Hollow Glass ISO9001

Glazed doors and windows are the major approach for communications between indoor and outdoor spaces. Daylight, sight and decoration are the basic functions of glass while energy efficiency and environmental protection are further additional requirements to glazed doors and windows. For a well-closed space, the indoor and outdoor thermal exchange is mainly achieved through glass. The thermal exchange in large volume between indoor and outdoor spaces means that, in summer, unneeded heat is introduced into the rooms while in winter, the valuable indoor heat flows outward, which worsens the indoor living environment and leads to enormous increase in energy consumption by air conditioners and/or heaters. Insulating glass, especially that combined with solar reflective glass and/or Low-E glass, provides a sound solution. Insulating glass comprises two or more plies of glass that are separated with aluminum spacer fully filled with desiccant, and the sides are sealed with high-strength sealant. Annealed clear glass, tinted glass, solar reflective glass, Low-E glass, laminated glass, tempered glass, heat-strengthened glass and curved glass, etc. can be used to form insulating glass according to demands.

Specifications Maximum dimension (mm): 2500 x 5000 (except handmade) Minimum dimension(mm) : 300 x 300 Width of aluminum spacer (mm): 6, 9, 12, 16 Thickness(mm): various combinations of glasses between 3mm and 19mm thick

Quality Conforming to Chinese standard GB11944.

Features:

1. Optical Properties: the visible light transmittance of insulating glazing systems is normally in the range of 7-80% and the visible light reflectance is in the range of 10-48%;

2. Thermal Properties: the U-value is effectively lowered by insulating glazing and can be further reduced by filling of inert gases; Acoustical Insulation: insulating glazing can reduce noise by more than 30 dB;

3. Condensation: the dew point of insulating glazing systems is below -65 °C which guarantees no condensation formation under normal applications; Sealing: aluminum spacer is automatically curved and formed with the fewest joints and dual seals are applied, which ensures excellent sealing characteristics and long application life-time.
