Exterior doors and windows
As Europe’s market-leading window manufacturer, the company is at the forefront of innovation and quality—a fact evidenced by over 85 years of tradition and experience, as well as the production of more than 22.5 million windows and doors.
UPVC
PVC is an ideal material for a significant number of windows and doors, as it is dimensionally stable and completely homogeneous, representing a modern and contemporary choice.
The exterior aluminum cladding, available in a wide range of colors, retains its beauty for decades thanks to its durable surface finish. Furthermore, Internorm windows are available in four distinct designs that harmonize perfectly with the building’s style; additionally, the combination of PVC/aluminum and timber/aluminum units creates a unified look across the façade, thanks to their identical exterior appearance.

Timber / Aluminum
Wood is a natural material that radiates warmth; furthermore, it has long been a proven choice in architecture for numerous structural elements serving both functional and aesthetic purposes.
The exterior aluminum cladding ensures the window remains unaffected by the passage of time, while the thermal foam core between the layers further enhances thermal insulation. Additionally, Internorm windows are available in four distinct designs that harmonize perfectly with the building’s style; thanks to their identical exterior appearance, combinations of wood-aluminum and uPVC-aluminum units create a unified look across the façade.
