The oversized, vertical sliding window system adjacent to the front of reception is the perfect statement of expertise upon arrival at the IQ showroom. Standing at 6.5m tall and 3.5m wide, the middle and lower glass units seem to defy gravity as they slide effortlessly upwards to slot in with the middle pane, via an integrated motorized system.

The counterweighted sliding sash windows offer ultra slim frames of just 21mm horizontally, making the system the perfect combination of smooth and easy openings and minimalist detailing.  The oversized window system is complete with a flush threshold that can be driven over, for a seamless transition between inside and out.  

With each sliding pane having the ability to achieve dimensions of up to 29m2, the widths of glass openings achieved by IQ are hugely impressive and give the impression of moveable, minimally framed glass walls to visitors, whilst also creating an unparalleled spatial experience. As with all of the products on show at the showroom, the architectural resolution focuses on bringing external light into internal spaces, and the slim horizontal sightlines of the aluminium profiles allow for a double height elevation of glass with maximum transparency.  

In terms of the performance of this oversized system, the framing sizes, depths, performances, and glass rebates for these vertical sliders are inherited from the base minimalist slider. Moreover, there are numerous different predetermined configurations for the vertical sash system - it is available as standard in a double sliding sash as shown in the showroom, or you can also specify a fixed + sliding + fixed configuration where the middle pane opens. Furthermore, three pane vertical sliders that span multiple floors are possible as well as minimal sliding units that create Juliet balcony structures.
