About Us
Report
Back in 1968 Derrick Smith founded City Sound, at a time when secondary glazing was virtually unknown, despite the growing problem of old Victorian sash windows in London buildings. Although beautiful, these sash windows were often poorly fitting and allowed in all the noise, draughts and dirt of a growing city.
Window Styles
Report
Find below a few examples of our most popular window styles. Our sash style windows incorporate our unique EASY CLEAN system that is exclusive to City Sound. Give us a call on 020 8523 3210 or email us for more information on all the other style options we offer. Vertical sliding sash windows are by far the most popular style of secondary glazing.
Sash Windows Vertical sliding
Report
Commonly called "Vertical sliding sash windows" within the industry, sash windows are by far the most common window style. For this reason of course, our secondary glazing sash style windows are equally as popular. Consisting of two panels (top and bottom) that slide up and down, our sash windows are counter balance with pre-tensioned springs to hold the weight of the panels.
Horizontal Sliding Windows
Report
The most versatile of all the styles available, horizontal sliding windows (side to side sliding) can be manufactured with 2, 3 or 4 sliding panels. This style of secondary glazing is a perfect match for Crittal windows. The individual sliding panels slide with immense ease, allowing unobstructed access to the external windows.
Fixed Lift Out
Report
An alternative to screw fixed units, fixed lift out windows have a removable glass panel that can be easily lifted out of the master frame to facilitate access to the external windows. This style of window is often used on external windows that are very rarely used or in air-conditioned offices where cleaning between the windows needs to be facilitated.
