Questions and Answers

What is the purpose of using argon or krypton in the airspace between the two panes of glass in an IGU?

  • To improve the visual clarity of the IGU
  • To provide further insulation due to their density and reduced heat conduction (correct)
  • To enhance the soundproofing capabilities of the IGU
  • To reduce the weight of the IGU

What is the function of the Intercept® Spacer System in an IGU?

  • Increasing the flexibility of the IGU
  • Enhancing the aesthetic appeal of the IGU
  • Improving the sound insulation of the IGU
  • Creating an effective thermal barrier at the edge to reduce conducted heat loss (correct)

What does a low-e glass coating do in an IGU?

  • Enhances the UV protection of the IGU
  • Increases the weight of the IGU
  • Improves the window's overall u-value by reducing heat transmission (correct)
  • Improves the scratch resistance of the IGU
