Glass whiteboards are made of tempered glass that is up to ten times durable than regular glass. The glass boards are easy to clean, stain-resistant, and incredibly durable, and they hang beautifully on any wall. And because they are made of glass, they blend seamlessly into any interior and can be used as a design element in a room. Glass whiteboards can be either magnetic or non-magnetic. Magnetic glass boards are generally back-painted tempered glass laminated to steel.
