Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make a cast iron rainwater system an ideal choice for both traditional and modern installations.

The Cast Iron Louvre Airbrick suits Victorian and Edwardian terraced housing, semi-detached properties, public houses, agricultural buildings, and workshop structures where the original airbrick was a louvre-face grille. The horizontal fin profile is widely found in British domestic and light industrial construction from the 1870s through to the 1950s.
