Are glass walls expensive?

Glass walls are generally more expensive than walls made of traditional materials like bricks or drywall. However, the total cost of installation becomes lower for glass as the building gets taller. While the cost of the walls themselves remain constant, glass walls are much easier to lift than individual bricks.
