This cavity wall weep vent from Timloc is specifically intended for use with standard block, stone or brick external walls of thickness between 100-102.5mm and has been designed for use in any situation where water must be discharged from an external wall such as over external lintels, ground floor slab level drainage, and with the Timloc cavity tray system. The full size of the wall weep vent corresponds with the height of standard brick, block and stonework ensuring a discreet finish when fitted into a masonry wall. The cavity wall weep vent is available in a range of colours including terracotta, buff, brown, clear, white, grey and black allowing you to blend the vent with your brick or mortar colour. The cavity wall weep vent features an integral front grille that prevents large nest building insects from entering the cavity, whilst still guaranteeing a reliable discharge of water and free airflow area of 165mm2 per unit. A Timloc weep extension unit can be added to a cavity wall weep vent to build up longer lengths.
