About us

John J Doyle Ltd is Ireland’s leading expert in two areas: the design, supply and installation of chimney systems and refractory engineering services.

Founded in 1928 by the grandfather of the current managing director, John J Doyle Ltd has earned its reputation as Ireland’s leading firm of refractory engineers in Ireland, based in Great Patrick Street, Belfast. As a family organization, we pride ourselves on our long association with the highest quality refractory work. The combination of vast industrial experience, attention to detail, commitment to innovative technology and customer service has placed the company at the forefront of the industry. Specialist teams work to the highest standards to obtain the optimum life and performance from all products and installations. In addition to servicing traditional industrial sectors, John J Doyle Ltd. services the specialist needs of the aluminium, cement, petrochemical and waste incineration industries.

Over time, we have applied our skills and experience to support Ireland’s manufacturing sector through providing industrial chimney solutions, which in turn has also supported the considerable growth within the domestic chimney flues market with the increased popularity of stoves and condensing boilers.

However, we have also had to look for innovative solutions to ensure that our customers are able to comply with increased legislation in terms of quality, CE ratings and building regulations. We are able to supply and install innovative solutions to multiple boiler apartment blocks to comply with legislation and to give complete peace of mind, all the domestic flue and liner products that John J Doyle Ltd stock have full CE approval.
