Our Traditional 'Super H' Cowl is designed to ensure that no matter what the wind direction or strength your flue or chimney will be protected from downdraught. As the wind passes down the top of the external parts, it creates a wind flow that exhausts the smoke and fumes out of the lower exits, quite simply brilliant. So powerful is this action of the H Cowl that gusts of wind blowing through the air shafts produce an up-draught equal to about 30% of the velocity of the gusts. In normal weather, the 'Super H' Cowl Cowl possessing four outlets to the atmosphere improves any sluggish updraught. Only the genuine 'Super H' Pot and Cowl has the exclusive design, which converts downdraught into an updraught — no matter how strong or gusty the wind may be. Our superb range of Traditional 'Super H' Cowl are designed for all types of flue and sizes including the appropriate fixing for Chimney Pots, Twin Wall Flue and flexible flue liner fixings.
