Insulating glass basics

1. Insulating Glass - Aluminum Thermal Method

The aluminum thermal method is a process that uses aluminum as a reactive metal to produce heat through an exothermic reaction. When exposed to air, aluminum forms a dense oxide layer on its surface, which prevents further oxidation. However, at high temperatures, aluminum can react with oxygen and release a significant amount of heat. This property allows aluminum to act as a reducing agent, replacing other metals from their oxides in the aluminothermic process. This method is commonly used in the production of insulating glass to enhance structural integrity and thermal performance.

2. Insulating Glass - Desiccant

The desiccant used in insulating glass plays a crucial role in maintaining the clarity and efficiency of the unit. It absorbs any residual moisture or gases trapped between the two panes of glass, preventing condensation and fogging, especially under low-temperature conditions. By keeping the space between the panes dry, the desiccant ensures that the glass remains clear and transparent, while also improving the insulating properties of the glass. This helps extend the lifespan of the insulating glass and maintain its energy efficiency over time.

3. Insulating Glass - Sealant

Sealants are essential components in insulating glass units, providing both functional and protective benefits. A good sealant should have the following characteristics:

  • Ability to prevent gas leakage
  • Resistance to water vapor permeation
  • Protection against ultraviolet radiation
  • Ability to prevent water seepage
  • Strong adhesion to maintain the structural integrity of the glass unit

These properties ensure that the insulating glass remains effective for a long period, maintaining thermal and acoustic insulation while protecting against environmental factors.
