Design & Installation

Our flexible approach to flue design and installation has enabled us to undertake projects ranging from conventional, freestanding mild steel chimneys, to specialised flue dilution systems where a chimney is not practical.

Each project is examined closely by our in house design team and all design and emission calculations are made using our FlueCalc software, ensuring that we are able to offer a fully-designed solution at the time of initial quotation, giving our clients the design and competitive edge in the market place at the out set.
