Minimalistic designs, hybrid materials and rising sustainability demands are redefining
modern window systems. We spoke with Harald Krämer, Senior Market Manager Industrial Segment Windows, Doors and Profiles at Lohmann, about what really matters and why simplicity without compromise is becoming a decisive success factor.
Harald, what is currently driving window design?
Minimalism. Slimmer profiles and larger glass surfaces are clearly dominating architecture. But these designs only work if performance keeps up. Reduced tolerances and higher loads demand bonding solutions that are absolutely reliable over the long term.
How are materials influencing system complexity?
Material diversity is now standard. Aluminium, PVC, wood, composites, often combined in one system. The challenge is ensuring consistent performance across all of them. That’s exactly where our claim comes from:
All Frames. One Tape. Zero Compromise.
With Lohmann SDG® technology, the Static Direct Glazing, partners can rely on one bonding solution across different frame materials without redesigning their systems.
Sustainability is everywhere. What really makes a difference in windows?
For me, sustainability is mainly about service life. A window that lasts longer has a much smaller environmental footprint. With SDG technology, we’ve achieved a minimum 30-year service life, officially recognized by the German Federal Office for Building and Regional Planning (BBSR). That turns sustainability into a measurable, verifiable performance factor.
What does this mean for manufacturers and distributors?
It reduces complexity and creates trust. One technology for proven durability. That’s a strong argument, especially in sustainability-driven tenders and long-term investment decisions.
What can visitors expect from Lohmann at Fensterbau Frontale?
We’ll show how SDG technology enables future-ready window systems across all frame concepts for combining design freedom, certified durability and sustainability. And, of course, meeting us for personal conversations to exchange ideas and opportunities.
All Frames. One Tape. Zero Compromise.
A clear value proposition for decision-makers focused on efficiency, sustainability and long-term competitiveness.
Ready for the Next Step
At Fensterbau Frontale, Lohmann demonstrates how SDG® technology streamlines window production, from the shop floor to the balance sheet.
Looking forward meeting you at our booth 6-455 in hall 6!
