Lightweight Modular Flooring System for Rail and Road Vehicles

Our solution for spacious, ergonomic passenger compartments. Lightweight, modular, strong and innovative, COMFLOOR® is already trusted and used by many leading international rail and road vehicle manufacturers. Our design’s unique clamping system ensures quick, easy assembly and installation. The units are maintenance-free and ensure reliable, exceptional performance over at least a 30-year lifetime.

Customized Panels

Thin, durable sandwich panels are designed to fit all floor shapes and dimensional specifications. The rigid sandwich structure provides solid insulation and can optionally be equipped with a fully integrated heating system. Heated and non-heated panels can be combined according to customer choice.

Homogeneous Heat Distribution, Increased Comfort

COMFLOOR® includes an optional panel-integrated heating system. Bonded to the panel’s foam core, the heating system is also customized to match any panel dimensions and specifications.

The panel’s foam core insulates the heating system from the surrounding interfaces while an aluminium layer on top optimizes thermal distribution to the passenger area. COMFLOOR® combines superior thermal comfort with a minimum of energy consumption. Metal cover sheets ensure optimal protection against moisture, scratches, cracks and other mechanical damage. Their smooth panel provides an ideal surface for all types of bonded floor coverings.

System Powering

Heated modules are equipped with quick-to-install connec- tors, simplifying the replacement process in the case of any fu- ture panel exchanges. All electrical wiring is fully integrated into the module.

The system’s power supply can be adapted to voltages supplied by the vehicle’s electrical system – such as 120, 230, 400 and 680 volts AC or DC. The panels can optionally be equipped with temperature sensors and thermostats to control the temperature.
