Cowls

In Short, the function of a cowl is to eliminate downdrafts and allow airflow to move only in one direction and that is upwards. Contrary to popular belief, a cowl does not allow for a poorly designed chimney to function correctly. If your chimney is designed correctly it should render a good draw on its own, then a cowl is fitted to prevent downdrafts and rain water from coming down the flue stack.

Steel Material Options & Environmental Recommendations

MILD STEEL / BLACK

Recommended Environment: Inland areas with low humidity and minimal corrosive exposure. Ideal for dry, non-coastal locations where salt air and extreme weather conditions are not a major concern. Most cost-effective option for standard residential applications.

430 STAINLESS STEEL

Recommended Environment: Low to no salt environments. Suitable for areas with occasional salt exposure but not direct coastal conditions. Offers improved corrosion resistance compared to mild steel while maintaining cost efficiency. Ideal for regions with moderate to no industrial pollution.

304 STAINLESS STEEL

Recommended Environment: Semi coastal environments with moderate salt air exposure. Superior corrosion resistance makes it ideal for coast adjacent towns & cities or industrial areas, and locations with harsher weather conditions. An Premium option for maximum durability and longevity in most environments. For coastal towns & beachfront properties in harsh coastal exposed environments, consider upgrading to 316 stainless steel which contains molybdenum for enhanced salt water resistance & maximum longevity - Manufactured on request.
