How It's Built
German engineering you can see
Every profile is an 85 mm, multi-chamber uPVC frame — the cross-section that gives European windows their strength, airtightness and class-leading insulation. Here's the engineering inside:
powerdur inside
Steel-free fiberglass reinforcement bonded into the frame — lighter, rust-proof, and warmer than the steel core that creates a thermal weak point in ordinary windows.
bonding inside
The glass is structurally bonded to the sash, so the whole unit acts as one rigid piece — resisting warping, boosting security, and enabling larger, slimmer sashes.
safetec inside
A third continuous center gasket runs around the frame — an extra barrier against draughts, water and noise, with added break-in resistance.
foam inside
Insulating foam fills the profile chambers for the highest thermal performance — part of how these systems reach Passive House certification.
