Key Product Features
Traditional homes require traditional windows. Hampshire based KJM’s collection of vertical sliding sash windows perfectly suit Victorian style homes, many different types of older homes and indeed some modern homes too. We can install timber and uPVC versions and the results can look stunning with either system.
Our sash windows of choice are manufactured from the Roseview Collection and are manufactured using uPVC. We also offer a timber sliding sash from our Dempsey Dyer and George Barnsdale range. These can be manufactured with traditional weights and pulleys.
Excellent System Performance
The Veka Vertical Slider was one of the first on the market to be given an Energy A rating. These windows have a tilt back facility for easy cleaning, run through horns and optional travel restrictors to allow you to leave your windows open securely, as there is only a small gap left at either the top or the bottom.
Alternatively, choose from the Ultimate, Heritage and Charisma Roseview windows and create the perfect level of traditional and authentic sliding sash windows. Tailored to every budget and specification, you can benefit from authentic solid timber looks, replica timber appearances or modern uPVC designs. Offering a traditional appearance with modern performance, you can enjoy weatherproofing, sound insulation and incredible thermal performance no matter what you choose.
Additionally, filling the gap with argon gas between the panes of glass within these designs increases the thermal performance, whereas, in a sealed glass insulating unit, air currents between the two panes of glazing carry heat to the top of the unit and settle into cold pools at the bottom. Using argon gas between panes minimises the convection currents within the space, so the overall transfer of heat between the inside and outside decreases.START YOUR QUOTE
Astragal Bars & Low E Glass
Astragal Bars can be fitted to any product by externally facing the glass to enhance the look of windows, doors and conservatories while giving them the traditional Georgian appearance of individual panes. Using interbars on the double glazed sealed units gives the window an appearance of multi-panes.
Additionally, high performance Low-E (low emissivity) glass is designed to reduce heat loss and must be used on energy rated windows. There are two types of Low-E glass: hard coat and soft coat, we use soft coat glass as it gives better light transmission, better U-values and enhanced clarity and neutrality over hard coated glass.LEARN MORE
Ultimate Rose Window
Every detail of the Ultimate Rose has been designed to replicate the charm and character of a timber sash window. With slim timber-like profiles and an industry leading 35mm meeting rail, no other sash window can compete with it on style and authenticity. With period features as painstakingly detailed as joinery-style mechanical joints, a deep bottom rail, run-through horns and external putty lines, it would take an expert to spot that it’s uPVC.
You won’t find any welds on an Ultimate Rose – everything is fully mechanically jointed. Using custom-designed jigs, blocks and brackets, every join on the frame and sashes is finished as a butt joint – just like a timber window. What’s more, the frame is joined horizontally while the sashes are joined vertically. Not only does this add strength and rigidity, it accurately mimics the way original timber sashes were joined.

Vertical Sliding Sash Window Benefits
Sash windows are an inherent part of British architectural history and were introduced in the late 17th Century. A traditional sliding sash window is usually made up of two sashes that slide up and down, modern ones can also tilt for easy cleaning. They were commonly used in Georgian, Regency and Victorian properties.
The original timber window was counter-balanced so the weight of the glazed panel was balanced by a heavy steel, lead, or cast-iron sash weight concealed within the window frame, this means the sash weight is connected to the window by a braided cotton sash cord, or a chain, that runs over a pulley at the top of the frame. Modern uPVC sash windows are manufactured with spiral spring-type balances.
Our sliding sash windows provide customers with the ultimate level of customisation. Foiled finishes such as wood effect and chalk are available to provide a timber like appearance on the uPVC windows. By using excellent quality finishes, all our colours are fade resistant and should never need touching up during its product lifespan. For our full list of colour options, contact us today.

Frequently Asked Questions
Can you get uPVC sliding sash windows?
Yes you can. uPVC sash windows or vertical uPVC sliding sash windows have a classic design and elegant appearance that add a traditional charm to character homes, especially from the Victorian era. uPVC windows are considerably cheaper than timber and are designed to look and function exactly like the traditional sash window. Features including sash horns, grained profiles and traditional furniture really do make it hard to tell the difference.
How does a sliding sash window work?
Sash windows normally comprise of two vertically sliding sashes, the top one sliding down and the bottom one sliding up, meaning you are left with approximately half the opening as a maximum. This can be some at the top and some ventilation at the bottom at the same time. Modern windows normally have a tilt back facility for cleaning and can have a lock to limit the opening to enhance security and easy access from the outside. This provides peace of mind for ground floor windows.
Can I replace sliding sash windows with casement windows?
Before changing the design of any window it is always worth thinking about the character of the property. Is the property in a conservation area or is the building listed? If this is the case then it may not be possible to change to modern windows without the need of planning permission. Even changing from single glazing to double glazing can be a problem with listed buildings.
Sash windows are generally different dimensions to a conventional modern windows, so casements may not work so well with the dimensions of the older style of window. Finally changing the style could have an impact on your house value and could also make your home less desirable to future owners, if you decided to sell it.
What's the difference between sliding sash windows and casement windows?
Sash windows slide vertically, casement windows generally operate like a door, they can open either inwards or outwards. Older sash windows are usually harder to clean although most new ones can be specified with a tilt back option for easier cleaning. The operating mechanism of a sash window is more complex than a casement window.
How much does a sliding sash window cost?
An average sash window is normally around 900mm in width and just over 1500mm tall, however the sizes can be much bigger and even smaller, this of course has a bearing on the installed cost. As a guide a uPVC sliding sash window start at around the £900 mark, a timber window is in excess of £2200, both prices include fitting and VAT.
How can sliding sash windows be made more thermally efficient?
At standard, the double glazing on our sliding sash windows already provides an ‘A’ WER rating. However, with the addition of warm edge spacers, argon gas filled units and low-e glass, you’ll be able to increase thermal performance and reduce condensation. Through these extras, you’ll see savings on heating costs and improved light transmission in your home.
