Paul Furnevall
Managing Director



We work out of our 12000sq ft purpose-built workshop, using cutting edge machinery including plasma cutting and autofold technology. This gives us the capacity to handle projects large and small with quick turnaround to suit your requirements.

Machinery and Software

Where design and calculation is done we use external professional designers. All other activities are performed in-house, we produce working drawings, project manage, manufacture and install our products using the latest CAD and duct making machinery and software.

We utilise a complete Ductwork Contractor Production Control System which includes libraries of rectangular, round and oval duct fittings which can be dimensioned and automatically manufactured using CNC controlled machinery. It has a proven track record over 25 years in 70+ countries.

We also utilise a 3D drafting software package that integrates with AutoCAD which provides HVAC, Mechanical, Public Health Fitting and Equipment libraries based on leading manufacturers products. It is used for pricing, procurement and manufacture, reducing our production costs.

Site Installation

We have several professional, experienced installation teams to manage multiple site installations at the same time. With a history of hundreds of commercial construction projects successfully delivered to programme and budget we are confident we can satisfy the needs of your project.

Consultancy and Project Management

We offer the full end-to-end service. Our technical team can advise you on the correct product application to achieve the goals of your project. We can consult with you throughout the project. Our experienced Project Managers will manage the full process of startup, through manufacture, installation and commissioning and post-project support.
