Triotherm+: Window and Door Installation for High-Performance Buildings

Offering unparalleled thermal insulation, structural stability and design versatility, the blaugelb Triotherm+ system is the industry-leading thermal window buck system for energy-efficient building. Certified for Passive House construction.

The blaugelb Triotherm+ system sets a new benchmark in high-performance window and door installation allowing for the window unit to be integrated directly into the main insulation layer. This eliminates thermal bridging, simplifies installation, and extends the project life.
In short, a simple and versatile, yet highly effective solution for better window and door installations.
