Armaflex Rail ZH & ZHC

Armaflex® Rail ZH & ZH-C halogen free sponge is the world’s first flexible closed cell insulation to meet EN45545-2 fire protection requirements.

. It is the leading and most innovative closed cell thermal insulation available to the railway industry worldwide and comes complete with a built-in vapour barrier reducing the risk of corrosion under insulation (CUI). Armaflex® Rail ZH & ZH-C has been developed to produce extremely low smoke density and reduce the risk of mold and mildew contributing to an improved indoor air quality.
