Horizontal Sliding Windows
Features of our horizontal sliding windows
Our windows provide the sought-after stylings of traditional steel with all the acoustic, thermal and energy-saving benefits of double-glazed aluminium.
Our aluminium windows offer the slimmest frames on the market, granting larger viewing angles without compromising on customisation, heating efficiency or style.
Our horizontal sliding aluminium windows are fully customisable, available in your choice of over 200 colours, with optional trickle ventilation for added temperature regulation and optional child-safe window restrictors.
With removable panels for simple cleaning and replacement, as well as an integrated locking system, upkeep is simple – extending the lifespan of your windows and ensuring a premium look and feel at all times.

Bespoke fitted horizontal aluminium windows
Designed and engineered in the UK for over 30 years, The Heritage Window Company’s skilled team has mastered the art of bespoke window manufacturing.
Our expert team have the ability to design and fit horizontal sliding windows to properties of any age or style, thanks to our custom manufacturing capabilities.
All our horizontal slider windows are available in two, three, four or five-panel configurations, with brass rollers as standard – ensuring effortless sliding for decades to come.

Horizontal sliding secondary glazing
The Heritage Window Company can also assist homeowners with the addition of bespoke secondary glazing for horizontal sliding windows.
An ideal solution for older properties, where the capacity for replacing window frames might be limited by listed building restrictions, our secondary glazing service involves adding an additional pane of glass to your existing window to reduce noise from outside.
Our superior secondary glazing offering provides glazing of up to 10.8mm, so you can get the perfect level of insulation for your home.
Horizontal windows for heritage properties
However, if you live in a period or heritage property that isn’t limited by listed building regulations and wish to upgrade your windows, horizontal sliding aluminium frames are a perfect choice.
Aluminium is a direct upgrade from traditional steel, replicating the aesthetic with the added benefit of thinner frames, enhanced customisability and superior secondary glazing options.
Our secondary glazing will help regulate heat in the home throughout winter and summer, lowering energy bills. It will also be more durable, better insulated against sound and is available with anti-glare properties, improving your home experience.
We have extensive knowledge of fitting aluminium windows in conservation areas and heritage buildings, with a skilled team that can advise on any questions you have regarding the age of your property and the service that you require.
