Slim Sliding Doors and Structural Glazing for a Transparent Rear Addition
IQ Glass supplied a slim sliding door system across the main garden facing elevation, creating expansive openings with minimal framing and slim sightlines. The principal three track installation extends to almost 15 metres wide and 2600mm high, combining sliding and fixed panes to maximise the glazed area while allowing generous access to the exterior. Additional sliding and fixed glazed elements were integrated elsewhere in the elevation to complete the overall facade.
To reinforce the sense of openness, IQ Glass also designed and installed an Invisio® structural glass roof together with structural glazed vertical elements below. The roof spans approximately 14,400mm in width and is formed from four silicone jointed panes supported by low iron glass fins, allowing daylight to enter from above without the visual weight of conventional framing. A corresponding band of structural glazing beneath creates a continuous glazed relationship between the vertical and overhead elements.
Together, these glazing elements allowed the kitchen and dining spaces to open broadly onto the garden while preserving a calm and coherent architectural language. Solar glass was specified to the structural roof and glazed wall elements to help manage heat gain, ensuring that the extension delivered both visual transparency and practical performance. For a glass extension in Daventry, this combination of sliding doors and structural glazing demonstrates how large scale openings, overhead daylight and refined detailing can be resolved within a single design.
