We offer electrostatic polyester powder coating across the whole spectrum of RAL colours on both rectangular & spirally wound ductwork. This is sometimes requested to give an aesthetically pleasing finish in areas of high visibility. In other instances it may be specified to give a resilient coating in special environments such as swimming pools.
The application of class ‘O’ foil backed phenolic insulation is used to insulate ‘supply air’ or ‘re-circulation’ ductwork. We have provided this service many times for operating theatre air systems in hospitals throughout the UK.
Fire Rated ductwork is used in kitchen extract systems which must withstand both external & internal fire. The product fully conforms to Method 3, BS9999 2008 & is tested to BS476 pt 24; 1987. This is supplied with the relevant certificate of conformity.
