Linc is a database of Glass Types which provides a range of properties that may be assigned to glazed elements in the Revit model. The database may be filtered using the following categories: U-Value, SHGC and VLT. This will then provide a shortlist of suitable glass types from which you may choose. These may be substituted for those that are available in Revit. Sample generic Glass Types and manufacturer’s products are listed with a wide range of properties.
