Noise inside train cabins significantly affects passenger comfort, especially in summer, when systems run at full load and travel demand increases. While many associate rail noise with mechanical systems or external sources, a large portion of unwanted sound is transmitted through cabin surfaces themselves. This highlights the importance of acoustic insulation materials applied directly within train walls.

K-FLEX develops advanced  materials specifically for the rail industry’s acoustic requirements. These materials are installed inside the train’s walls, ceilings, and other architectural elements. 

Their purpose is to absorb and dampen sound waves as they propagate through the cabin structure, reducing both vibration and reverberation in occupied areas.

Unlike solutions aimed at mechanical components, K-FLEX insulation works within the vehicle’s envelope to manage sound transmission paths. This ensures consistent and lasting acoustic performance throughout the train interior.

The result is a quieter, more comfortable environment for passengers. 

As travel demand and expectations for onboard comfort rise, acoustic insulation becomes a key factor in modern rail design.
