    A variety of uPVC windows and aluminium windows fit for any Kent property

    At Fineline Windows, we offer high-quality, durable uPVC windows that require minimal upkeep. They resist rot, corrosion and fading, ensuring long-lasting optimal condition. UPVC windows are energy-efficient, providing excellent insulation year-round for reduced heat loss in winter and heat gain prevention in summer.

    Our aluminium windows combine strength with aesthetic appeal, featuring slimline frames and large glass areas for unobstructed views and abundant natural light. They are highly resistant to weathering, corrosion and fading, requiring minimal maintenance.

    Customisable to fit various architectural styles, from the colour to the accessories, aluminium windows offer excellent thermal efficiency, noise reduction and enhanced security with multiple locking systems.

    A wide range of window styles for homeowners in Kent

    We understand that every home is unique. That's why we offer a diverse selection of new windows to suit various styles and personal tastes. Our varied range includes:

    Casement Windows

    Casement windows are a popular choice for homeowners seeking a combination of classic aesthetics and functionality. These windows feature hinges on one side, allowing them to open outward like a door. The beauty of casement windows is their simplicity and versatility, making them suitable for various properties, from traditional to contemporary.

    Sash Windows

    For those seeking to preserve the timeless charm of period properties or add a touch of elegance to their home, sash windows are an excellent choice. Vertical sliding windows consist of two panels, known as sashes, that move up and down within the frame. We offer sash windows that combine traditional aesthetics with modern features.

    Bay Windows

    Bay windows are an architectural feature that can transform the look and feel of your home while providing additional space, abundant natural light and panoramic views. Comprising three or more windows projecting outward from the main structure, bay windows create a beautiful focal point and add a sense of grandeur to any property.

    Tilt-and-Turn Windows

    Tilt-and-turn windows offer a modern and practical solution for homeowners seeking maximum flexibility, ease of maintenance and enhanced security. These windows feature a dual-opening mechanism that allows them to be tilted inwards from the top for ventilation or swung open sideways like a casement window for easy cleaning and emergency egress.

    Should I replace 20 year old double glazing?

    It is worth considering replacing your old double glazing. Outdated windows may lead to increased energy costs and decreased winter comfort. Upgrading to new, high-performance windows can make your home warmer and more energy-efficient.

    What style of windows suit Kent homes best?

    For Kent homes, traditional sash or casement windows often suit best, preserving the region's classic charm. Modern uPVC or timber frames provide durability and energy efficiency, fitting both period and contemporary properties while enhancing the aesthetic appeal and comfort of the home.
