Custom Windows Made in Europe

European windows are often manufactured to order, not mass-produced. That means better alignment with your project’s dimensions, style, and energy requirements — with factory-level precision and quality assurance.
  • We help you customize windows down to every detail: dimensions, color, opening type, glazing, hardware & accessories.

Why European Windows Are More Affordable Than You Think

Thanks to modern manufacturing, strong competition, and scalable production, European windows often deliver better specs for a lower cost than their US counterparts — especially for high-performance profiles.
  • Lower U-values, stronger frames, better pricing. It’s not just marketing — it’s engineering efficiency.

European vs. American Installation Differences

European windows are typically installed using a tighter, more insulated method — often flush with the wall and sealed with vapor barriers and tapes. This method supports higher energy performance and longer-term protection.

  • Precision installation = better insulation, reduced air leakage, longer lifespan.

What Do European Windows Look Like?

They feature slim profiles, modern lines, and hidden hardware — often with tilt-and-turn functionality and more glazing surface compared to US windows. Perfect for modern, minimalist, or Passive House designs.

  • Form follows function — and both are elevated.

Should Spec Home Developers Consider European Windows?

Yes — especially if you’re aiming to differentiate your builds, increase energy performance, and reduce callbacks. EU windows bring both performance and aesthetics that buyers notice.
