The C-Cap 350 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 350 is exceptionally easy to fit. It is simply pushed into any round chimney pot up to 13 inches (330mm) 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 350 is not supplied with an 'insect barrier'.
The C-Cap 350 fits any round chimney pot up to 13 inches (330mm) external diameter.
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 350mm 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.
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.
Simple and easy Purchased 2 of these caps to fit onto the octagonal chimney pots on my house which were 260mm internal diameter and over 310mm outside diameter. Very easy to fit. good quick service from the website.
