ECOSlide PVC-U sash windows are the cost-effective replacements for traditional timber windows. The affordable alternative to achieving sophistication and charm on period and modern homes.

ECOSlide PVC-U sash windows function like a wooden box sash window, convenient, easy to operate and can hold the sash at any height. Choose from a range of colour and hardware options to complete the look that enhances your home.

  • Enhance Any Home
  • Improved Views
  • Low Maintenance
  • Tilt & Easy Clean Function
  • Various Colour & Foil Options
  • ‘A’ Grade Energy Efficient

ECOSlide PVC-U sash windows function like a wooden box sash window. Both the top and bottom sashes slide up and down depending on your ventilation requirements.

The two sliding sashes, within an outer framework, operate independently of each other on a balanced load mechanism. This is designed to hold the sash at any height. They are convenient and simple to operate and can hold each sash at any height.

Sliding Sash Windows
Easy clean sash windows

ECOSlide PVC-U sash windows feature an inward opening tilt facility, allowing easy cleaning in hard to reach places.

These sash windows only require a quick wipe down with a damp cloth to keep them looking great. Meaning ECOSlide sash windows are also incredibly low maintenance.  And, with the tilt facility, safe cleaning of the outside frames and glass can be achieved from inside your home.


The finer details ensure the ECOSlide sash windows look as authentic as the traditional types. The PVC-U windows are designed to be smooth and sleek with slim profile sections giving a better appearance, which is pleasing to the eye as well as offering improved views from the inside and outside.

To complete the timber-like appearance, our windows incorporate the same stylish features found on original timber sash windows such as run-through sash horns or plant-on horns if required, astragal bars or Georgian bars 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.

Safe and Secure Sash Windows

ECOSlide PVC-U sash windows are designed to be extremely safe and secure. High-performance locking systems keep your home safe from potential intruders giving you and your family extra peace of mind.

For added safety, we also offer the option of a “Fire Egress” window design to provide an emergency escape.


Timber box sash windows were always painted and you can replicate this look with our solid White and Cream colour options. If you want to achieve a more natural wood effect, our 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.

You can also opt to have an outside colour and inside white. Choose from Chartwell Green, Anthracite Grey, Rosewood, Black Brown, Cream, Golden Oak and Irish Oak and have the inside white. With this option, you can have the external colour you want, whilst maintaining a white interior to flatter your property interior.

Arched and swept head windows can also be replaced. These shaped styles are incredibly eye-catching. ECOSlide PVC-U sash windows are bespoke-manufactured to your exact requirements, to maintain the appealing charm of your home.

Further additional design options are available with internal Georgian Bar or external Astragal Bar detailing, to ensure your new windows are truly authentic in style.

Customer Reviews

As a returning customer, I knew I could expect a very high standard of workmanship. I received valuable advice right from the planning application and design stage. The finished product reflects the pride and attention to detail that Luke puts into his workmanship. Despite the scale of the job for such a small flat, disruption and mess was kept to a minimum, with all debris cleared on departure. Once again, a big thank you to Luke and the team at Wenwood!
Customer in WaterloovilleChange of use of dormer from window to French doors
Extremely good workmanship. Mr Bigwood and his team were very efficient and expert at what they do. We were delighted with the finished job. They worked quickly but thoroughly without cutting any corners. The house was left clean and tidy after they had finished and all waste was removed. They were all very friendly and went out of their way to be helpful. I would recommend Wenwood to all who want the peace of mind that comes with finding a really professional company that carries out a quality job at a really fair price.
Customer in SouthamptonReplaced all our windows and doors.
Had this work carried out on behalf of my son who was out of the country at the time. I’m sure he will be very pleased, as I am, with the overall quality of work and the professional manner of Wenwood. Wendy and Luke Bigwood kept me informed throughout. They were a pleasure to deal with and I would not hesitate in recommending this company.
Customer in EastleighReplace guttering, fascia and soffit
I recommend this firm without reservation. Luke Bigwood listened carefully to all my requests regarding a new, bespoke conservatory. He was able to find a way of incorporating every feature that I wanted and was creative in finding appropriate solutions to technical difficulties presented by the particular site. He and his team are extremely hard workers and were always friendly, co-operative and helpful, and they worked to a high professional standard. I’m very satisfied with the final result.
Customer in BournemouthDemolished old conservatory and built new, bespoke conservatory
Luke Bigwood has quoted on and completed 6 separate projects at two different addresses over a two year period. All of the quotes were adhered to, completed on time and with minimum disruption. The quality of materials used and the finished job were of the highest! In particular Luke and his team were most courteous and helpful all times. I and my wife cannot praise his work too highly.

Customer in RomseyComposite door and weather side screen
Luke did a fantastic job fitting the back door, including laying a course of bricks to raise the threshold. He always accommodated our schedules with no problems and even squeezed in an early fitting date, which was appreciated. Would definitely use again.

Wenwood carried out their work to the highest standard, going above and beyond to ensure a faultless job. They even did some small repairs free of charge, which they weren’t obliged to do. They were professional and friendly throughout and cleaned up thoroughly before leaving. I am extremely pleased with the final result and would definitely recommend them to anyone.
