Blaugelb Triotherm+ Precasings – RAL Certified Thermal Installation System, 3 Insulation Zones
The only precasing with 3 distinct insulation zones — completely eliminates installation thermal bridge. RAL Montajeleitfaden certified, mandatory for nZEB and A+ buildings.

Key advantages
- 3 XPS insulation zones — the only system that eliminates thermal bridge in all 3 planes: inner, middle and outer, eliminating condensation and mould at the joint
- RAL Montajeleitfaden certification — the German installation standard recognised in energy audit and building certification, mandatory for A and A+
- Installation heat loss reduction ≥ 90% — without Triotherm+, installation thermal bridge can cancel 20–30% of the window's performance
- Compatible PVC, aluminium, wood — a single system for all building joinery, regardless of material or wall thickness
- Fast clip-on installation — fixed to wall before the window, perfect alignment guaranteed, no structural modifications
- λ = 0.040 W/m²K — thermal conductivity 4 times better than concrete, insulates the joint at wall level
Blaugelb Triotherm+ precasings are the most advanced thermal mounting system for windows available in Romania, the only one that integrates 3 distinct XPS insulation zones (inner, middle, outer) for the complete elimination of the linear installation thermal bridge. Without Triotherm+, even the most high-performance Passive House window installed classically generates a thermal bridge at the joint that can cancel 20–30% of the window's thermal efficiency — this is the main cause of condensation and mould at the window frame in modern, well-insulated homes. The system is certified according to RAL Montajeleitfaden — the German quality standard for window installation, recognised in any European energy audit and mandatory for A and A+ building energy certification. Thermal conductivity λ = 0.040 W/m²K (equal to mineral wool) insulates the joint at the thermal level of the wall, eliminating the "cold ring" around the window frame that promotes mould. Neofort BIZ includes Blaugelb Triotherm+ installation in RAL-certified premium packages and recommends it for any new nZEB construction or energy renovation project.
