Thermal Control
In residences, small/medium sized buildings, and cold climate regions, it is necessary to use double or triple insulating glasses containing Low-E coating to prevent internal heat escaping.
Advantages of using this type of insulating glass;
• Reduces heat losses by 50% compared to standart insulating glass.
• Provides thermal insulation and energy saving.
• Reduces fuel costs.
• Does not compromise on transparency and natural daylight.
• Provides maximum benefit from solar heat.
• It prevents window fronts from being cold in winter and delays condensation on the glass surface.
• Prevents the colors of furniture from fading blocking the passage of ultraviolet (UV) rays by 76%.
