Firemac systems use a flexible fabric, bonded both physically and mechanically onto the duct to give the required fire rating. The fabric is manufactured in the UK and all Firemac systems are tested to BS476:Part 24:1987. This is a highly rigorous test and the performance of all Firemac systems is given in the technical manual.
The outer fabric material is silver grey in appearance, unobtrusive and gives a neat, aesthetically pleasing finish.
