Durasteel® Technical Data
Composite insulation board
DURASTEEL® consists of a calcium silicate core reinforced on both sides with perforated galvanised steel covering sheets.
The punched lugs in the steel sheets are pressed into the core board giving the DURASTEEL® composite board a very high mechanical strength once the drying process is finished.
DURASTEEL® comes in two thicknesses and the material is classified as class A1, non-combustible.
