Triotherm thermal structural supports for windows & doors !
Say Goodbye to inadequate support strategies
We´ve all seen that certain type of creativity when it comes to potential solutions for structural door & window support, mainly created with plenty of effort but still poor.
Timber is not the greatest idea for supporting doors & windows in external wall insulation layers. Beside the fact that the load bearing isn´t certified, there´s always a high risk of rot.
Steel brackets can definitely carry the weight of doors and windows but have to be manufactured bespoke. Also, they can create a serious thermal bridging.
The common strategy of filling the space underneath the threshold with concrete, once the door is installed, will lead to problems with thermal bridging and moisture transfer.
Installing windows and doors has to become more challenging over the last decade due to permanently increasing insulation requirements and heavier windows and doors, mainly caused by triple glazing.
The growing demand for large-sized sliding doors and floor-to-ceiling windows in new builds, as well as new insulation methods like external wall insulation, is putting pressure to architects, builders and window suppliers regarding practical solutions for supporting windows and doors.
The most previous attempts for supporting windows and doors were not practical for the following reasons:
- Wrong material (e.g. timber with a high risk of rot)
- Risk of heat loss (e.g. supports made of concrete or steel)
- Complicated installation (e.g. bespoke brackets and fixings)
Why should you opt for Triotherm thermal structural supports ?

The thermal image overlay was taken in March 2022 at the bottom of a french door in an existing building, which got recently a deep home energy upgrade through a leading One-Stop-Shop for nZEB retrofit.
Unfortunately no further attention has been taken to reduce the thermal bridging at the door threshold level during the retrofit process.
As a result you can clearly see the significant heat loss through the floor area, with temperatures at the door threshold, equivalent to ambient temperature. The floor area further inside of the room is significantly warmer, thanks to the new installed underfloor heating.
The window installation in the insulation level (EWI) for a new build was realised at the beginning of 2022 by using steel brackets. This results in an increased installation effort as well as a potential deterioration of the overall thermal insulation value of the window (as you can see in the Passive House Institute study further down below).
Since the load is only transferred at certain points, the correct dimensioning of the fasteners is also extremely important and potentially challenging.
The outer sealing level, to prevent water ingress, is very difficult to create, because the steel brackets hinder a clean and continuous seal. Likewise, the insulation material must be recessed around the brackets, which can easily lead to thermal bridging.
Load Transfer
The weight of the door or window must be transferred into the building structure securely , to ensure the functional performances like open/close, rain shelter and wind protection.
Insulation Performance
Low u-values of doors & windows will be degraded by thermal bridging, caused by the use of highly heat-conductive materials (e.g. steel & concrete) or wrong location .
Secure Installation
The best theoretical installation detail is useless when it can´t brought forward into reality. Efficiency and simplicity are the main challenges for a successful installation on site.
How to achieve the secure support of your windows and doors without thermal breaks ?
By using the TRIOTHERM System - the most advanced thermal structural support system for doors & windows
Which key details make the Triotherm thermal structural supports so unique ?
Load Transfer
Triotherm guarantees a load transfer of at least 200kg per 10cm, even in the pre-wall installation version. The secure fastening is part of the Triotherm System and thus simplifies construction processes.
Insulation Performance
The currently confirmed thermal conductivity for the Triotherm+ profile is 0.040W/m²K (only), which means that the thermal insulation properties of the selected windows and doors are hardly deteriorated.
Simple Installation
Triotherm+ thermal brackets come in a length of 1,175mm and a maximum weight of 4kg per profile. It can be easily transported to the construction site and assembled on-site to the desired length using the integrated dovetail joints.
Using the Triotherm thermal structural support system for doors and windows is creating noticeable relief for architects, builders and window suppliers. However, the homeowner benefits most from the advantages of Triotherm thermal brackets because she can enjoy her windows and doors without any restrictions in terms of use and comfort.
All Triotherm components have been extensively tested for various parameters, to ensure that they´ll meet and exceed all required specifications and building standards.
