The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect parallel surfaces.

The 1 inch insulation glass is typically made up of two 1/4-inch lites of glass with a 1 ⁄ 2 inch (13 mm) airspace. The air inside is usually atmospheric air, but some inert gases, such as argon or krypton, may be used in order to offer better thermal transmittance values. In Europe, triple-pane insulating glass infill is now common.
