Aluminium Casement Doors
A casement door is the ideal addition to any glazing package and serves as the perfect door system to complete a rear extension or any project of the sort.
Our aluminium doors are made from robust thermally broken aluminium profiles from our fabrication factory. With a range of profiles available we are able to offer an aluminium door to suit almost any project specification.
The standard aluminium profiles are able to create hinged aluminium doors up to 3m in height and a maximum of 1.4m wide per door opening.
With high levels of security and weather resistance in slim aluminium frames, you can create elegant side doors, rear doors or balcony doors.

Modern Casement Doors
Aluminium casement doors can be designed with an inward or outward opening as required with a low threshold door base, which is both wheelchair and pushchair friendly.
An aluminium French door configuration is the perfect option for larger openings or for modern Juliet balconies to upper floors.
The aluminium profiles can be powder coated a RAL colour to suit all project specifications. We also have a range of lever/lever handles available to choose from to ensure that your aluminium door meets your exacting requirements.

Casement Door Options
IQ offer a wide range of casement doors ranging from our classic Sieger casement door to our Sieger Lux casement range.
It is important that expansive options are presented to ensure that you can select the correct bespoke door for your project. If you desire slim frames and minimal sight lines, then our Sieger Legacy range would be ideal for your next project.
Various configurations can also be specified for more unique openings. Our different casement ranges feature their own unique configurations to guarantee that nearly all openings can be filled.
Aluminium Casement Doors for Indoor-Outdoor Living
Aluminium casement doors provide a practical and elegant connection between interior spaces and the outdoors. Ideal for garden access, patios, balconies and contemporary extensions, these hinged doors allow natural light to flow through a space while creating convenient access to the outside.
Available as single or double-opening French doors, Sieger® aluminium casement doors can be configured to suit the layout and proportions of each project.
Inward or outward opening options, alongside low-threshold configurations where specified, provide flexibility for a range of residential and commercial applications.
Bespoke Aluminium Casement Door Designs
From contemporary homes to properties requiring a more traditional aesthetic, aluminium casement doors can be tailored to complement the surrounding architecture. The Sieger® range offers a choice of door configurations, frame profiles and polyester powder-coated finishes, including RAL colours, to coordinate with the wider glazing scheme.
For projects seeking a more distinctive appearance, the Sieger® Legacy range offers a steel-look aesthetic, combining characterful glazing bars with the benefits of modern aluminium construction.
Whether specifying a simple single door or a double-door arrangement with complementary fixed glazing, each design can be considered in relation to the project's architectural style and functional requirements.
Thermal Performance
Designed to balance architectural appeal with practical performance, Sieger® aluminium casement doors incorporate thermally broken aluminium profiles to help reduce heat transfer through the frame. Combined with suitable insulated glazing, the system can support the thermal efficiency and comfort of the building.
Security and weather resistance are equally important when specifying external doors. Tested system performance, multi-point locking mechanisms and robust hinge hardware help support secure, reliable everyday operation.
Available performance varies according to the selected door system and specification, allowing the appropriate configuration to be identified for the requirements of each project.
