Windows and doors of obvious quality
At Kastrup, we create frames that give light the best possible conditions. For more than 30 years, we have developed and manufactured windows and doors at our two factories in Western Jutland – always with a strong focus on functionality, aesthetics, and responsibility towards people and the environment.

Windows
As one of Denmark’s largest window manufacturers, we produce windows that frame light and life – built in solid, long-lasting quality and with genuine respect for fine craftsmanship. We offer a wide range of windows in wood/aluminium, wood, and PVC, manufactured with professional pride and attention to detail.
Doors
Doors are a transition. A first impression of what lies beyond. That is why we manufacture doors with precision, material expertise, and a focus on performance, durability, and function. At Kastrup, we supply front doors, sliding doors, and patio doors in wood/aluminium, wood, and PVC – delivering quality that is evident both in appearance and everyday use.

Designed with Kastrup
Our windows and doors are developed to integrate naturally across many building styles - from classic Danish homes to modern, energy‑efficient designs. Each solution is tailored to support the project’s architecture, performance needs, and material palette.
