PPG Industries (NYSE:PPG)已经引入了双涂层技术,该技术有助于双窗格绝缘玻璃单元(IGU)实现R-5绝缘性能。
双涂层技术包括一个3毫米窗格的Solarban(R)70xl玻璃,位于IgU的第二个(#2)表面和一个3毫米的3毫米窗格(r)500玻璃(#4)表面,由½英寸充满氩气的空间隔开。该配置产生了0.20的冬季U-Value,提供的绝缘性能比市场上任何竞争的双窗格IgU更好或等于。
PPG经理技术服务,Performance Glazings表示,R-5 Windows在联邦立法中强调了U-Value为0.20或更少的U-Value,并在建筑法规中采用以提高住宅建筑的能源效率。
他说:“窗户和门制造商正在寻找玻璃解决方案,结合更节能的窗扇和框架技术,可以帮助其产品实现R-5绝缘性能。”“我们的玻璃解决方案使他们能够做到这一点。”
The dual-coat technology is significant because it enables window and door manufacturers to make better-insulating products without multiple air spaces and panes of glass. Multi-cavity IGUs can complicate the manufacturing process for window and door makers and add to the cost that builders, remodelers and homeowners pay for windows.
PPG's dual-coat, double-pane IGU has visible light transmittance (VLT) of 60 percent and a solar heat gain coefficient (SHGC) of 0.26.
