Vertical Sliding Sash Windows

Vertical sliding sash windows, sometimes known as guillotine windows, are innovative glazing solutions that give projects a ‘wow’ factor. 

Oversized Vertical Sash Windows

Our sliding sash windows are designed to offer a bespoke opening, pairing minimal design with smooth action openings.   

The large, insulated units can be used to create vertically sliding glass walls, introducing paths of natural light into the property thanks to the high glass to frame ratio.

Able to be specified in two or three-pane configurations and as double-height glazing elevations, this unique glazing solution is sure to enhance the design of any project.

Double Height Sash Window

This unique glazing solution is often specified as a double-height window. This means that whether the window is designed as a two or three pane system, as the bottom pane lifts up over the other pane it leaves an open aperture that can be used as an access point.

IQ have designed and installed many of these systems around the world, including a 6.5m tall vertical sliding sash window at our showroom in the UK. 

Motorization

When specifying large glazing solutions where pane can weigh upwards of 500kg, we may recommend incorporating a motor to allow the system to be operated automatically with an easy control option.

Control options for automated sash windows including a wall switch, remote or it can be integrated with smart home automation and BMS systems.
