The glass panel may be formed from plural layers of laminated glass. A sealing layer is disposed between the top surface and the sacrificial glass layer to define a chamber therebetween. The glass assembly further includes a valve providing fluid communication between the chamber and the environment to facilitate evacuating fluid from the chamber.
