As with all doors to be included in the project, all windows should be listed on the drawings in a window schedule. If none is included, it may be well worth the time to create one. The schedule should contain the opening number, window type, window size, and glass type.
Different openings require different types of glass. The three most common types are:
The insulation or"u" value is a strong consideration, along with solar heat gain.
Exterior windows - Most exterior windows are glazed with insulating glass.
Entrance doors and window walls - where the glass is less than 18" from the floor, are generally glazed with tempered glass.
Interior windows - Interior windows and some residential windows are glazed with float glass.
Coastal areas - Coastal communities are starting to require the use of impact-resistant glass.
