In other words, if you buy back its true hollow glass is "empty", Laiwu within laminated insulating glass, it will undoubtedly explain the thermal insulation at cold performance or, at best, double glazing, thermal insulation effectiveness of the inevitable difference, scientific testing proved qualified hollow glass, can generally limit window heat transfer coefficient k value of 3.5 down to 2.8 from the original, the heat transfer performance degradation can make the room heat is not easily lost. Market counterfeit hollow glass, hollow glass processing, usually just the two pieces of glass held together simply, hollow glass offer, its thermal performance is undoubtedly very poor. Super Spacer Insulating glazing insulating glass, can seal a sufficient depth of hot melt butyl rubber on the outside of Super Spacer to guarantee insulating glass sealing system has sufficient resistance to water vapor permeability. Hollow glass curtain wall, must marshal sufficient depth of the third layer structure of plastic on the outside of the hot melt butyl rubber, in order to ensure insulating glass has sufficient structural strength and service life. Insulating glass manufacturers, Jinan Yaohui glass, hollow glass provided by Jinan Laiwu Glass Co., Ltd. Yaohui. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) Shandong Jinan, architectural glass leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
