Technical details

  • Thermokynnys is an energy efficient, solid and tidy threshold solution for industry, clean rooms, warehouses and garages.
  • Thermokynnys HD is made of 3 mm thick hot-dip galvanized carbon steel (S235).
  • Thermokynnys HD+ is made of 3 mm thick acid-proof stainless steel (AISI 316).
  • The mountings are made of basic (HD) or stainless (HD+) rebar.
  • EPS or urethane board is used as insulation material.
  • The standard lengths are 2500, 3200, 4500 and 6000 mm. (Special lengths are available by order.)
  • Thermokynnys Heat is an optional electric warming system for both models.
  • Border reinforcement is an optional separate component for Thermokynnys:
    1. A 100 degrees angle makes it easier to finish the installation after casting the concrete.
    2. The same measurements as in the Thermokynnys rebar mountings make this component very rigid to install.
    3. The material options are the same as with Thermokynnys.

  1. The Thermokynnys threshold prevents the cold from the outside from reaching the floor inside and thus saves energy.
  2. A Thermokynnys threshold equipped with Thermokynnys Heat prevents the door seal from freezing and getting stuck even in very demanding conditions.
  3. Thermokynnys Heat may afford significant savings in the cost of the heating. Its functionality and electricity consumption have been measured with a customer's sectional door of a warehouse in harbour conditions in Tornio, Finland. During winter 2018-2019, the consumption was about 630kWh, equaling about 50€ in terms of cost. This means 90% savings compared to traditional solutions.
  4. Thermokynnys protects the underfloor heating pipes near the threshold from freezing.
  5. Thermokynnys holds out well against continuous driving over and stays tidy.
  6. Thermokynnys seals up the boundary surface between the door and the floor.
  7. Thermokynnys is a neat and energy efficient heavy-duty threshold solution for clean indoor spaces, storages and garages.
  8. Thermokynnys is a lightweight complete product which is affordable and easy to install.
  9. Thermokynnys gives a carefully finished look to your garage or hall.

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.
