Thor Duct Licensed Manufacturer 2022 v4

Fireduct fire rated ductwork improves the safe operation of heating, ventilation, and air conditioning (HVAC) systems by minimising the chance of fire spread. Effective fire resilient insulation acts as a barrier between ducts, to slow down or prevent the passage of flames and smoke around the building.

Ventilation systems with the requirement for fire protection NEED to be constructed and installed to a high standard and not deviated from the tested method.  It is vitally important to follow both the manufacturing guide as well as the VMS Fireduct Installation Guide provided by the Technical Team at V & MS Ltd.
