A guide to vertical sash windows where we answer your frequently asked questions.
Vertical sash windows are the vertical version of sliding glass doors, designed as a contemporary window system that is perfect for utilising the oversized glazing trend. These sliding window systems are perfect for contemporary new build and renovation projects, creating double or even triple height spaces that flood the internal living space with natural light.
Pairing smooth action openings with minimalist glazing, the vertical sash windows are designed to slide upwards in a gravity-defying motion. The vertically sliding windows are supported using a hidden pulley system which has been integrated within the design to be completely concealed, using counterweighted technology in configurations with three panes.
A vertical sash window has recently been installed at the IQ Glass showroom, creating a highly glazed façade design that reaches a staggering 6 metres tall.
The three-pane vertical sash window is fully automated, with the top and bottom panes sliding over the middle pane with a seamless smooth motion. The large sliding window system uses minimal windows® aluminium profiles for the slimmest possible design, with a high glass to frame ratio allowing floods of natural light into the showroom space.

What is a vertical sliding sash window?
A vertical sliding sash window is a bespoke glazing solution that has two or three panes with the top, bottom or both moving up and down to create an access point, increase ventilation and can even be used to create a Juliet balcony. This can either be controlled by specialist motors or manually controlled counterweights to move large panes of glass up and down.
What are the configuration options for vertical sash windows?
These sliding window systems are manufactured on a completely bespoke basis, making them flexible by nature. Two and three-pane configurations are the most popular configurations and IQ would look at the project on an individual basis to determine which configuration would be better suited, taking into consideration the location and intended use.
What is the maximum height of the system?
There is no pre-determined maximum height and the vertical sash window can be designed to suit bespoke project requirements, reaching staggering heights to suit client’s individual needs.
How are the glazing panels supported in mid-air?
The large and heavy panels are supported with stainless steel tension rods, which are part of the integrated pulley system.
What happens if the rods were to fail?
There are various backup tension rods that are designed to support the weight of the glass panes in the event of the primary rods failing.
If the vertical sash window is automated, can the speed of the automation be changed?
Yes, this can be tailored to suit the homeowner or architect’s preferences.
When the top and bottom panels are counterbalanced, like at the IQ showroom, does this mean that each panel has zero/ neutral weight?
Yes, when counterweighted technology is used on three-pane configurations, each of the moving panes has zero weight.
Can sensors be installed so that the product stops if a person or pet walks under the door?
Yes, when automated vertical sash windows are installed they can be specified with a sensor to automatically pause the movement when movement is detected. These sliding window systems can also be specified with weather sensors, to automatically close the systems if rain, snow or strong wind is detected.
Can the tracks be driven over by a normal car?
Yes, the tracks are suitable for driving over and these vertically sliding window systems are perfect for creating contemporary car garages to showcase classic car collections.
What colours/finishes are available?
The slim aluminium profiles can be specified in a range of finishes, including any RAL colour for powder coating and specialist anodized finishes.
What colour/finish is used for the minimal windows vertical sash window at the IQ Glass showroom?
Our vertical sash window uses a new powder coated range, which has been developed to mimic the appearance of anodizing.
What are some of the potential uses for vertical sash windows?
Double height spaces can benefit hugely from vertical sash windows, creating light and bright spaces with very little visible framing. Some of the other uses include car garages, swimming pool areas, garden buildings and converted barns.
In recent years there has been a trend for modern Juliet balconies, using two-pane vertical sash windows where the top pane slides down to create a minimal balcony design, enhancing the ventilation on upper floors whilst maintaining uninterrupted paths of light and views.
