C-Cap - Buff

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.
