中空玻璃是一种新型建筑材料。它不仅可用于建筑,还可用于冷冻冷藏、陈列橱、火车窗户等处。它是由两片(或两片以上)玻璃和间隔框构成的带有密闭的干燥空气夹层的组合件(其构造如图所示)。中空玻璃在国外已被广泛利用,而在我国还是刚刚开始。它同目前各类建筑普遍采用的普通双层玻璃窗相比,具有更好的隔热隔音和防结露性能。同时,普通双层玻璃窗需要两套窗框,而中空玻璃只需一套窗框,相比之下,中空玻璃窗还具有节约
Hollow glass is a new type of building material. It can be used not only for construction but also for refrigeration, showcases, train windows, etc. It is a combination of two or more pieces of glass and a spacer frame with a sealed dry air sandwich (as shown in the figure). Hollow glass has been widely used abroad, and it has just begun in China. Compared with common double-glazed windows commonly used in various types of buildings, it has better thermal insulation and anti-condensation performance. At the same time, ordinary double-glazed windows require two sets of window frames, while insulating glass requires only one set of window frames. In comparison, hollow glass windows also provide savings.
