  • Allows an open continuous ventilated airspace of 44 mm.
  • Exceeds the 38 mm requirement by the Centre for Window and Cladding Technology (CWCT).
  • Quick to install.
  • Polythene sleeved to give weather resistance in a semi-exposed application.
  • Suitable for horizontal and vertical installation.
  • Supplied with two galvanized steel fixing brackets in 1 m lengths, and 'pigtail' screws.
  • Achieves a 60 minute fire rating for ventilated cavities ranging from 60–300 mm.
  • Tested to BS 476-20 and EN 1363-1.

The brackets should be securely mechanically fixed to the internal wall at maximum 500 mm centres using non-combustible fixings. Consult manufacturer's literature for further installation information.
