Kastrup Windows perfectly combine the Danish eye for style and design with high-performance plus exceptional engineering quality.

Kastrup windows have high levels of thermal efficiency, with Uw values as low as 0.76 (suitable for passivhaus projects). They also have superb acoustic performance, keeping your home peacefully quiet. Kastrup windows have alumnium cladding on the outside for long-term low-maintenance sustainability. On the inside is Scaninavian timber which can be stained or factory painted in various colours.

All our Kastrup windows & doors are 100% custom-built to order by craftsmen in West Jutland, Denmark.

The heartwood of North Scandinavian pine is cut to avoid knots and warping of the timber.

• The outside of the timber is almost maintenance-free due to the resistant aluminium frame.

• The frame profiles are made of a fibreglass-strengthened composite which ensures high thermal insulation and structural stability.
