Timloc Leaded Stepped Cavity Trays for Brickwork

Installation Advice

  • The core product will suit cavity widths of 50-150mm
  • Weep holes in the starter and corner starter trays can be formed by simply installing purpose made Timloc plastic wall weep units (product 1143/TW1)
  • In areas of severe weather exposure, long continuous runs of cavity trays and/or where particularly porous facing brickwork is used, we strongly recommend that extra weep holes are used at intermediate points along the run of cavity trays
  • Heavier code lead may also need to be specified with flashings, fixed and sealed where they overlap
  • Many components come in left or right handed versions, handing is dictated by the direction of the abutting roof slope
