    Advice and Guidance

    Explore a range of window designs to suit any home

    Replacing windows is a sure way to improve your home and increase its value. Since they are such a prominent part of the exterior, it’s important to fit the perfect style to suits your home and area. We offer so many designs and styles, materials and options, you’re sure to be able to find the combination that works best for you.

    All our windows are made to measure to a range of designs, but even if your needs are a little bit special, such as arched, octagonal or round windows, we can help with bespoke designs to fit.

    There’s also a large collection of window furniture designs to choose from, including monkey tail handles, contemporary metal handles and genuine sash window lifts and fasteners in a range of chrome, brass and metallic colour choices.

    Energy-efficient window installations across Tonbridge, Rochester and Canterbury

    Our highest-rated double glazed windows have an energy A+ rating (the highest there is). So, you can be sure that they’ll keep the inside of your home at an optimum temperature.

    Efficiency is a result of careful design and engineering. Our windows feature new performance oriented technologies including multi-chambered window profiles, argon-filled inter-pane areas, low-e glass that’s specially treated to reflect heat back into a room, and the newly patented Warm Edge Spacer Bar.

    In a commitment to sustainability we include almost 100% biodegradable EcoMAX Glass™ as a standard fitment on all uPVC and aluminium products. We also offer Comfort Glass that is designed to outperform triple glazing thanks to the inclusion of a tough laminated layer and an effective low-e coating.

    For dreamy days and quiet nights

    On top of a window’s thermal performance its sound insulation is the next most important consideration. Noise cancellation is to a degree a bi-product of good heat retention.

    Warm Edge Spacer Bars, multi-chambered profiles and argon-filled inter-panes all dampen noise in double glazing and Comfort Glass windows, but expert workmanship also helps. Snug seals, panes and frames are tightly fitted for a draught-free, quieter design.

    Sleep safe and sound with highly secure windows

    Even if you live in a low-crime area, it’s good to review the security of your windows, particularly as upgrading your windows could also reduce your insurance premiums.

    Our range of window security features  includes multi-point locking systems, multi-layered beaded frames that resist harsh forces, high-quality handle locks and shoot bolt locks. Our aluminium windows are tested to PAS 24.

    We can also fix uPVC window hardware into steel reinforcements and incorporate toughened glazing. A range of additional locking mechanisms can also be incorporated into our window styles if security is your greatest concern.

    Double glazing or Comfort Glass for new windows?

    EcoMax double glazing (our standard fitment) and Comfort Glass enhance energy efficiency and reduce noise pollution. But which is best for your home’s replacement windows?

    Double glazing is made from two high-performance panes of glass with a layer of argon gas between that is sealed with a warm edge spacer bar. Comfort glass combines two highly efficient glazing panels with a built-in laminate layer and a special transparent Low-E coating that stops 56% more internal heat from escaping. A much more effective insulator than triple glazing.

    All of our windows are A-rated for their thermal efficiency, so either is a good choice, but if you feel you need the additional performance, Comfort Glass might be the best choice—especially in large glazed areas such as sliding or bi-fold doors.

    Windows with integrated blinds

    Integral blinds are effective at blocking heat and light, offer greater privacy and provide protection for your furnishings and interior from too much sun.

    Available in a wide range of styles, they are a neat and effective way to add easy control of light and heat in rooms with large glazed panels. They save on alternative installations with expensive glazing and also remove the irritation of cleaning external blinds.

    Integral blinds make the perfect addition to bi-fold doors, windows or conservatories in both residential and commercial settings. Available in a range of subtle to vibrant colours, our Italian styled integral blinds come in Venetian (horizontal slats) or pleated (textured pleated fabric) styles. We also offer quick installation and a fantastic 5-year guarantee for complete peace of mind.
