    (b)   openings in vented roof lights, roof ventilators or vent pipes shall be fitted with ember
          guards made from a mesh or perforated sheet with a maximum aperture of 2 mm,
          made of corrosion-resistant steel, bronze or aluminium.
    (c)   glazed elements in roof lights and skylights may be of polymer provided a grade safety
