FREE Insect Screen with every 300mm Disused Chimney Cap from Chimney Cowl Products – help protect your Chimney from swarming bees and wasps

Every Disused Chimney Cap comes with Our 7 Year Guarantee.

The C-Cap Chimney Cap is a Robust, High Durable, UV Resistant and has a well-proven record for reliability and faultless performance. This Chimney Cap is designed to fit any standard design round chimney pot, up to 280mm external diameter.

Fitting or removal is simple and takes seconds, requiring no special skills. However, gaining access to pots should only be undertaken by a suitably experienced person using appropriate access equipment.

o Pots need to be in sound condition. Any cracked pot should either be replaced or suitably bound to accept lateral pressure from the retaining spring wires.

o The C-Cap is for use on redundant, disused chimneys only. Care needs to be taken that capping is not carried out to any flue that is still in use. Check it first!

o As with any capping, the flue should preferably be swept clean and any obstruction (e.g. bird’s nests) removed.

o C-Cap has been site-tested over 10 years and in severe gale conditions from Cornwall to the Orkneys.

o Tough, moulded cowl ideally suited to outdoor applications, the C-Cap fits neatly over the chimney pot where it is retained by galvanised steel spring wires.
It can be fitted to any standard round pot up to 280mm diameter and is light enough to allow several to easily be carried up the roof, where fitting to the pot takes a matter of seconds.

o Many thousands of C-Caps are fitted throughout the UK, as far north as the Orkneys, and it is the only cowl for disused chimneys that guarantees 100% protection against rain, snow, gales, birds etc. – in fact everything nature can throw at it.

o All C-Caps are supplied with an optional ‘insect screen’ to provide additional protection against nesting wasps. This can simply be fitted with the C-Cap at the discretion of you, as appropriate.

o Pots need to be in sound condition. Any cracked pot should either be replaced or suitably strapped to allow insertion of the C-Cap retaining wires.

o The unique design of the C-Cap allows continuous, permanent ventilation of the chimney, as recommended by Building Research Establishment (BRE).

The C-Cap Chimney Cap is a Robust, High Durable, UV Resistant and has a well-proven record for reliability and faultless performance. This Chimney Cap is designed to fit any standard design round chimney pot, up to 280mm external diameter.

    The buying experience was simple, and the delivery was as promised, the Chimney Cap was simple to install because of my age I had it fitted by Roofer.
    It will cure my wind noise my previous cowls I had fitted made no difference, so we are looking forward to no wind noise.

    Kind regards

    Good quality produce, easy to install and aesthetically pleasing.

    It could be the answer to my wind noise, since it was fitted we have had no wind but living on top of a Hill overlooking the sea it will soon be put to the test.

    Seems perfect, time will tell.

    The C-Cap 300mm chimney cap is a fantastic product, really robust and took 30 seconds to fit, 2 screws hold the sprung legs in place, they are very robust and a little force is needed to push them into the chimney pot all at the same time, but once all are inside it simply slips into place, the insect mesh is a fantastic addition to this item too.

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.
