Conservation Vent Grille

£120.00£190.00

Conservation ventilation grilles are cast iron, cowled vents ideally suited for authentic ventilation and extraction of stale air in listed buildings, bathrooms, cloakrooms, tumble dryer outlets and all outlets and inlets where either a 4″ (103mm), 5″ (125mm) or 6″ (150mm) ducting is used.

Choose the size of the grille that is suitable for your requirements (check product specification table below for further details). Finished in a hard-wearing black gloss  or in a red oxide primer ready for you to apply your own finish. The painted black version can be repainted from time to time although many customers allow it to develop a “weathered patina” which is most agreeable for any listed building or period property. – examples shown in the photos on the left .

For larger orders we can supply conservation vents in any RAL colour, professionally primed with 3 part epoxy 2 part gloss or matt top coat at an additional cost – please email item number, quantity and RAL number for a proforma cost for this. We can also supply bare metal for customers to finish on site or to allow to rust for an industrial or contemporary look – to order these please buy the red oxide primed version on this website and stipulate in the comments box that you want them – “bare metal unprimed”

Conservation cowled vents are ideal for deflecting exhausted air downwards and preventing back draughts in prevailing wind positions. They can also be used with a fly mesh, at an additional cost, supplied as an oversize round disc that fits around the end of the spigot.

The external dimensions of the CON4 and CON5 are similar, the difference is the spigot on the back which is either 4″ or 5″ diameter respectively. The CON6 is a completely different casting and weighs a substantial 5KG so, although ideal for larger ventilation and extraction requirements it does need careful and thoughtful installation to ensure it is firmly fixed (it has larger 6mm dia securing holes and longer 35mm spigot length to help with this).

The cast iron Conservation Vent is exclusive to The Cast Iron Air Brick Company and in its ten years of production is now ventilating some of the nations finest period properties (and a growing number of contemporary ones too). It has, and always will be, made in England, proudly displaying the fact along it’s leading edge.

The conservation vent isn’t supplied with mesh, if you want mesh don’t forget to … Purchase mesh seperately here.
