    A Homeowner’s Guide to Replacing Windows

    A practical checklist covering style, materials, ventilation, glazing and final measurements.

    Replacing windows can improve the appearance, comfort and performance of a property, but there are several decisions to make before ordering.

    Aluminium or uPVC?

    uPVC provides excellent value, low maintenance and good thermal performance.

    Aluminium provides slim profiles, strength and a contemporary appearance.

    The right material depends on the property, required appearance and budget.

    Choose the right window style

    The proportions and opening configuration can have a surprisingly large effect on the appearance of a house.

    Consider how the new windows relate to the architecture rather than simply replacing every existing window with an identical configuration.

    Flush casement windows can also provide an alternative to conventional casement designs.

    Think about the entire property

    If windows, entrance doors and rear doors are being replaced, consider them as one overall design.

    Coordinating frame colours and styles can produce a much more consistent result.

    Consider ventilation

    Ventilation requirements should be considered when specifying replacement windows.

    Depending on the installation and applicable Building Regulations, background ventilation such as trickle vents may be required.

    Consider the glazing

    Glass specification affects thermal performance, safety and comfort.

    Different areas of a property can also have different requirements.

    Accurate surveying matters

    Replacement windows are manufactured to fit individual openings.

    Accurate final measurements are therefore an important part of the process before manufacture begins.
