Accessories - Air Tight Doors

No air tight door is completely air tight…however, each Diamond W. Air Tight door is made with a fireproof gasket, secure vertical locking rod and special air wash damper system that ensures additional comfort, efficiency and security.

As with all glass doors, the Air Tight door should not be closed when burning your fire. A closed door can cause excessive heat to build up on your glass doors and could cause the glass to break. Always burn your fire with your glass doors open.

The Diamond W. Air Tight door is only available for Rectangular or Arch Twin Doors. It cannot be used on any Bi-Fold door unit.
