Armaflex® Rail ZH & ZH-C halogen free foam 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.
Applications include insulation/protection for air-conditioning and refrigeration air ducts and pipes (including elbows, fittings, flanges etc.) to prevent condensation.
Armaflex® Rail foam comes in two grades; either standard ZH or ZH-C which is the standard ZH material but with a silver metallic look coating.
