The primary means of meeting thermal performance for fenestration products is the frame and glass selection. In addition to the proper selection of frame and glass, the integration of sun control devices into a project could add significant benefits. Sun control devices can consist of exterior attachments (i.e. sun shades and shutters), interior attachments (i.e. light shelves and blinds), integrated devices (blinds) and photovoltaic devices.

Proper use of these devices can save money and/or improve occupant satisfaction and productivity. For details on these devices, visit the Aluminum Solar Control and Daylighting web page.
