Saxonia Energy
In Germany, Saxonia Energy faced a challenge: how to optimize the insulation of standard district heating pipes operating at 130 °C, a configuration widely used, within limited space, without increasing heat loss.
Originally insulated with compression-resistant lamella mats, the system required a reduction in insulation thickness by 20 mm because of space limitations. To meet performance and durability goals, the insulation concept had to be re-engineered using a smarter, space-saving solution.
A spacer-based solution with high thermal efficiency
The answer came with a complete upgrade to ULTIMATE™ U TECH Wired Mat MT 4.0, applied between spacers. This new configuration not only matched the thermal performance of the original system despite reduced thickness, but also provided improved mechanical resilience and long-term reliability.
Supported by TechCalc calculations comparing various insulation options, the solution delivered:
• A reduction in insulation thickness by 20 mm with equivalent heat loss values;
• Fast and lightweight installation;
• Enhanced mechanical strength for long-term use.
A scalable reference for municipal utilities
With 1,200 m² of ULTIMATE™ material installed, this upgrade now serves as a reference case for municipal utilities seeking durable and efficient district heating insulation systems.
The success of the project was driven by close collaboration with the installer and Saxonia Energy, demonstrating the practical advantages of ULTIMATE™ in demanding technical applications.
This project is now positioned as a best-practice example for future district heating tenders, aligning thermal performance with space efficiency and long-term reliability.
