Triotherm - the Innovative Solution for Windows & Doors

Triotherm, a patented product by Meesenburg GmbH & Co. KG (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.

 

Why you should consider using a
Triotherm insulated door upstand?

  • Improved Energy Efficiency: The energy efficiency of Triotherm is comparable to mineral wool, 9 times higher than thermal block, and 33 times higher than concrete.
  • Eliminates thermal bridges: Triotherm door upstands prevent cold bridges, which are areas where heat can easily escape your building.
  • Moisture-resistant: Unlike timber, concrete, stone, or brick, Triotherm water
    absorption rate is just ≤ 0.5 vol.% after 28 days of submersion,
    as tested according to DIN 12087 standards.
  • Enhances overall building performance: An insulated door upstand contributes to a more energy-efficient building envelope. The basic principles for this are a continuous insulation layer and the minimising of thermal bridges.

 

Understanding Door Upstands

A door upstand is a vertical section which is is placed at the bottom of a door opening. Its primary function is to provide a structural support for the door without creating heat loss.
