Insulating Glass Unit

Insulating glass consists of assembling two or more individual lites separated by a dehydrated and hermetically sealed air space. These sealed units contribute to improved building energy performance.

By changing the number, type and thickness of the components used, we can create a wide range of glazings that meet specific requirements such as:

  • Countering solar heat gain
  • Preventing heat loss in winter
  • Resisting wind and snow loads
  • Improving natural light quality, while enhancing the appearance of a building

CHARACTERISTICS

  • Measures the standard thickness of insulated glass units for ICI (industrial, commercial and institutional) buildings—25 mm—with two lites of 6 mm glass and an air space of 13 mm. Other configurations are available to meet certain specific requirements.
  • Available in large formats

PRODUCTION CAPACITY

*  Maximum insulated glass unit dimensions are determined by a number of factors, such as their thickness, weight, ratio of width/height, application and loads (ex. wind and snow). Maximum, achievable, dimensions do not imply that sealed units manufactured to these dimensions will meet all laws, rules, regulations and other requirements. It is up to the user to ensure that the products they order are suitable for their intended use.
