A sash window is made of one or more movable panels or "sashes”. The term is used almost exclusively to refer to windows where the glazed panels are opened by sliding vertically, or horizontally.
The eurosash sliding sash window is designed to suit various styles of properties and comes with the widest choice of colours available on the market. The eurosash is versatile enough to compliment elegant period-style homes as well as modern dwellings and commercial properties. It has all the benefits of modern technology while still retaining the charm of traditional sash windows.
Sash windows used to be made of wood and as a result they brought problems and were high maintenance. Traditional problems with wooden sash windows include rot, swelling or distortion of the woodwork, rattling in the wind (due to shrinkage of the wood), and problems brought on by careless application of paint. The sliding mechanism makes sash windows more vulnerable to these problems than traditional casement windows. Sash windows are relatively high maintenance.
However in recent years, uPVC sash windows have become available. These aim to replicate the aesthetic qualities of traditional sash windows, while overcoming many of the shortcomings - especially regular maintenance and painting, and energy inefficiency.
A significant advantage of sash windows is that they provide efficient cooling of interiors during warm weather. Opening both the top and bottom of a sash window by equal amounts allows warm air at the top of the room to escape, thus drawing relatively cool air from outside into the room through the bottom opening.
