The C-Cap is a revolutionary design of chimney cap which helps minimise heat loss from disused chimney flues. It provides 100% protection of the flue against rain, hail, snow, nesting birds, leaves etc. - protecting it from damage while still allowing ventilation of the flue.
C-Cap is exceptionally easy to fit. It is simply pushed into any round chimney pot up to 11 inches (280mm) external diameter, and held securely in place by two spring wires.
C-Cap blends attractively with the profile of the existing chimney.
The volume of air drawn through a standard ventilator in a blocked up fireplace and escaping to the atmosphere is reduced by 70% when C-Cap is fitted. With a hit-and-miss ventilator, the reduction can be more than 90%.
The C-Cap is supplied inclusive of an 'insect barrier'. This feature is unique to the C-Cap and is designed to prevent access by swarming bees, nesting wasps etc. It is optional whether the insect barrier is included during fitting.
The C-Cap fits any round chimney pot up to 11 inches (280mm) external diameter.
Technical
The C-Cap is a robust, high quality product manufactured from ASA plastic and 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.
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.
The cap is for use on redundant, disused flues only. Care needs to be taken that capping is not carried out to any flue that is still in use. Check it first!
As with any capping, the flue should preferably be swept clean and any obstruction (e.g. bird's nests) removed.
C-Cap has been successfully site-tested in severe gale conditions from Cornwall to the Orkneys.
The spring wires that retain the C-Cap on the pot are fully galvanised and are fixed by an alloy clamp and stainless steel self-tapping screws.
Suitability
Please note the C-Cap is suitable for round standard chimney pots only, if fitted to a crown type pot they will be ineffective and may come loose.
The C Cap comes with the manufacturer’s 5 year guarantee.
Subject to the C-Cap having been used with due care and solely for its intended purpose, should it fail through any manufacturing deficiency during the guarantee period, it will be replaced or its cost refunded to you (at the manufacturer’s discretion).
While the material from which the C-Cap is manufactured is highly uv resistant and is specifically designed for outdoor applications, this guarantee does not cover the possibility of some eventual discolouration by sunlight.
Any refund or replacement will only be issued following return of the cowl to us, or to the manufacturer, for inspection.
Customer Reviews
The King of Disused Chimney Caps The most popular disused chimney cap by a mile. We sell 1000's of them, and for good reason. Rock solid construction, made from Styrosun, they are almost indestructable. We tried smashing one once with a hammer to see if it would break. It did in the end, but only with a massive hit! Recommended. (06/05/2011) fluesystems.com - High Wycombe
happy user The C-Cap is exactly what I needed to cap my redundant flues. They were easy to assemble and installation took seconds. I am very pleased with this product. (08/01/2012) Tom -
Excellent service and very easily fitted. The product was easy to order, was delivered very quickly and was simplicity itself to fit. It matches in well with the existing cowl, seems to be very robust and hopefully will resist the high winds we have recently experienced. (12/12/2012) Alan Gilmore - Gloucester
