For more than 50 years, Glas Natter and LiSEC have built a partnership defined by technical progress and fully integrated machinery solutions. Based in Regensburg and operating for over 170 years, Glas Natter has transitioned from a traditional glass supplier to a modern processor specializing in high-efficiency insulating glass, laminated safety glass (LSG), coated assemblies, and warm-edge façade units. Around 80% of the company’s insulating-glass production incorporates LSG, particularly in triple glazing and noise-reducing façade systems where impact resistance and acoustic control are crucial.
Glas Natter’s factory layout is almost entirely built around LiSEC technology, creating a continuous in-house workflow. The current setup includes:
- AUT-D & ESL-A automated storage and loading systems
- LiSEC GFB cutting table with breakout optimization
- KSR & KZW edge grinding and arrissing modules
- TPS and warm-edge spacer insertion systems
- Automatic gas filling with argon and krypton control
- SRP-A sealing line with precision bead application
- LiSEC software for production sequencing, defect tracking, and batch auditing
This unified line eliminates manual transfers and reduces handling stress, ensuring consistent edge quality, improved gas retention rates, and fewer rejects under EN 1279 performance standards.
Glas Natter was one of the first European processors to commission the LiSEC SRP-A sealing platform, designed specifically for thicker and more complex unit geometries. The system supports: 
- IG thickness up to 80 mm
- Oversized façade panels and irregular layouts
- Hot melt, polysulfide, and silicone secondary sealing
- Warm-edge spacer systems including TPS, Swisspacer, and flexible structural spacers
The Full-Support Belt System stabilises units even when corner sealant overhangs, preventing torsion and ensuring precise secondary sealing depth. Combined with the new suction-axis holding mechanism, the SRP-A maintains alignment even on triple units with Low-E coatings and laminated layers, where differential weight distribution is typically a challenge.
Glas Natter plans further integration of LiSEC’s analytics platform, enabling predictive maintenance, sealant consumption monitoring, and real-time production tracking. These upgrades support tighter tolerances in U-value performance, edge conductivity, and seal durability, which are increasingly demanded in contemporary glass façades.
