Glass in construction. Gurrent situation and the R+D orientation

Abstract

Glass, with its different forms and compositions, constitutes one of the most widely used materials in construction. It performs various functions: Aesthetics, Comfort, Security. Although it is an old material, thanks to the effort of the R+D it has undergone significant evolution in the recent years. New properties and functions have been developed through modification of its composition, surface treatment and association with other products. This article gathers a large number of new products and the procedure for their obtaining, pointing out their application and functionality in construction. There is a certain emphasis on some surface treatments (mainly thin layers) of flat glass, due to its special implantation in modern construction. There is also a description of compound products and their more functional uses. Glasses with properties varying according to the user's wish are the object of various current developments and will surely have an ample application in the near future.
