The Stainless Steel Traditional Super H Cowl is designed to ensure that no matter what the wind direction or strength the flue or chimney is 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.

Description

The Traditional ‘Super H’ Cowl is designed to ensure that no matter what the wind direction or strength the flue or chimney is 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.

Stainless Steel Traditional ‘Super H’ Cowl – available sizes above

Why the H Cowl Cures All Downdraught

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.

The ‘Super H’ Cowl cowl should be positioned so that it faces broadside onto the troublesome wind. It should be as exposed and high as possible.

Super H Cowl Variations

Standard Chimney Pot Fitting

The Super H Cowls are designed to fit internally into your Chimney Pot.  If you are fixing your Super H Cowl to a Chimney Pot they can cemented into place.

Due to the size and weight of he Super H Cowl we recommend cementing your Super H Cowl into place when fitting to a Chimney Pot.

If you are fitting into a standard flue pipe they can be self-tapered into place.

Pot Hanging Cowl Fixing (Chimney Liner Fixing)

The Super H Cowl is designed to attach to a flexible flue liner and are attached with Jubilee clips that come with the Super H Cowl.

When ordering the size please base it on the size of the flexible liner it needs to be attached to.

We will also provide a Skirt size of 285mm which will fit fit a standard Chimney Pot.

Twin Wall Fixing

The Super H Cowls are designed to fit to fit internally into a twin wall insulated pipe.

When ordering please order the internal diameter of the twin wall. This will then slot inside and the skirt will cap off the top of your pipe.

The Super H Cowl is then secured with a Jubilee clip. However, preferably use a locking band that should be supplied with your twin wall system.

The following Super H Cowl was recently installed on a customers Chimney in Anglesey.

Both the customer and I are extremely pleased with the results and the installation of the Super H Cowl was extremely straight forward.

In this instance the Super H Cowl was installed with our Chimney Liner Fixing Kit and Skirt. The Cowl was suitable for a 5″ Flue Liner and we supplied a Super H Cowl Skirt which is suitable to cover Chimney Pots up to 285mm.

Finished off with a silicone seal between the Super H Cowl and the Skirt to ensure everything is water tight. I’m sure you will agree this looks great and the skirt ensures that the Chimney is well dressed and water tight.

The principle is exactly the same if you wish to purchase the Super H Cowl for a Twin Wall Flue.

    Just want to say Thank you, I recently ordered an H Cowl to be delivered to Jersey, the efficiency, helpfulness and the speed of delivery was first class.

    So nice to get what you have ordered without any problems or delays and a quality cowl too.

    Kind regards,

    Julie.

    Great response to a delivery issue. Would highly recommend.

  3. Keith S.

    Good value. Quick delivery. Well packaged. Cowl has now been fitted to our chimney but not yet used till the weather is colder.

  4. Mr M.

    I’ve been trying to solve a down draft problem on a twin wall flue for years, trying various expensive spinning and ‘automatic’ cowls with no success. The Super H cowl solved the issue instantly and I wish that I’d tried it first! Delivery was fast, with good communication and rapid answers to my questions. A very positive experience and a highly effective product, thank you.

      Best wishes

Choosing the Correct Size

Its sometimes difficult to choose the correct size of Chimney Cowl. We have the perfect solution and can be done from ground level as well.

If you can accurately guess the size or width of the chimney pot from the floor you can order the right Cap or Cowl from Chimney Cowl Products. The good news is this is relatively easy once you know the rough size of a house brick and the thickness of the walls of a chimney pot.

Using either the naked eye or a set of binoculars get a ‘side on’ view of the chimney pot you wish to cap or fit a chimney cowl, then find a full sized brick nearest to the chosen pot as a reference, normally directly underneath.

Now imagine that the brick is placed on top of the chimney pot itself and make a mental note whether it would fit inside, hang over, or sit flush. It may sound silly but once you know that the width of an average UK house brick is 225mm ( 9″ ) for imperial or 215 ( 8 and half ” ) on a modern property, it provides a very accurate impromptu tape measure.

The other factor you may need is internal pot size, this can also be guessed quite accurately if you know the average thickness of a chimney pot is about 25mm ( 1″ ) , simply factor this in and you can work out most chimney pot width’s quite accurately.

If you have large decorative rolls on top of the pot, make an allowance for this by guessing, using a brick as your guide.
