Nakajima Glass Company, Inc.
Insulating Glass Unit
Insulating glass unit is high thermal insulation glass with air sealed between two sheets of glass. Due to its high thermal insulation effect, you won't feel the outdoor heat or cold even when standing by the window, allowing you to effectively utilize every corner of the room. It is also very effective in preventing condensation and significantly suppresses unpleasant condensation in winter.

Key Features

  • High thermal insulation - less affected by outdoor conditions even near windows
  • Saves on heating and cooling costs
  • Less likely to cause condensation

Manufacturing Method

A spacer containing desiccant is attached a few centimeters inside the outer periphery of the first sheet of glass. The second sheet of glass is pressed onto the spacer. The outer periphery of the spacer is filled with sealing material and completely sealed to complete.
