Cowls
In Cambridgeshire’s diverse architectural landscape, from historic Cambridge colleges to Victorian terraces in Ely, chimney cowls play a crucial role in maintaining proper chimney function. As experienced chimney specialists, we often find that cowls are frequently misunderstood and incorrectly specified for local properties.
Understanding Chimney Cowls in Historic Properties
Cambridgeshire’s period properties, particularly those in conservation areas, require special consideration when it comes to chimney terminals. According to the Guild of Master Chimney Sweeps, inappropriate cowl selection is a leading cause of chimney performance issues in heritage buildings.
Common Chimney Problems in East Anglia
Our region’s unique weather patterns and architectural styles present several chimney challenges:
Downdraught Issues
Two distinct types of downdraught affect Cambridgeshire properties:
1. Architectural Downdraught
- Occurs when taller structures within 25 metres affect wind flow
- Common in Cambridge’s historic centre with its varying building heights
- Creates a ‘waterfall effect’ over chimney terminals
- Particularly problematic in conservation areas with protected viewlines
2. Geological Downdraught
- Results from East Anglia’s distinctive flat landscape
- Wind patterns roll across open fenland areas
- Affects properties in exposed locations like Ely and Newmarket
- Can cause significant smoke backup issues
Bird Nesting Challenges
The Cambridgeshire region faces particular challenges with bird nesting:
- Jackdaws and rooks are prevalent in rural areas
- Urban properties attract pigeons, particularly in Cambridge city centre
- Nesting season coincides with reduced chimney use
- Protected species considerations in conservation areas
