Application steps

APPLICATION

  • Space ventilators at 200 mm centres.
  • Take care to ensure the fixing holes are cut accurately with a diameter of between 69-70 mm. If the holes are oversize, the ventilators will not fix securely.
  • The ventilators should be a firm push fit into the fixing holes.
  • Ventilation must be provided for the full length of the eaves and along both sides of the building to create a cross flow ventilation action.
