What’s the difference between Residence 9 and Residence 7 windows?
Residence 9 Multi Chambered Window
Residence 9 has a 100mm-deep, nine-chamber profile designed specifically to combine the appearance of a traditional flush sash timber window with the performance of a modern high-performance window system.
The increased profile depth provides the space required to accommodate larger glazing units, including 44mm triple glazing, while the CEN A wall thickness and additional screw-retention chambers provide increased strength and support around the hardware.
With a 44mm Argon-filled triple-glazed unit, Residence 9 can achieve an overall window U-value of 0.8 W/m²K. With a 28mm double-glazed unit, the stated overall window U-value is 1.2 W/m²K. The exact performance will depend on the glazing and window specification selected.
Triple glazing with Residence 9
Triple glazing uses three panes of glass separated by two sealed cavities. The additional pane and cavity can improve thermal insulation and help create warmer internal glass surfaces compared with standard double glazing.
Residence 9 is designed to accommodate the additional size and weight of a 44mm triple-glazed unit, making it possible to combine a traditional heritage appearance with high levels of thermal performance.

Hand Finished Ironmongery Options
The joints of our R9 window are hand crafted and combines the repeatability of the modern machining process with the eye of a craftsman. You can personalise your Residence 9 windows with a choice of handles. The monkey-tail and pear drop designs were popular designs of the period. If your room is more contemporary you can also specify more modern finishes like Chrome, Brass or a Pewter Patina.
With your Residence 9 window, you can specify traditional butt hinges to maintain original features. Modern windows often lack this character as the hinges are hidden. The ironmongery is crucial to maintaining an authentic kerbside appearance. To view installed ironmongery, visit our product gallery page.

The Timberweld® Advantage
Timberweld® technology is a true game-changer for Residence 9 windows, flawlessly combining the authentic charm of traditional timber with the efficiency of modern manufacturing. While early Residence 9 windows relied on complex mechanical jointing and heavy glass bonding to replicate a 19th-century mortice and tenon joint, Timberweld revolutionises this process. It cleverly fusion-welds the unseen internal chambers for robust strength while leaving the straight-cut, timber-effect edges perfectly visible on both the inside and outside. Because this innovative method completely removes the need for structural glass bonding, the window frames are significantly lighter and easier for installers to fit and adjust for perfect sightlines. Best of all, if a glass pane ever breaks, it can be quickly replaced just like a standard uPVC window, saving you from the immense cost and hassle of having to replace the entire sash.

The overall U-value depends on the exact window and glazing specification. With a 28mm double-glazed unit, Residence 9 can achieve an overall window U-value of 1.2 W/m²K. A 44mm Argon-filled triple-glazed specification can achieve an overall U-value of 0.8 W/m²K.

Can Residence 9 windows have triple glazing?
Yes. Residence 9 is designed to accommodate 44mm triple-glazed units, making it possible to combine traditional flush-casement styling with high levels of thermal performance.
Triple glazing can improve thermal insulation and comfort, although whether it is worthwhile depends on the property, existing windows, heating system and overall energy-efficiency objectives.
For more information, read our guide to triple glazing and triple glazed windows.
Is Residence 9 suitable for period properties?
Yes. Residence 9 was specifically designed to replicate the appearance of traditional timber flush sash windows and is particularly well suited to Victorian, Edwardian and other period properties.
The range of heritage colours, traditional hardware, Georgian bars and flush detailing allows the windows to be specified to complement the character of the property.
Can Residence 9 windows be used in conservation areas?
Residence 9 can be suitable for properties in conservation areas because of its traditional appearance and heritage detailing. However, requirements vary between properties and local planning authorities.
If your property is in a conservation area or is listed, we recommend checking the relevant planning requirements before ordering replacement windows. KJM can also discuss the available options during your survey.
Are Residence 9 windows maintenance-free?
Residence 9 requires significantly less routine maintenance than traditional painted timber windows. The uPVC construction does not require regular sanding, painting or treatment to protect it from the elements.
Normal cleaning and occasional checks of the hardware, seals and drainage are still recommended to keep the windows performing properly.
How secure are Residence 9 windows?
Residence 9 is designed with security in mind and incorporates features including a substantial profile, reinforced hardware fixing points and modern locking systems.
The exact security specification depends on the hardware and configuration selected. KJM can advise on the appropriate specification for your property

Residence 9 is available in a wide range of traditional and contemporary colours and wood-effect finishes. Options include heritage shades such as Painswick, Cotswold Green and Eclectic Grey, alongside wood-effect finishes and dual-colour combinations.
The available colours and finishes can vary, so we recommend viewing the current Residence 9 colour range when choosing your windows.
Can I choose traditional handles and hardware?
Yes. Residence 9 can be specified with a range of traditional-style hardware designed to complement its heritage appearance. Options include monkey-tail and pear-drop handles, butt hinges and other period-inspired details.
Hardware finishes can be selected to coordinate with the colour and style of your windows.
What is Timberweld® on Residence 9 windows?
Timberweld® is the manufacturing process used to create the appearance of traditional timber joints while retaining the benefits of modern uPVC construction.
The process helps create authentic-looking external joints without relying on the same construction methods used for traditional timber windows.
How much do Residence 9 windows cost?
Residence 9 is a premium window system, so it generally costs more than standard uPVC replacement windows. The final price depends on factors including the size and number of windows, glazing specification, colour, hardware, decorative details and installation requirements.
Because every installation is different, KJM provides individual quotations following a survey rather than using a standard price per window.

Both Residence 9 and Residence 7 are flush casement systems from the Residence Collection, but they have different profile depths and proportions.
Residence 9 has a 100mm-deep profile and is designed to closely replicate traditional 19th-century flush sash timber windows. Residence 7 has a 75mm profile, providing a slightly slimmer alternative while retaining the flush-casement appearance.
The most suitable option depends on the property, required appearance, glazing specification and available space. See our guide to Residence 9 vs Residence 7 for a more detailed comparison.
Are Residence 9 windows suitable for listed buildings?
Residence 9 may be considered for some listed or historically significant properties, but listed buildings are subject to specific planning and heritage requirements.
If your property is listed, you should check with the relevant local planning authority or conservation officer before replacing the windows. KJM can help you understand the available window options, but planning approval cannot be guaranteed.
