Box Sash Windows
Box Sash Windows, also known as Vertical Sliding Windows, Vertical Sliders or Victorian Sliders, are a traditional style of window which are most commonly found in older properties. Traditionally they are manufactured from timber. Box Sash Windows are an elegant window design and are very popular choice in period homes around the Country. Their design is very sophisticated and provides extra charm and style that just cannot be achieved using standard casement windows. Real timber windows are very expensive, and require maintenance, including painting. They are also known to expand and contract in temperature and weather extremes, so the majority homeowners nowadays look for a more affordable solution such as uPVC Vertical Sliders, or uPVC Box Sash Windows.
At Composite Doors Cardiff Limited, we have invested time researching and testing out products to find the best of each class. We feel that ECOSlide offers the best solution to uPVC Box Sash windows. As standard, all windows are provided a-rated, with toughened security glass and high performance locking systems, plus they look fantastic and come in a massive range of modern and traditional colour. ECOSlide were winners of the Nation Fenestration Awards in 2019 and 2020!

D Handles
These optional easy-grip handles can be used in place of pole eyes or sash lifts and can be fitted externally on the bottom of the top sash for ease of operation.
Toughened Glass
(Top & Bottom as standard)
ECOSlide vertical sliding sash windows feature double glazed sealed units with toughened glass in both top and bottom sashes, for enhanced safety and security.
High performance double glazed insulated glass units are 24mm in thickness (outer pane 4mm, airgap 16mm, inner pane 4mm) for optimum thermal efficiency.
Trickle Vents
(Optional Extra)
Predominantly positioned in the top sash, but can be placed in the head upon request. If the trickle vent is placed in the head of the frame, an add-on profile to the top of the window may be required.
Standard Colours available: White, Grey, Grey/White, Golden Oak, Golden Oak/White, Black, Black/White, Rosewood, Rosewood/White. Spayed colours: Cream, Cream/White, Irish Oak, Irish Oak/White, Chartwell Green, Chartwell Green/White.
Cills & Security Bar
(Fitted as Standard)
The signature “anti-jemmy” security bar feature cannot be upstaged. The ECOSlide cill gently slope to efficiently shed and drain rainwater away from window. The Security bar is a integral part of the window cill which significantly increases security, to help prevent potential intruders using tools or excessive force to try and lever open the bottom sash and gain entry.
Attention to detail
It’s the little details that help make ECOSlide sash windows as authentic as possible. Our 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.
