K-FLEX SRC ECO is an insulating sheet comprising a layer of closed cell elastomeric foam and a protective outer jacket. The special K-FLEX SRC ECO configuration offers a unique product which, in case of fire, retards the emission of smoke and fumes which are also free of hydrohalic acids and organochlorine compounds.

K-FLEX SRC ECO sheets are ideal for thermal and acoustic insulation of walls and technical installations where low smoke emission is required in case of fire.

K-FLEX SRC ECO sheet has been tested according to the current European standard EN 13501-1, for fire resistance of construction products, and has been classified B-s2, d0.

The main advantages of K-FLEX SRC ECO are:
• No halogen in the composition or expansion of the elastomeric material.
• No smoke containing hydrohalic acids and organochlorine compounds in case of fire.
• Retarded ignition of the flame.
• Retarded flame propagation.
• Reduced emission of smoke.
• Low thermal conductivity.
• Higher mechanical properties eith rescpet to an uncoated elastomeric insulation foam.
• Quick and easy installation.
