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.

 

Positioning of Triotherm Door Upstands

Proper positioning of Triotherm Door Upstands is crucial to ensure optimal thermal performance while minimizing disruptions to subsequent trades. Ideally, the upstand should align closely with the top of the door or window frame. The exact placement within the door or window opening will depend on the specific wall construction. In general, the door upstand should align seamlessly with the building's thermal envelope for optimal performance. Below, you'll find guidance tailored to the most common wall systems.

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.
