All criteria for selection noted in previous comments are important with one very relevant component missing, that being the support and training provided by the manufacturer throughout the entire process. This would include the selection and submittal process to installation to issuing of the manufacturer's warranty. A manufacturer with an ethical technical staff who will take the time to objectively go through the selection process with you is invaluable. This would be especially true for specifiers early in the design process as well as contractors who may be limited in availability of specified products, as it's never too late to get the right product approved.
