Putting style and beauty back into your home

Closely resembling the look of traditional timber box sash windows, our EcoSlide vertical sliders offer the character and charm of a traditional sash window with the long term performance of modern production materials. Our vertical sliding sash windows have excellent thermal properties - they are A rated as standard, so when upgrading your windows you will conserve heat and reduce your heating bills.

Superior weathering performance will ensure your new windows retain their pristine appearance year after year. So you can have the best of both worlds; the charm and character of a traditional vertical slider and the benefits of a modern uPVC window, with their low maintenance attributes.

We have been installing ECOSlide uPVC sliding sash windows for 18 years. In 2020 we won both the Installation of the Month (July) and Installation of the Year with our fantastic Roehampton job - you can read the full article here.

Choosing our sliding sash windows means you can enhance the look of your home without compromising on style, security or energy efficiency. Nothing looks quite as good as a real sash window.

To complete the timber-like appearance, our windows incorporate the same stylish features found on original timber sash windows such as astragal bars, decorative sash horns and traditional-style operating hardware. The jambs, sash sections and meeting rail are all engineered to look just like a timber sash window, giving you truly authentic looking new windows.


Primarily functioning like a wooden box sash window, both top and bottom sashes slide up and down to suit. Convenient and simple to operate, the two sliding sashes work independently of each other on a balanced load mechanism, designed to hold the sash at any height.

Sashes feature an inward opening tilt facility to allow easy and safe cleaning of the outside frame and glass from inside. This is particularly useful for second storey windows or if positioned in a hard to reach place, such as above a conservatory.

Find your ideal look with a wide choice of colour options

Timber box sash windows were always painted and you can replicate this look with solid white and cream colour options. If you would prefer a more natural wood effect, the crystal white, cream, golden oak and Irish oak foils give a realistic woodgrain appearance that mimics the grained texture and appearance of an original timber window. We also offer the option of a colour on the outside and white on the inside - choose from Chartwell green, anthracite grey, rosewood, black brown, cream, golden oak and Irish oak. With this option you can have the external colour you like, whilst maintaining a white interior to better suit your home’s decoration.


Are you after something more unusual or do you want to match up a particular colour? Our EcoSlide paint service enables your sash windows to be spray painted to match virtually any RAL code or colour. It is applied to the highest standards and will provide a unique and colourful addition to your home.

You can personalise your EcoSlide vertical sliding sash windows and colour co-ordinate them to match your property or just to suit your own personal tastes.


A range of styles are available to match your existing windows as closely as possible and maintain the character of your home.

Arched and swept head sash windows are manufactured according to your exact requirements, including the eye-catching Gothic and Norman style arches. Other more standard design options are available with external astragal bars for an authentic glazing bar look.

Safety and security for your home

Add the finishing touches to your new windows with traditionally-styled vertical slider hardware. Pole eyes, tilt knobs, sash lifts, sash locks and travel restrictors are fitted as standard, but we can also offer D handles if required.. All hardware is available in chrome, gold, white, black or satin chrome to complement our range of colours. Other additional options are available such as Georgian or Astragal glazing bars and trickle vents, to give your new windows a truly authentic and classical vertical slider look.

In addition to this, our EcoSlide uPVC sliding sash windows are designed to be extremely safe and secure. High performance locking systems keep your home safe from potential intruders to give you extra peace of mind. For added safety we also offer the option of a “Fire Egress” window design to provide emergency escape.
