Modern Architectural Glazing

Are you looking for an efficient and specialist glazing company, able to provide your project with modern architectural glazing? Whether you are seeking a thermally broken steel window or an ultra-slim sliding glass door, IQ® Glass has been the UK’s leaders in the field of architectural glazing for over 20 years.

IQ® Glass supplies and installs some of the most pioneering architectural glass technology available today, including frameless structural glass assemblies such as frameless glass balustrades, frameless rooflights, structural glass roofs and glass floors, curved glass, and glass extensions. Our extensive range of contemporary framing solutions includes Frameless glass windows, large sliding doors, aluminium casement windows and doors, and specialist flush glazed systems. Mixing technical glass solutions such as heated glass, privacy glass, and specialised glass coatings allow these minimally framed glazing systems to be as functional as possible.
