Composite Windows
Composite Windows offer an energy-efficient, high-performance and low-maintenance glazing solution.
Aspect Windows’ range of windows includes PVCu/aluminium composites and timber/aluminium composites. A stylish alternative to aluminium, these windows and doors feature external aluminium and internal timber or PVCu making them suitable for both traditional and contemporary style properties.
Composite Windows are manufactured using two materials, such as aluminium and timber together for increased performance and efficiency. They can also be more durable and easier to maintain.
We manufacture, install and supply leading brands such as Internorm, Rationel and VELFAC. These windows are available in a diverse choice of designs and colours, allowing you to choose the windows that match your style and property.

Composite windows are the first choice for homeowners looking to reach PassivHaus standards. They are a great option for homeowners looking to lead a more sustainable property, with many of the timber materials used sourced from FSC-certified forests.
With a wide range of styles and products available, they are perfectly suited to modern new builds to contemporary renovation projects.
