UPVC Sash windows

UPVC Sliding Sash Windows Supplied and Installed

New Sash (Vertical Sliders) Sash windows add a touch of elegance to any property and particularly suit those with an element of tradition. Made with one or more moveable “sashes” They can have cottage bars added to create more than one pane. Our latest range of sash windows uses specially designed steels to enable window sizes of up to 1600mm by 3000mm.

Replacement Sash Windows
Timeless elegance meets modern window design. Camden vertical sliders combine the beauty and elegance of the traditional sliding sash window with the high performance, security, durability and energy efficiency of modern window design and manufacture.

Our Sliding Sash Windows replicate the styling of timber box sashes so accurately that they are often approved for use in conservation areas. With slim sashes, decorative horns, true Georgian bars and a slim mullion section, they actually enhance the styling of a traditional home. They also slide easily and smoothly, putting an end to the sticking and rattling associated with timber and, as an added bonus, they tilt inwards for ease of cleaning and ventilation.

Mock Sash Windows are an attractive alternative to the more traditional vertical sliding sash window. The top hung casement provides ventilation and can also be locked in the night ventilation position. The lower sash is a tilt and turn window, which can be opened inwards for ventilation and easy cleaning.

Our Flush Sash windows are specially designed so that the opening sash of your window sits flush with the outer frame, giving a unique sleek and seamless appearance.

Not only do Flush Sash windows authentically replicate the features of a traditional timber window, they also compliment more modern homes perfectly with their clear lines and minimalist appearance. From the traditional and highly textured Oak to the modern Anthracite Grey, you will find the perfect match for your home.

Our sash windows also bring with them all the benefits of uPVC such as low maintenance, improved energy efficiency and better security.

Capable of achieving U-values as low as 1.4 w/m2K
Camden vertical sliders are fitted as standard with Low Iron/Soft Coat double glazing units which deliver a WER energy ratings of “A” and whole window U-values of 1.4 w/m2K. Windows can be further personalised with the addition of Georgian or Astrical bars. Georgian bars are fitted within the glazing unit itself, whilst Astrical bars are fixed to the outer pane.

Traditional looking
Our sash windows are uniquely designed with a period look and feel, so they preserve your property’s historic charm whilst enjoying all the perks of a modern window.

Vertical Sliding Facility – Both the top and bottom sash can be moved vertically and held in the required position it utilises spring balances rather than the cord and weights used in the old wooden sashes windows and in turn makes the opening and closing of the sashes incredibly easy.

Tilting Facility – As an added feature before fully opening the window the hinge mechanism will hold the sash in at the bottom whilst tilting inwards at the top to give adequate ventilation without the window being fully open. The Sliding Sash Windows feature an easy clean system that allows the Sashes to be cleaned from the inside. The sashes will then tilt in towards the room at an angle and can be operated individually or simultaneously.​

Our sash windows feature key-lockable traditional style fitch locks, as well as additional security features to ensure they are safe, secure and reliable.

Windows Hardware
We use the very best hardware, including top-of-the-range operating mechanisms, which make our hand-built PVCU windows virtually indistinguishable from the timber windows they could be replacing.
