In terms of appearance, this cowl is marginally larger than your usual static down draught cowl, which allows it to be far superior to its counterparts in three key areas:- To work properly a chimney must have draw, both to clear the products of combustion and to provide fresh combustion air to the fire. This is equally true whether the chimney is serving a traditional open fire, a fire-box or a wood or a multifuel or woodburning stove. Colt Cowls supply the largest range of chimney cowls in the UK, and have a reputation for producing the highest quality chimney cowls and chimney birdguard cowls available on the market. TheAnti Downdraught Cowl is not to be used with smokeless fuel.It is recommended using the MAD Junior Stainless Steel or MAD Senior Stainless Steel when in use with more corrosive fuels such as smokeless fuel Made from stainless steel, providing a more durable and long lasting Birdguard when corrosive smokeless fuels are burnt. The nuisance caused by birds, small animals and leaves entering the chimney can be resolved by fitting this cowlThe knowledge and technical support we offer our customers far surpasses that of our competitors, whilst our focus on solving chimney problems with modern designs and the most up to date of aerodynamically shaped products, cements our market dominance. Testament to our claims is that our range is available for all the largest builders’ merchants’ right across the UK along with all major chimney and flue distributors. Very few anti down draught cowls do all three of the above successfully. It is almost impossible to find such an expertly designed and crafted product that can successfully manage all of the above problems – this product does! In recent times we have also reengineered the senior cowl so that the structural integrity will stand up to the biblical weather our country has experienced of late. With three hidden stainless steel straps running across the body of the cowl, bent and formed to provide maximum durability, it is now stronger than those slightly smaller cowls that need less structural integrity. However, it has been designed for both durability and practicality, with a bulbous lid for ease of sweeping. In our opinion this cowl is brilliant in every way! MAD Cowls manufactures 3 different models of static anti-downdraught chimney cowls – the Senior, the Junior, and the MAD. All models have an aerodynamic shape that will divert directional wind across the top of the chimney to draw the smoke out and preventing downdraughts. iii) and lastly (which is common in the most popular of new smaller compact cowls that purport to achieve both of the latter), the senior does not restrict the flow of gases where smaller compact cowls often do. The cast aluminium base is exceptionally free-flowing and offers very low impedance to flue gases. The open body of the cowl has a clearance area greater than the chimney pot cross-sectional area and likewise offers very low impedance to smoke and flue gases. An effect of standard Chinese-hat type cowls which is not often appreciated is the tendency for smoke to ‘bounce’ off the underside of the cap and travel downwards thereafter. To understand the effect, try holding a spoon the right way up under a running tap! In certain conditions, this is enough to send the smoke right down to the ground where it can become a nuisance. By contrast, the Aderyn Cowl simply deflects the smoke, which can continue to rise at all times.

Wind-driven rain normally enters any standard cowl, and this can result in water being funnelled directly down into a stove in the case where a chimney liner is installed, causing rusting or damage to the stove lining. The Aderyn cowl prevents any wind-driven rain entering the chimney, whether in heavy vertical rain or the near horizontal gale-driven showers and squalls that are a common feature of our weather in the UK. The aerodynamic design and quality of the twin sealed bearings ensures that the Aderyn cowl responds instantly to any breeze, protecting the chimney at all times. Because the Aderyn cowl faces away from any wind, a low pressure zone is created on the lee side just above the chimney pot. The result is better chimney function, which reduces the chances of tar and creosote formation that can occur in sluggish flues. Observations have shown that birds do not like the Aderyn cowl. For obvious reasons! In addition, the moving body prevents birds perching and discourages approaches for the purpose of nest-building. The incorporation of swages and strengthening beads on the lid of the MK2, allow for increased structural integrity and durability for longer periods of service.Compact design which allows it to be fitted side by side where space between chimney pots is restricted The nuisance caused by birds, small animals and leaves entering the chimney can be resolved by fitting this cowl.
