Compared with ordinary double-glazed windows Crown hollow glass is better insulation, sound insulation and energy-saving building materials. By the two float glass through effective sealant and insulating glass spacer material, the middle layer of the thermal conductivity of about 0.026W / m · K air layer, which greatly improved the noise insulation properties of glass.
◆energy-saving effect is remarkable: shading coefficient of 0.22-0.49, heat transfer coefficient 1.4-2.8W / m · K, are better than ordinary glass.
◆improve the indoor environment: interception by the solar energy hitting the chamber, sunscreen, anti-afterglow dazzling.
◆rich colors and artistic: high performance insulating glass a variety of colors can be selected according to need
