    uPVC sliding sash windows in Tonbridge, Rochester and Canterbury

    Our uPVC vertical sliding sash windows combine the traditional timber style with the modern performance provided by today’s uPVC technology. Whilst uPVC is usually the more affordable option because it can be much more easily manufactured, thanks to the streamlined processes, it still offers exceptional performances.

    uPVC window frames are made with a pioneering multi-chambered frame which is able to break up the airflow. So in the winter, it will stop the cold elements from entering and in the summer they’ll keep the heat out. This multi-layered design is also beneficial for weather resistance as it’s robustness is heightened, so it will keep your home protected from even the harshest weathers. We finish our uPVC window frames in a protective coating, so that they won’t fade, rot or split over their lifetime, which is at least 35 years. They’re maintenance free, making them the ideal window upgrade for busy homeowners.

    Our uPVC sliding sash windows replicate the traditional timber design, using similar joinery techniques and a woodgrain textured finish to attain the heritage aesthetic. With over 150+ RAL colours and a number of authentic woodgrain effects, it’s an incredibly versatile window solution.

    Double glazed sliding sash windows will improve energy efficiency

    If you live in a period property with its original sash windows, you may have noticed that they struggle to retain heat and let the draughts in. That means it could be time to replace your windows. Whether you choose our uPVC sliding sash windows, you’ll instantly benefit from improved thermal performances in your home. Dependent on the specification, they can achieve A+ energy ratings and our advanced double glazing boasts U-values as low as 1.2 w/m2K. This means that energy wastage will be reduced, so you’ll be able to save money on your heating bills.

    We use pioneering double glazed panels which involve two panes of glass that surround an argon-gas filled chamber. This effectively breaks up currents of air, keeping your home at a comfortable temperature all year round.

    Upgrade your home’s security with durable windows

    If you’re looking to heighten your home’s security, then our sliding sash windows are the ideal solution. Because of their vertical opening, they have their own security features to ensure that your property is protected. This includes sash fasteners to stop the window from opened from the outside, sash window stops which restrict the opening of the window sashes and robust meeting rails which keep the window resilient to forced entry. Safety latches are also included which enables the sash to tilt inwards.

    Our range of durable sash windows have been tested to strict security regulations. For homeowners looking for even further protection, we can include additional security hardware into your bespoke design.
