ABSTRACT
Selection of glass type involves consideration of a range of factors and combination of a number of processes to achieve the required set of properties. In some cases, the design will be constrained by the limits of one or more processing steps, particularly when it comes to panel size and the inner and outer panes of insulating units are commonly different types. Only after the glass type has been selected can a suitable thickness be calculated. There are no mandatory requirements for deflection limits on window glass specified in codes of practice commonly used in the United Kingdom, United States, and Europe. Most glass design codes allude to the need to limit deflection but avoid direct specification. The strength and stiffness of laminated glass depends on the extent to which the interlayer couples the two sheets of glass in shear. The use of glass as a floor introduces the need for slip resistance and increases the level of robustness required.
