Triotherm - the Innovative Solution for Windows & Doors

Triotherm, a patented solution developed by Meesenburg GmbH & Co. KG, located in Flensburg, Germany, was initially engineered to enhance the installation of windows and doors within the insulation layer. Although this innovative method has demonstrated its efficacy across continental Europe, its application in Ireland and the United Kingdom predominantly focuses on serving as an insulated threshold beneath doors and floor-to-ceiling windows.

 

What is Triotherm? Triotherm is crafted from high-quality expanded polystyrene (EPS) with a density of 150 kilograms per cubic meter. This advanced material facilitates optimal load distribution while ensuring the thermally efficient performance of the door upstand.

 

 

Advantages of Triotherm as a Door Upstand:

  • Optimal Thermal Performance: Triotherm exhibits thermal performance equivalent to standard mineral wool insulation. This methodology effectively mitigates thermal bridging and ensures superior heat retention at the floor level.
  • Structural Support: Triotherm efficiently transfers the load of the door directly into the building's structural framework.
  • User-Friendly Design: Triotherm streamlines the connection details between windows, doors, and the floor, facilitating a more coherent installation process.
  • Efficient Installation: The installation process is simplified using only three Triotherm components (upstand, adhesive, and screws), allowing for a straightforward on-site installation that does not require specialized trades or tools.

 

 

Why to use a Triotherm door upstand?

 

  • Improved Energy Efficiency: Triotherm provides insulation that is approximately nine times more effective than traditional thermal blocks and thirty-three times more efficient than concrete.
  • Elimination of Thermal Bridges: Triotherm's door upstands are specifically designed to prevent cold bridges, thus mitigating areas where heat can escape from the building.
  • Moisture Resistance: In contrast to timber, concrete, stone, or brick, Triotherm exhibits a water absorption rate of ≤ 0.5 vol.% after 28 days of submersion, as verified by tests conducted in accordance with DIN 12087 standards.
  • Enhancement of Overall Building Performance: The incorporation of an insulated door upstand substantially contributes to a more energy-efficient building envelope. This is achieved through continuous insulation layers and the reduction of thermal bridges.

 

 

Installation Insights for a Sliding Door Upstand

We’re excited to share more details about the installation process of a Triotherm insulated door upstand for a sliding door, recently used in our own retrofit project. Since most sliding doors come with a frame depth exceeding 125mm, you may need to extend the standard Triotherm+ profile by incorporating a structural insulation board upright or even by using two rows of Triotherm+ for optimal results.

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 be positioned to maintain continuity with the building’s insulation layer for optimal performance. Below, you'll find guidance tailored to the most common wall systems.

Triotherm from an Environmental Perspective

Building materials inevitably have an environmental impact. The important question is therefore not whether a product is completely impact-free, but how well it balances durability, thermal performance, structural performance, resource efficiency and end-of-life options.
