SELF-SUPPORTING DUCTS - Fire Rated Ductwork

ADVANTAGES

  • Fire rated ducts will guarantee the fire compartmentation
  • Promat fire rated ducts tested according to fully-developed ISO-curve
  • Promat can offer a full range of fire ducts: self-supporting, cladded and wrapped
  • Promat systems can be used as ventilation, pressurisation, smoke extract, kitchen extract, cable, basement and enclosed car park ductwork

Promat self-supporting ducts are independent ducts made of Promat boards PROMATECT®-L500 or DURASTEEL®.

Based on the different configurations, the systems can be used as ventilation, pressurisation, smoke extract, kitchen extract, basement and enclosed car park ductwork.

Promat offers the solution for a Type A (duct that prevent of fire getting inside the duct, fire on the outside of the duct) and Type B (duct that prevent of fire getting outside the duct, fire on inside the duct) ductwork.

All these ductsystems are tested according the BS 476: Part 24: 1987 and are Certified by Exova (Certifire)

Big advantage of self-supporting ducts is the possibility of 1, 2, 3 and 4 sided ductwork, this reduces labour, material and installation heights.

See below tables for different configurations and performance.
