 Trustindex verifies that the original source of the review is Google. Having used KJM as our primary glazing supplier, at G and R Cousins Building Services, for well over ten years, I cannot fault their product range or reliability. From standard Profile 22 uPVC or Smarts aluminium window supply to high-end aluminium bifold doors to roof lanterns, they deliver exactly what we need. It makes a massive difference having a local supplier where we can source both our standard and specialist products under one roof.

 Trustindex verifies that the original source of the review is Google. Can't rate them highly enough. Answered the phone, booked in a visit when it was easy for me and instead of just looking at the issue, he just went and fixed it. 3 years we've put it off when all this time we should have just phoned KJM. Thanks Mark!

 Trustindex verifies that the original source of the review is Google. We chose to use KJM to replace all of our windows and doors as we had used them in the past to replace patio doors with great success. We were not disappointed this time around either.
From the initial meeting with Charles in the Andover showroom to completion, overseen by Simon, all was excellent. Lester and Zak who were our main fitters worked in a conscientious way; Good communication and attention to detail prevailed. Approachable and friendly, nothing was too much trouble for them. We would have no hesitation in recommending KJM
Thank you!

 Trustindex verifies that the original source of the review is Google. What a great team. Our new triple glazed windows have been fitted and we are very happy. Charlie and Ryan did a wonderful job. Both very friendly and professional and cleaned up after themselves. Only took two days and minimal disruption to ourselves. Thank you KJM for your superb service.

 Trustindex verifies that the original source of the review is Google. Appointment made for a faulty locking mechanism to be fixed on a double glazed window. This was fixed within 30 minutes of the engineer arriving. Service was quick and efficient.
The only downside to the whole process was that we were given a time of mid-morning and the engineer arrived at 8:55 so a little embarrassing as we were not up thinking of a time of around 10.
Having said that the service was excellent.

 Trustindex verifies that the original source of the review is Google. We were recommended KJM Windows by someone in our neighbourhood who had recently had their windows replaced, and we’re so glad we took their recommendation!

From our very first contact with Charles in Sales, he was fantastic at guiding us through the different options and quotes, making the whole process clear and straightforward.

Andy and Kerry, who carried out the survey and technical work, were incredibly knowledgeable, thorough and accommodating, taking the time to make sure everything was carefully considered and explained.

Emma, the Installation Coordinator, was brilliant from start to finish. She kept us regularly updated, was always quick to respond to any questions, and her excellent communication meant we never had to chase for an update.

A huge thank you to Zack, Lester and Shae, who did a fantastic job with the installation. They were friendly, polite and professional throughout, always punctual and incredibly tidy. They were a real pleasure to have at the property, and we couldn’t have asked for a better team. They also deserve a special mention for their excellent choice of radio station!

Simon was also fantastic in making sure that any issues were dealt with promptly and efficiently, and that everything was finished to an exceptionally high standard. His attention to detail and commitment to ensuring we were completely happy with the finished result were greatly appreciated.

From our very first contact to the completion of the installation, everyone at KJM has been incredibly helpful, informative and professional, without ever making us feel pressured or rushed.

Overall, we couldn’t be happier with the experience, the quality of the workmanship and, most importantly, the fantastic team behind it. Everyone we dealt with genuinely went above and beyond to make the whole process straightforward and stress-free.

We would have no hesitation in recommending KJM Windows to anyone considering new windows. A truly fantastic company with an excellent team from start to finish.

Flush Casement Design: Inside and Out

One of the defining features of Residence 7 is its flush design, with the opening sash sitting flush with the outer frame and a flush appearance on the inside as well. This creates clean, consistent sightlines that closely resemble traditional timber joinery.

The 75mm-deep profile is designed to provide the proportions and detailing associated with traditional flush casement windows while offering the low-maintenance characteristics of a modern window system.

Residence 7 can also be customised to suit different properties and architectural styles, with options including:

Heritage and wood-effect colours
Traditional-style handles and hardware
Double or triple glazing
Timberweld and other joint options
Dual-colour finishes

This combination of flush detailing and customisation makes Residence 7 suitable for both traditional properties and homeowners looking for a more refined alternative to conventional uPVC casement windows.

What makes R7 different

Technical Specifications

Feature	Residence 7 Specification
Profile Depth	75mm
Chambers	Seven-chamber profile
Acoustic Performance	Depends on the glazing and complete window specification; acoustic glazing options are available
Window Energy Rating	Up to A++ with the relevant specification
Overall Window U-Value	Up to 1.2 W/m²K with 28mm double glazing / 0.8 W/m²K with 44mm triple glazing, subject to specification
Glazing Options	28mm double glazing or 44mm triple glazing
Maintenance	Low maintenance; no routine painting required

The final performance of a Residence 7 window depends on the complete window, glazing and hardware specification. Where acoustic performance is a priority, KJM can advise on suitable glazing options for the property.

Timberweld: Traditional Appearance with Modern Construction

Residence 7 can be manufactured using Timberweld technology, which creates clean, welded joints designed to complement the flush appearance of the window.

The process provides consistent, neat joints while retaining the traditional proportions and detailing that are central to the Residence Collection’s design.

Timberweld also allows the window to be manufactured and supplied without relying on the traditional mechanically jointed construction associated with older timber-style windows.

For homeowners replacing existing windows, the welded construction provides a clean finish while the modern frame and glazing options deliver the low-maintenance characteristics expected from a contemporary window system.

If a replacement glass unit is ever required, the glazing can be replaced without replacing the complete window frame, subject to the specification and installation.

Modern Security Features

Residence 7 incorporates modern locking and hardware options designed to provide a secure window solution for the home.

The 75mm profile includes dedicated areas designed to provide secure fixing for window hardware, while multi-point locking systems can be specified as part of the overall window configuration.

The final security performance depends on the exact window design, hardware and locking specification selected.

Where a specific security standard or certification is required, KJM can advise on the available specification for your property.

Residence 7 vs Residence 9: The Complete Comparison Guide

A 75mm Seven-Chamber Profile Designed for Modern Glazing

Residence 7 features a 75mm-deep, seven-chamber profile designed to combine the proportions of a traditional flush casement window with the performance characteristics of a modern uPVC system.

The profile is designed to accommodate both 28mm double glazing and 44mm triple glazing, allowing the window specification to be tailored to the requirements of the property.

With a suitable 44mm Argon-filled triple-glazed unit, Residence 7 can achieve an overall window U-value of 0.8 W/m²K. A 28mm double-glazed specification can achieve an overall window U-value of 1.2 W/m²K.

These figures refer to the complete window rather than the glass alone. Actual thermal performance depends on the precise frame, glazing and hardware specification.

Triple Glazing with Residence 7

Triple glazing adds a third pane of glass and a second sealed cavity to the window. When combined with the Residence 7 profile, it can provide a high level of thermal insulation and help maintain warmer internal glass surfaces.

Whether triple glazing is the right choice depends on the property, existing windows, heating requirements, glazing specification and budget.
