Our fully seam-welded flues cater for all necessary heat expansion and are designed with all the appropriate load-bearing and wind-resistant supports.

Our team work closely with certified structural engineering companies and can deliver bespoke self-supporting towers containing a specified number of flues.


Ranging from 25mm – 125mm, sample ports can be fitted to all installations and retrofitted to existing flues.


Using thermal breaks or firestop penetrations, our flue achieves ratings of EI 120 / EI 240 tested to EN1366-13.


Bespoke rain cowls can be installed to ensure minimal rainwater ingress.


We utilise the latest 3D software to provide a comprehensive design of our flues for incorporation into site models when required.
