How much do aluminium windows cost?

First choice for modern architectural design

Aluminium windows are often the first choice for modern architectural design projects due to their integral strength and their ability to be manufactured with exceptionally slim frames for a super contemporary aesthetic. The aluminium window profiles come in a variety of designs to suit a range of architectural designs.

Whether it’s large window openings or elegant slim frames, the aluminium window range from Sieger® Systems has an option for any project. The strength of aluminium creates window frames that can withstand all weather conditions with no expansion or contraction during frosts or when they are exposed to direct sunlight for lengthy periods of time.

All Sieger® Systems are designed to achieve the appearance and performance of a premium system at a more accessible price point without compromising on quality. The award-winning Sieger® Casement Window is the most cost-effective window solution available from Sieger®. This system won in the ‘Best Windows’ category of the Build It Awards 2018.

What do I need to consider when specifying aluminium windows?


When specifying aluminium windows, it is important to know about thermal break technology, especially when specifying metal framed window systems. Thermal breaks are a very important aspect of the make up of an aluminium window, the polyamide thermal break dissects the internal and external frames to avoid cold bridging and therefore stops condensation build up and thus results in a thermally insulated solution.


Which window configuration and frame finish should I have?


With the Sieger® Systems there are many configurations available. The configurations best suited for each window on a project depends greatly on various aspects of each architectural design including the size of the window, the intended design, the ventilation requirements and the floor level that the window is situated on.

The Sieger® Systems are available with several standard RAL colour finishes that the Sieger® fabrication factory keep in stock, however, there are also various specialist finishes available that can be applied to the aluminium frames at an additional cost. Therefore, the price of the glazing system can vary depending on the frame finish desired for the project.

Sieger® have a choice of styles to create either a minimalistic, contemporary aesthetic or a sophisticated Bauhaus inspired steel-look design. The Sieger® Legacy range of glazing systems are a great example of a cost-effective solution for a style that is traditionally manufactured from steel and therefore an expensive option. Both of these designs are available to view in the Sieger® showroom, simply call the team to view them in person.


What is the typical cost of an aluminium window from Sieger®?


Typically, Sieger® Aluminium windows on average cost approximately £550 per m2, however, this is greatly determined by the desired size of the system, whether any specialist frame finishes are desired and the glazing specification etc.

For a more accurate cost the team would need to know the rough sizes of the openings for the window, whether any specialist glazing finishes are going to be specified (e.g solar control glass) and the location of the project (if we are going to complete the installation as well as the design and manufacture of the system).
