Because of the massive sizes that these guillotine windows can achieve the sliding glass sashes can be used as a full façade on double height spaces.

The high standard of manufacture ensures that your 'IQ Glass' package is a quality solution. High and varying levels of performance in thermal insulation, solar gain and transparency are available and the IQ Glass team are able to assist in specifying your 'window and door package' so that the performance requirements of your project are met cost effectively.

The sliding sash window can be designed with automated motors for electrical opening or counter weighted for a smooth manual opening action. The size of the moving elements of sliding glass will determine the size of clearance required to the side of the Guillotine Window installation to allow for these moving mechanics.

To maintain the slim 21mm horizontal transoms IQ integrate a minimal two point locking system operated via a thrust lever handle. When the small handle is turned steel shot bolts fit from within the horizontal 21mm transom frame into the opening sides, locking the windows closed and into the building structure.
