Sealed glazing unit composed of two or more lites, reducing heat transfer and improving energy performance
Glazed doors and windows are the major approach for communication between indoor and outdoor spaces. Daylight, sight and decoration are the basic functions of glass, while energy efficiency and environmental protection are the further additional requirements for 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 volumes 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 an enormous increase in energy consumption by air conditioners and/or heaters. Insulating glass, especially that combined with high-performance low-E coating, provides a sound solution.
Insulating glass comprises two or more plies of glass that are separated with spacer fully filled with desiccant, and the sides are sealed with high-strength sealant. Anneal 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.
