilation point for the cavity behind.

The vent has a baffled grille to prevent the ingress of driving rain and wind whilst incorporating an insect grille and drip lip.

This grille is sized to keep out large insects but is wide enough that it will not be blocked by debris, paint or water droplets.

When used with the Manthorpe range of catchment trays the Weep Vent should be placed in the furthest corner away from the finished roof line.

The Weep Vent should be spaced at no greater than 900mm centres to meet N.H.B.C guidelines, which state, “weep holes are recommended to be sited at every 450mm maximum with at least two per opening above all windows and doors.”
