The ComforTEK flooring system from Commercial Vehicle Group uses a layer of bonded, flexible polyurethane foam substructure that maximizes thermal properties for improved driver comfort and increased operating economy. With truck engines running hotter to meet emissions requirements, more heat can be transmitted into the cab through the floor; drivers then adjust the HVAC to maintain a comfortable cab environment. ComforTEK is designed to allow the HVAC to perform more efficiently and to maintain cab temperature stability to reduce fuel consumption and maintenance. More than 56 different flooring material combinations were tested during development. The system uses recycled materials and features sound transmission loss performance equal to or greater than standard production flooring.
