This restaurant design includes (4) standard size Ready Access 600 Series windows with ¾" dual pane insulated low-e glazing (Solarban 70XL) for energy efficiency and staff comfort. All windows "self close" per health code to protect the operation from insects, car fumes and outside temperature. The self-closing operating system is manual open/self-close (SC) which is gravity fed – no power required. This operating system is extremely durable and easy to maintain. All windows operate on an overhead track to keep the service area track free for easier service and cleaning.
