K-FLEX ST DUCT KRAFT

Closed cell elastomeric insulation product free of halogens, PVC, CFC, HCFC and formaldehyde (K-FLEX ECO) covered with a protective aluminum film reinforced with a fiberglass mesh specially designed for marine applications. K-FLEX ECO ALU NET, formulated and produced without halogens, is the concrete answer for limiting energy consumption while respecting the environment. The composition of K-FLEX ECO ALU NET makes the fumes that could develop in the event of a fire, not very opaque and not very aggressive. The ALU NET film with aluminum structure reinforced with a fiberglass mesh, gives the K-FLEX ECO insulating product an additional and very high barrier to the penetration of water vapor, allowing the system, if correctly installed, to maintain performance for a long time. At the same time, it gives good mechanical protection to surface damage, to the action of marine and atmospheric agents, allowing an easy installation and maintenance.
