Bi Folding Doors

The indoor-outdoor living life-style is becoming increasingly popular in the UK, bi-folding doors are growing to be the most popular home improvement product available. By using only the highest quality aluminium, paired with expert engineering, these imposing bi-folding doors can be created in expansive sizes with slim frames to create full floor to ceiling elevations of minimally framed glass. By creating walls of aluminium framed bi-folding glass, properties can be opened up to the outside with one easy swipe to the side. Sieger’s modern thermal break technology provides advanced thermal performance systems to deliver comfort and energy efficiency to households.

Sieger can offer a wide range of ironmongery and handle options to suit each bi-folding system, offering flexibility to each design. The aluminium framing of the systems can be powder coated in any RAL colour desired – our powder coating is UV stable and available in a marine grade for coastal homes.

Casement Doors

Not every project requires a vast wall of glass; some areas largely benefit from a simple yet effective casement door providing access to outdoor living areas. Sieger has modern single opening aluminium doors to suit all types of home design and opening size. The modern aluminium framing used by the Sieger systems, means that these casement doors can be manufactured at large sizes.

Various glass options are available with Sieger aluminium systems, including privacy glass, decorative glass and solar control coated glass. For a traditional steel look door, we can mimic a steel Art Deco style door with horizontal and vertical glazing bars – but with the thermal performance levels of modern glazing systems.

Sliding Doors

Sieger have a range of sliding door options to suit all building designs, opening sizes and performance requirements. These sliding doors come with an aluminium frame with a sightline as little as 20mm boasting an impressive ratio of glass to frame.

By creating large sliding walls of glass, the transition from inside to outside is almost seamless, which is accentuated by the minimal frame width available with this aluminium Sieger system.

All Sieger aluminium sliding doors are fully tested for water tightness, air tightness and the ability to stand up against high force winds. A fully integrated drainage system is available as an additional extra, to ensure that the large sliding doors provide a fully watertight seal to your home.

Windows

Sieger Aluminium Systems offer a wide range of window systems to suit a broad variety of architectural designs. From slim casement windows, steel replacement windows, gable end windows, flush windows and thin framed facades Sieger create and install bespoke windows for projects of all sizes.

Sieger’s steel replacement windows offer the traditional design of the industrial style steel framed windows but with modern performance levels. These steel-look aluminium windows can be used to replace existing steel windows, or on traditional homes or to create an industrial design to new buildings.

Gable End Windows create a beautifully finished gable end to properties, the slim framed aluminium windows allow natural light to flood the property and fill the internal living spaces with natural light. The Sieger gable end windows are manufactured bespoke to each property, to provide a unique design to modern properties.

The slim casement windows for Sieger can be designed in a variety of configurations to suit the requirements of the project. These windows are a fantastic choice for both new and replacement windows as they provide a simple yet effective window that boasts high levels of thermal performance. The aluminium frames can be finished in a Polyester Powder Coat (PPC) in any RAL colour desired for the project.

For a contemporary aesthetic, Sieger manufacture and install thin framed facades that are the next generation in of slim curtain walling systems, creating large glass walls with sightlines almost as slim as frameless structural glass.
