How It Works
Planning and Engineering
Consulting, planning, and turn-key projects – from initial concept development to turnkey implementation. As an experienced partner, we provide our customers with holistic support through all project phases.
Efficiency through Optimization
In modern glass production, energy efficiency is the decisive competitive advantage. Our engineering services go beyond mere planning: We analyze existing plant concepts and develop strategies for significantly reducing the CO2 footprint. Through precise calculations for heat recovery and the use of modern insulation techniques, we optimize the thermal efficiency of your glass melting furnaces.
Our range of services includes:
Energy & glass quality check: Calculations for optimizing consumption with the highest glass quality.
Design and execution planning: Consideration of technical, economic and energy-related requirements.
Project management: Coordination of all participating trades for smooth implementation.

Technical Planning with CAD
For precise project implementation, we rely on state-of-the-art CAD technologies. We create all necessary technical documents:
Layout and foundation plans
Static calculations
Static calculations, schematic and flowcharts
Installation and assembly plans
2D & 3D modeling
This methodical combination of technical precision and forward-looking calculation forms the foundation for risk-free implementation.

"We transform complex technical challenges into ready-to-use competitive advantages."
How It Works
Worldwide Service for Glass Melting Furnaces
IWG offers worldwide service and reliably supports customers throughout the entire lifecycle of glass melting furnaces. Our international service team is available for new construction projects, modernizations, and optimizations.
Our global service offerings include:
Construction management & assembly
Glass draining
Employee training
Commissioning & tempering
Technical advice

Downtime Management
Unplanned downtimes are the biggest risk in the glass industry. Our specialists perform hot repairs during ongoing operations (e.g., replacing burner blocks or repairing the crown) to extend the service life of your furnace without a complete drain.
Strengths
Quality Assurance and International Standards
The high quality standard of our services is continuously developed through close collaboration with renowned external consultants from universities, research institutes, and the industry. Every project undergoes a strict quality assurance process with us, which considers all technical, economic, and energy-related aspects.
Our customers benefit from transparent project communication, on-time delivery, and technical documentation that meets the highest global standards. This gives you the assurance that your investments are protected for the long term and your plants are always operating at their optimum.
