The Project references app is a useful tool for professionals in the construction industry and a valuable source of information for those interested in modern architecture. A new, attractive design, intuitive search engine, great pictures and the option of sharing project information via social media are the main features of the app presenting the most interesting architectural projects using Pilkington glass. Users of the app can search projects by location, type of building, benefit-led category, type of glass, or by simply typing text into search. The app can be used to visit projects located in the users’ location and gain a better feel of how the glass products look in real applications. Local language searchable databases are available for a number of countries in addition to the global database that includes projects from all over the world with descriptions available in English.
