Triotherm - the most innovative structural insulation system for your windows and doors offers the following benefits:
Enhanced Thermal Insulation
Triotherm structural insulation eliminates thermal bridges between window or door frames and the surrounding building structure, significantly improving the building's overall thermal insulation. This translates to reduced energy consumption and lower heating costs, making Triotherm a cost-effective solution in the long run for energy efficient buildings.
Simple and Quick Installation
All Triotherm components are designed for ease of use, with its interlocking profiles and lightweight construction making it simple to install even for self-builders. The system is compatible with any door or window system, allowing for its use in a wide range of building applications.
Suitability for Various Applications
Triotherm is a versatile structural insulation system, suitable for supporting windows without traditional window sill support as well as insulated upstand for doors in all types of buildings. Its exceptional thermal insulation combined with structural support properties make it particularly ideal for energy-efficient homes like passive houses and nearly zero energy buildings.
Extensively Tested & Approved
Triotherm+ is supported by extensive independent technical and environmental documentation, including ETA-23/0620, an independently verified Environmental Product Declaration (EPD), Passive House Institute certification and EMICODE EC1 Plus.
