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. 

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.
