A working area equipped with a double cloth was built into a shelter located in Hyvinkää thus making it possible to heat the shelter also in winter.
Two door openings were made to the tent, and steel-framed sliding doors were mounted to the openings. They were coated with a PVC cloth on both sides. The usability was expanded even more when veneering was applied to the lower part of the interior walls within the hall to protect them from dents. This way, the interior cloths will last longer.
