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.
