    uPVC casement windows in Tonbridge, Rochester and Canterbury

    uPVC casement windows are one of the most cost-effective choices for new windows, this is because modern uPVC can be easily manufactured with streamlined processes nowadays. Although, the lower price tag doesn’t mean that it compromises on performance. Our advanced uPVC window profiles use a multi-chambered system, meaning it traps the heat inside and stops cold elements from entering, ensuring a comfortable temperature inside. They can last for at least 35 years without needing any maintenance, and won’t rot, warp or fade, thanks to a protective outer coating.

    With uPVC casement windows, the design options have no limit! They can be finished in over 150+ RAL colours and a number of authentic woodgrain finishes, so they can easily achieve both a contemporary style and a traditional aesthetic.

    Slimlime aluminium casement window designs

    High-performance aluminium casement windows offer distinctively thin framed designs that no other material can achieve. The slim-framed appearance will effortlessly add a modern aesthetic to any home, whilst letting in more natural light for a brighter room. It also means you can benefit from greater views of the outdoors.

    Our ultramodern aluminium windows use a thermally broken profile which breaks up currents of air, resulting in exceptional thermal performances. This innovative design also helps to keep external noises out of your home. The powder-coated frames are finished in an anti-fade coating, keeping them looking like new for over 45 years. They don’t require any maintenance, so they’re an ideal solution for busy homeowners.

    You can choose from 150+ RAL colours and a variety of woodgrain effects depending on your personal tastes. With their uniquely smooth frames, they’ll add kerb appeal to your home.

    Window buying process

    Energy efficient double glazed casement windows

    Our double glazing, comfort glass and secondary glazing options will all heighten the thermal performance of the window. Double glazing and comfort glass designs use advanced glass panels that surround argon-gas filled chambers which eliminate energy wastage. Our secondary glazing is also able to increase the energy efficiency of casement windows in homes where building regulations restrict home improvements. By applying an additional pane of high-performance glass, they’ll keep the warmth inside.

    A window upgrade is an excellent way to improve your home’s environmental impact as you’ll need less energy to warm it up, and you’ll also see reductions in your heating bills. Depending on your chosen style and material, A++ energy ratings and U-values of 0.8 W/m2K can be achieved. We incorporate a number of features to maximise their thermal abilities, including warm edge spacer bars and beaded frames, ensuring that the heat is unable to escape from the room, and draughts won’t be able to enter for a comfortable interior all year round.
