Our uncompromising attention to perfection extends to every stage of the window and door ecosystem, which is why we are so confident.
Pioneered in energy-conscious Europe and then introduced to America 40 years ago, KULU window and door systems set world-class efficiency, design, comfort, operational ease, and home innovation standards.
High-performance windows and doors by KULU benefit your entire building design. Our commercial fenestration solutions give you the freedom to create building envelopes with substantial windows that minimize energy loss.
GENEO® is composed of RAU-FIPRO®, a proprietary fibre composite parallel to those employed in aeronautic construction and racing vehicles for exceptional strength and load capacities.
This incredible design has perfected style and function. As a result, the tilt-turn is the dominant window style in Europe, now gaining popularity among discriminating architects, designers and homeowners in North America.
