Striking Double Height Glazing Elevations

Incorporating double-height glazing into your home can really open up a space and maximise natural light flow into the home.

This can be in the form of oversized sliding glass doors, a vertical sash window or using minimal windows systems in conjunction with structural glazing.

minimal windows glazing systems can be automated and integrated with smart home automation for a modern glazing solution that can be opened and closed with extreme ease.

Using specially engineered glazing systems with modern glazing technologies, we can now provide homeowners with double-height glazing systems that are unmatched in both performance and design.

Double Height Sliding Glass Doors

The maximum height of a slim sliding door depends on the selected system, pane area, glass weight, building location, wind exposure and structural support.

The minimal windows® 4+ system supports sliding doors up to 4.5m high as a standard product configuration. For projects requiring conventional horizontal sliding panels up to 6m high, the minimal windows® NGS range accommodates panels up to 18m² and 1,500kg. Explore our 6m tall sliding door systems for product capabilities and specification information.

Where project conditions allow, selected minimal windows® systems can also be engineered beyond their standard dimensions. Read our guide to 6m tall sliding doors for an explanation of the wind loading, pane proportions, structural support, automation, transport and installation requirements involved.

Portland Road features a minimal windows® 4+ sliding glass door measuring 5,770mm high. The system was installed beside a double height void within a terraced London home, creating an uninterrupted glazed elevation across two storeys.

The relatively sheltered location and project-specific engineering allowed the sliding door to exceed the standard 4.5m system height while retaining the slim framing associated with minimal windows®.

Looking to understand how doors can achieve heights of 6m and beyond? Read our guide to 6m tall doors, covering engineering requirements, system capabilities and real-world project examples.

Kingston Road uses a three-track, three-panel minimal windows® sliding door measuring approximately 4.6m high and 3.8m wide. Reinforced 21mm interlocks and an integrated drainage channel allowed the system to be adapted beyond its standard dimensions.

The double height sliding doors bring natural light into the kitchen and dining area while emphasising the height of the integrated mezzanine.

Double Height Vertical Sash Windows

Our minimal Vertical Sash window system tends to be specified as a double-height glazing installation as this way large panes can be used to create a stunning focal point of a home that also acts as a functional entrance and exit.

This sash window system creates horizontal openings that are ideal for large glass facades including double-height glass elements.

One of our projects features a large specialist glazing package designed by our glazing partners IQ Glass UK. The rear of the home has a double height minimal Vertical Sash window that is 4.2m in width and reaches just over 6m tall.

The system is a three pane vertical sliding window and the centre pane is fixed. The top and bottom panes are moved manually to meet in the middle, leaving a space at the bottom that connects the garden and internal living space.

Air is able to flow freely into the new build home from above and the slim aluminium framing on this oversized vertical sliding window system causes minimal obstruction to the flow of natural light and provides stunning, uninterrupted views of the outdoors.

Our Camlet Way project uses three identical automated minimal Vertical Sash windows to create bright light internal double height living spaces. The windows reach just over 6m in height and are 1.4m each in width.

The bottom panes of the sash windows can be side upwards with ease to create a large opening that can be used to access the stunning garden at the rear of the home.

Double Height Glass Facades

Double height glass facades can be created using a wide range of minimal windows glazing systems. Our luxury aluminium glazing systems can also be used in conjunction with structural glazing resulting in striking elevations.
