K-FLEX SRC’s innovative design combines the high thermal performance of a rubber based flexible elastomeric foam with the reduced smoke emission coating, offering a product which is also suitable along escape routes.

K-FLEX SRC sheet is ideal for thermal insulation of pipes, ducting and technical systems in public buildings, including escape routes.

K-FLEX SRC 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 are:
• Retarded ignition of the flame. 
• Reduced flame propagation.
• Low thermal conductivity.
• High resistance to water vapour diffusion.
• Wide range of operating temperatures.
• Consistent performance.
• Higher mechanical properties with respect to uncoated elastomeric insulation.
• Quick and easy installation.
