Many of today's architects love designing prestigious buildings with glass exteriors: opulent skyscrapers and buildings for a variety of activities, many of which are being built using colourful coated glass. As well as being visually appealing, using glass for construction significantly reduces building costs and shortens completion time. The design can create an air of opulence unmatched by other building materials. New silicone based elastometric coatings will allow spandrel glass to be screenprinted rather than roll-coated, thus reducing the need for additional processing equipment. Typical glass sizes are growing, with sheets measuring over 3x6m being used frequently.
