    Window, Door & Double Glazing FAQs

    High-quality double glazed windows can often last 20 years or more when properly installed and maintained. Factors such as frame material, installation quality and exposure to weather conditions all contribute to lifespan and long-term performance.

    Double glazing uses two panes of glass separated by an insulating gap, while triple glazing includes a third pane for additional insulation and noise reduction. Triple glazing can improve thermal performance further, although many homes achieve excellent efficiency with modern double glazed systems.

    Modern double glazing can significantly reduce external noise, particularly in homes located near busy roads or built-up areas. Improved seals and insulated glass units help minimise sound transfer from outside.

    Composite doors are built using reinforced materials designed for strength, durability and security. Many homeowners choose composite doors because they provide a solid feel, improved insulation and enhanced resistance against forced entry compared to older door systems.

    Modern UPVC and aluminium window systems are designed to be low maintenance. Regular cleaning and occasional checks on hinges and seals are usually enough to keep them performing properly for many years.

    Aluminium windows are known for slimmer frames, larger glass areas and a more contemporary appearance. UPVC windows remain popular because they are cost-effective, energy efficient and low maintenance. The right choice usually depends on the style of the property, budget and preferred finish.

    Modern window and door systems are available in a wide range of finishes beyond standard white, including anthracite grey, black, cream, woodgrain and metallic finishes. Many homeowners now choose coloured frames to better suit modern extensions or traditional properties.

    Multi-point locking systems secure the window or door at several points around the frame instead of a single lock position. This improves both security and weather sealing compared to older locking mechanisms.
