The Kruger Tilt and Turn Window

Sunlight floods through expansive glazing, illuminating the space without unwanted heat loss. Air moves freely, fresh and controlled. No draughts, no wasted warmth, just a perfectly balanced indoor environment where insulation and ventilation work together in quiet harmony.

Every material around you is natural, breathable, and built to last—designed not just for efficiency, but for wellbeing.

A truly low-energy building starts with the right materials: airtight, thermally efficient, and made from natural materials. The Kruger Tilt and Turn Window is designed for fabric-first construction, passive design, and net-zero projects, delivering exceptional airtightness, outstanding energy efficiency, and complete flexibility of use.

Its inward-opening design allows for secure night-time ventilation, while its large sash sizes maximise natural light and uninterrupted views. Outside, it maintains clean lines and a modern aesthetic. Inside, it transforms the way you experience your space.

For those who demand performance without compromise, the Kruger Tilt and Turn Window is the future.
