From Draughty Folding Doors to Stunning Triple Sliding Doors with a LandVac Vacuum Glazing and SMARTS Aluminium Collaboration

At CN Glass, when a customer comes to us with a problem, our priority is simple: find the right solution. There are no gimmicks and no hard sell, just honest advice, a personable service, and access to a range of proven glazing products designed to deliver lasting results.

Recently, we worked with a homeowner in Marlow, Buckinghamshire, who was experiencing draughts through their windows and operational issues with a large set of six heavy aluminium folding doors. Built in 2015, the property was relatively modern, yet the homeowners were looking for significant improvements in comfort, performance, and usability.

Initially, the enquiry was focused on replacing a handful of windows. However, through close collaboration between our glazing specialists and the customer, the project evolved into a complete refurbishment of the property’s windows and patio doors. The existing folding door system was replaced with a sleek and practical triple sliding door solution, transforming both the appearance and functionality of the home.

After researching the available options, the homeowners selected LandVac Vacuum Glazing to maximise the performance of their investment. The glazing was installed within a SMART Visoglide Plus aluminium sliding door system, creating a contemporary solution that delivers exceptional thermal and acoustic performance.

The results have been outstanding.

Not only has the installation enhanced the property’s energy efficiency, but it has also completely transformed the connection between the home and the garden. The new triple sliding doors provide expansive, uninterrupted views while creating a more comfortable and peaceful living environment.

LandVac Vacuum Glazing represents the next generation of glazing technology. It outperforms traditional double glazing, triple glazing, and many other vacuum glazing products while maintaining an incredibly slim profile.

The system consists of two panes of toughened glass separated by microscopic pillars and a vacuum layer. This advanced design virtually eliminates heat transfer through conduction and convection, delivering exceptional insulation performance.

Key benefits of LandVac Vacuum Glazing include:

  • Ultra-slim profile of just 8.3mm, less than half the thickness of many conventional double-glazed units.
  • Outstanding thermal performance with U-values as low as 0.4W/m²K.
  • Enhanced acoustic insulation, reducing external noise by up to 39dB.
  • Improved energy efficiency that can help lower heating costs.
  • A discreet appearance that preserves the character of the property.
  • Long-term performance designed to last 25 years or more.

For homeowners looking to improve comfort, reduce energy consumption, and minimise outside noise, LandVac offers an innovative solution that combines performance with aesthetics.

Following completion of the project, our customer commented:

“The triple sliding doors are already showing a huge improvement, and we are looking forward to feeling the benefits come the winter. Our experience with CN Glass has been excellent, and so many people have already commented on the change in our property.”

Feedback like this is exactly why we do what we do. By listening carefully to our customers’ needs and recommending the right products, we help homeowners make informed investments that deliver real benefits for years to come.
