Mainly used in cold areas with hot summer and cold winter. This type of glass makes you feel cool and comfortable inside the house in summer.

     It is made by special coating technology, adding several layers of ‘cooling film’on the glass surface. Sunlight heat will be blocked outside the window with only visible light coming in. The use of air conditioning could be reduced. Moreover, it has thermal insulation property with a low k value.

    Parameters of energy efficiency: total solar infrared heat transmittance gIR, heat transfer coefficient K, and visible light transmittance. The lower the gIR value, the less solar heat coming into the room, and the lower energy consumption of air conditioning; moderate visible light transmittance which reduces glare; K value varies in different heat engineering conditions.

     The insulating glass made by using this product is the best choice to achieve energy efficiency rate 90%, 75%, 65% in cold areas with hot summer and cold winter.
