Transparent Coating

Choose Transparent Glass Coating for Glass Surfaces

Heat insulating coatings for glass windows aim to improve your home’s energy efficiency by reducing heat transfer through the windows. Ideally, these coatings achieve this goal without significantly impacting visibility. Here’s a breakdown of the different types of heat insulating coatings that prioritize maintaining a clear view:

1. Low-emissivity (Low-E) Coatings:

  • Function: These microscopically thin metallic layers reflect infrared (IR) radiation, a major component of solar heat, while allowing most visible light to pass through.
  • Benefits: They offer good heat insulation in summer (keeping interiors cooler) and winter (reducing heat loss). They also typically have minimal impact on visible light transmission, maintaining a clear view.
  • Variations: There are different Low-E coatings with varying degrees of solar heat rejection and visible light transmission. Lower emissivity ratings indicate better heat blocking performance.

2. Spectrally Selective Coatings:

  • Function: A type of Low-E coating specifically engineered to be highly transparent to visible light while reflecting infrared radiation.
  • Benefits: These coatings offer the best of both worlds: excellent heat control and minimal impact on visibility, making them ideal for maintaining a clear view while improving energy efficiency.

3. Advanced Nano-particle Coatings:

  • Function: These emerging technologies utilize microscopic nanoparticles suspended in a liquid solution to create a heat-reflective layer on the window.
  • Benefits: Some manufacturers claim these coatings offer high heat insulation with good transparency. However, this technology is still relatively new, and independent verification of claims might be limited.
