Planning policy
The material properties of cast iron have long been recognised and it is these which make it particularly suitable for the rainwater systems of listed buildings and wherever conservation is an issue.
In its Planning Policy Guidance (PPG 15), the Department of the Environment, Transport and the Regions, Department of National Heritage, acknowledges the importance of specifying cast iron replacement of the rainwater systems on such buildings of historical significance.
No other material can match the character, durability, strength or appeal of cast iron and – most importantly – only cast iron can preserve the intentions of the original architect and the aesthetic integrity of the building.
Strength
- High resistance to impact (accidental and vandalism) a major consideration for inner cities, town shopping precincts and schools etc
- Secure against – heavy snow falls and high winds
- Rigidity to comfortably accommodate the weight of ladders for routine maintenance
- The physical properties of cast iron will be sustained throughout its life (provided adequately painted and maintained)
Quiet/noiseless
- Will not rattle in high winds
- Will not twist/creak due to temperature changes
- Excellent sound deadening properties – therefore no significant sound of running or dripping water disturbing the peace
Appearance
- Cast iron has aesthetic charm that simply cannot be matched by other materials
- Retains and enhances the traditional character of the building
- Can be painted any colour to match building
- Enhances perception of the value to the property
- Many profiles to match virtually all architectural styles
Longevity
- Naturally durable up to 100 years
- Cost effective in long term
- Minimal maintenance: If installed correctly to the manufacturer’s recommendations (- refer to Installation Guide), cast iron systems should require little structural maintenance throughout their life only periodical painting approximately every 5 years or longer (depending on location and climatic conditions)
- Eliminates unnecessary replacement and waste
- Profile designs have changed little over the years. Therefore new components can easily be integrated into existing systems, avoiding costs of complete replacement
- 100% RECYCLABLE
