Creating a Juliet balcony with vertical sash windows

A glass wall and a balcony in the same minimal windows glazing system.

Natural light in luxury homes highlights the high-end interior design elements. minimal windows® glazing systems provide the ability to increase the natural light, with slim framed systems such as sliding glass doors or the fully first tested pivot door on the market.

These glazing systems can be used like an extension or as oversized glass walls. Both ways improve the living space because natural light creates the illusion of a much larger living space.

minimal windows® manufactures bespoke glazing system for a range of modern designs and projects. One of the systems is a vertical sliding sash window, something now seen in many home which is a shame because these unique glazing installations can have massive benefits for any project. 

The minimal Vertical Sash window can be specified as a double-height glazing installation, used as an entry point or be used to create a modern Juliet balcony design.

Vertical Sash Window

minimal windows® vertical sash window system has a unique opening style. Vertical sash windows can be double, or triple glazed and the slim aluminium frames provide sightlines from just 21mm for doubled glazed. Maintaining sightlines of 26mm for triple glazed systems. Slim frames provide a clear view without any obstruction.

These large sliding glass windows can reach sizes up to 4m wide, 8.5 m2 per vertical sliding sash for double glazed and 4.5 m wide, 12 m2 per vertical sliding sash for triple glazing. The glass thickness will be between 34mm and 56mm depending on the glass specification. Automation can be specified for a smooth opening in larger sizes.

More glass options are available on request, such as switchable privacy glass, a technical glass solution that offers privacy at the touch of a button. This type of glass is good match for someone who do not want curtains or doesn’t want to disturb the minimal aesthetics of a luxury home. The transparency can be manageable and the glass lets the natural light in during the day, offering privacy at night.

We are currently working on tow projects which use a vertical sliding sash window that creates a Juliet balcony when open. See below for a site picture and details on how to specify this!

Juliet Balcony

Juliet balconies usually have a balustrade installed on the outside of the balcony door. minimal windows® can provide an alternative option, the most modern Juliet balcony with more than one functionality.

minimal windows® vertical sash window in a two-pane configuration is the best option for creating a glass wall and a balcony in one glazing system. The vertical sliding system allows one of the panels to slide down over a fixed pane. When the vertical sash window’s top pane slides down, it creates a modernist Juliet balcony design. With this solution there is no need to have an integrated balustrade, which disturbs the view and natural light of the living space.

This balcony solution is good for upper floors which cannot have terraces or larger balcony areas. Juliet balconies offers more space to the bedrooms because of sliding glazing system. The slim frames of the vertical sash window allow tonnes of natural light to flood the internal living space, enhancing the interior design as well as general wellness.

The glass would need to be designed and tested to meet same requirements as a glass balustrade acting as a balcony barrier, ensuring its suitability for use as a balcony.
