Triotherm - the Innovative Solution for Windows & Doors

Triotherm, a patented product by Meesenburg GmbH & Co. KG in Flensburg, Germany, was originally developed to optimize the installation of windows and doors within the insulation layer. While it has become a proven method on the continent, in Ireland and the United Kingdom, Triotherm is primarily used as an insulated threshold beneath doors and floor-to-ceiling windows.

 

What is Triotherm? Triotherm is made from pure EPS (expanded polystyrene) with a density of 150 kilograms per cubic meter. This special material allows for necessary load distribution while ensuring a thermally efficient execution of the door upstand.

 

Advantages of Triotherm as door upstand:

  • Optimal Thermal Performance: Triotherm has the same thermal performance as standard mineral wool insulation. This approach avoids thermal bridges and ensures optimal heat retention at floor level.
  • Structural Support: Triotherm transfers the load of the door right into the building structure.
  • User-Friendly: Triotherm simplifies the connection details between windows, doors, and the floor.
  • Easy & Quick Installation: Only 3 Triotherm components (upstand, adhesive & screws) secure a straightforward on-site installation with no need for special trades or tools.
