Low-E Glass

Sisecam Low-E Glass is Sisecam Flat Glass’ heat control glass. Sisecam Low-E Glass is preferred in residential, small/medium sized commercial buildings.

Sisecam Low-E Glass reduces heat loss from windows by 77% compared to single glazing, 50% compared to ordinary Insulating Glazing Unit (IGU) and provides savings from heating expenses.

Advantages

  • High surface resistance
  • Reduces heat loss by 50% compared to ordinary insulating glass units
  • Provides heat control and energy efficiency
  • Decreases heating expenses
  • Does not compromise on natural daylight and transparency
  • Ensures maximum benefit from solar heat
  • Eliminates cold spots close to window and condensation on glass surface
  • Protects against UV radiation over 68%, reducing fading and aging effects
