Windows

The Sieger Slim Casement Window is an award-winning glazing system; it was the winner of the Best Glazed Window in the Build It Awards.

It offers exceptionally modern design qualities due to the beautifully slim profiles that are available in a whole array of configurations, and colours to suit the project requirements.

Our modern aluminium windows are a fantastic choice for both new buildings and as replacement windows on existing buildings.

They provide a simple yet effective window design that boasts high levels of thermal performance and PAS 24 certified security.

Even with the slim sightlines our aluminium windows can still achieve impressive opening sizes, while fixed windows can be manufactured to even greater sizes.

The Sieger slim casement system is perfect for gable end glazing, shaped openings, and areas of glazing surrounding door systems.

To ensure the Sieger Slim Casement Window provides the highest levels of insulation, the latest thermal break technology is integrated within the profiles of the system.

This system has been fully tested for weather, thermal insulation and has been through stringent security testing.

To view a fullsize installation of this system, you can visit the Sieger Systems showroom within Sky House Design Centre located in Amersham, Buckinghamshire.
