About our windows
Since 1995, we have manufactured windows at our two factories in Western Jutland. This gives us full control over quality and enables reliable and efficient delivery. All timber used is FSC®- and PEFC™-certified, and our uPVC profiles contain a significant proportion of recycled material. Our materials are selected with responsibility towards both people and the environment.
At Kastrup, quality is not only about materials – it also encompasses consultancy, delivery, and long-term relationships. In short: obvious quality in everything we do.

Tailor-made solutions
Every building is unique. That is why we offer tailor-made solutions, ensuring that your windows complement the architecture while providing optimal conditions for natural light.
We support you throughout the entire process and deliver solutions that combine comfort, functionality, and aesthetics.
Choosing the right windows
When you choose new windows, you also choose comfort, energy efficiency, and peace of mind. Our modern windows are designed for long service life, reduced heat loss, and improved indoor climate.
All our windows feature:
- High thermal insulation, delivering measurable energy savings
- Burglar-resistant solutions as standard, with options for enhanced security levels.
- A refined design suitable for both new construction and renovation projects.
