Heritage & Listed Buildings

Cast Iron is commonly found on buildings and homes across the UK from the early 1700s onwards, and many traditional buildings such as churches and cathedrals still retain their original Cast Iron systems – a testament to its quality.

Our comprehensive choice of gutter profiles and pipe sizes makes Cast Iron the perfect option for use in conservation areas as well as on listed buildings. The design variety in our selection of Cast Iron systems accommodates a vast range of period properties and tastes, with options ranging from decorative hoppers to various shapes of downpipe or even bespoke options which can match your building’s existing cast iron system.

Faithfully Retaining the Traditional Look

Our Cast Iron systems are the ideal choice for buildings where the heritage look and feel is of the utmost importance. The Cast Iron range from Yeoman Rainguard doesn’t just ensure that your property retains its heritage characteristics and materials; it can also increase the value of your property by reassuring buyers that a quality, long-lasting system is installed that respects the building’s historic features.

Choice of Colours

Our Cast Iron products are supplied in a grey transit coat ready for onsite painting as standard, however, we can supply pre-finished in black or other colours at a premium.
