Our sponge dock seal is mainly designed for refrigerated loading docks where the aim is to prevent cold losses during loading and unloading tasks. Its structure is comprised of high-density polyurethane foam cushions covered in PVC that fully insulate the dock when the vehicle is attached to it. Via this system, the lorry's container is compacted against the sponge cushions, which absorb friction, ensuring a great seal and significant energy and cost savings.
