The designer of the Thermokynnys threshold is an experienced professional in the construction business. While visiting building sites he noticed a shortcoming in the implementation of doors an thresholds in garages and indsutrial halls. In these premises the concrete floor usually extends outside the door and is typically reinforced by an angled carbon steel profile at the edge. This kind of a solution consumes a lot of energy and, after some time, it often becomes very untidy due to the rusting of the profile and the cracking of the concrete.

Thus there was a need for a neat, energy efficient and finished threshold solution in the market, and Thermokynnys was designed to fill this gap. Thw first prototypes of the product were made for the designer's own garage.

The company Thermokynnys Oy was founded in 2016 to manufacture and sell insulated HD (heavy-duty) thresholds for garages and industrial halls.
