    Aluminium vs uPVC Windows: Which Should You Choose?

    Frame appearance, thermal performance and value: choosing the right material for your home.

    Why choose uPVC windows?

    Modern uPVC windows offer good thermal performance, low maintenance and excellent value.

    They remain one of the most popular options for replacing windows throughout an entire property.

    Why choose aluminium windows?

    The strength of aluminium allows comparatively slim frame profiles while supporting substantial areas of glazing.

    This makes aluminium particularly attractive for contemporary homes and extensions.

    Choosing new windows is one of the larger improvements homeowners make to their property, and one of the first decisions is often whether to choose aluminium or uPVC.

    There isn’t one correct answer for every property.

    Why choose uPVC windows?

    Modern uPVC windows offer good thermal performance, low maintenance and excellent value.

    They remain one of the most popular options for replacing windows throughout an entire property.

    A wide range of styles is available, including conventional casement and flush casement designs.

    Why choose aluminium windows?

    The strength of aluminium allows comparatively slim frame profiles while supporting substantial areas of glazing.

    This makes aluminium particularly attractive for contemporary homes and extensions.

    Aluminium windows can also work particularly well alongside aluminium bifold or sliding doors, creating a consistent appearance across the property.

    Which is more suitable for your home?

    The decision should take into account:

    • Property style
    • Desired appearance
    • Budget
    • Window sizes
    • Thermal requirements
    • Other doors and glazing being installed
