现在的铝合金门窗的玻璃配置大多是双层中空钢化玻璃，隔音效果已经十分优异。现在有很多消费者追求更高的配置，听说现在有了三层中空玻璃，就想问三层中空玻璃会比双层中空玻璃的好吗？
▌三层中空玻璃比双层中空玻璃隔音效果好多少？
三层玻璃的厚度一般是5+5+5+0.5+0.5=16MM左右。为什么要三层呢，型材间是不可能没有一点漏气的缝隙的，单窗三层玻璃隔音隔热效果的增加不如单玻璃窗+中空玻璃窗，理想的增加隔音隔热的做法是，外面一层单层玻璃窗，里面再做一层玻璃窗用中空玻璃，除夕子夜放炮最吵的时候，外面的声音也比室内闹钟的滴答声轻，中空玻璃比较怕潮气起雾，单玻窗挡外面的水气，双玻窗隔室内的热量，三玻双窗隔绝噪音，这是最理想布局了。
▌三层中空玻璃窗配哪种规格的铝型材，三层中空玻璃中空层有多少毫米厚？
做三玻窗，型材最好选着65以上型材这样才能保证三玻两腔空间大于10mm中空玻璃空间距离越大，保温隔音性就越好，由于中空玻璃内部存在着可以吸附水分子的干燥剂，气体是干燥的，在温度降低时，中空玻璃的内部也不会产生凝露的现象，同时，在中空玻璃的外表面结露点也会升高。
如当室外风速为5m/s，室内温度20℃，相对湿度为60％时，5mm玻璃在室外温度为8℃时开始结露，而16mm(5+6+5)中空玻璃在同样条件下，室外温度为-2℃时才上结露，27mm(5+6+5+6+5)三层中空玻璃在室外温度为-11℃时才开始结露。
由于中空玻璃的隔热性能较好，玻璃两侧的温度差较大，还可以降低冷辐射的作用;当室外温度为-10℃时，室内单层玻璃窗前的温度为-2℃而中空玻璃窗前的温度是13℃;在相同的房屋结构中，当室外温度为-8℃，室内温度为20℃时，3mm普通单层玻璃冷辐射区域占室内空间的67.4％，而采用双层中空玻璃(3+6+3)则为13.4％。使用中空玻璃，可以提高玻璃的安全性能，在使用相同厚度的原片玻璃的情况下，中空玻璃的抗风压强度是普通单片玻璃的1.5倍。
▌三层中空玻璃中空层有多少毫米厚与普通两层中空玻璃比较一样吗？
一、中空玻璃中空层厚度一般为6mm～20mm;在特殊情况下，也有大于20mm的情况，但极为少见;如果中空层的厚度小于6mm，则其隔音量与相同厚度的单片玻璃相差无几，因此，中空层最小厚度为6mm。
二、中空玻璃的表示方法为三段表示法，比如：“5+9A+5”，两边的“5”表示原片玻璃的厚度为5mm;“A”是中文空气一词的英文(Air)的缩写，“9A”的意思是中间玻璃间隔厚度为9mm。我们在平常最常见到的，以9A和12A两种规格居多。
三、原片玻璃的规格通常为：3mm、4mm、5mm、6mm、10mm和12mm六种，对于相同厚度的原片玻璃，中间玻璃间隔越大，允许的最大面积也越大。
四、中空玻璃是由两片或多片玻璃以有效支撑均匀隔开并周边粘接密封，使玻璃层间形成有干燥气体空间，从而达到保温效果，是一种节能型玻璃，比如“5+9A+5”的普通中空玻璃，大体相当于100mm厚普通混凝土的保温效果。
五、除了隔热保温功能外，中空玻璃还具有光学性能良好、防结露及良好的隔声功能，因此，常用于对保温隔热、隔声功能要求较高的建筑物，如宾馆、住宅、医院、商场、写字楼等，也广泛用于车船等交通工具。
▌三层中空玻璃的优势，与双层中空玻璃对比哪个实用？
三玻说白了就是双层中空，隔温隔音效果要比普通中空效果好得多。一般在东北三省或高寒地区用得比较多，隔温隔音效果比普通中空效果好得多。要说实用的话那肯定是双层玻璃实用便宜。
On September 6, 2018, the China Glass Composite Index rose 1.09 points, 1.36 points, 1,294.22 points, 1.09 points, 1,222.72 points, and China Glass Confidence Index 1080.22 points, 0.03 points, respectively. Today, the overall trend of glass spot market is stable, the main production enterprises to increase the warehouse and withdrawal funds, regional market prices have risen. In the early period, the price of northern China, especially Shahe, rose too fast, which weakened the competitive advantage of local prices in the surrounding market, and some production lines stopped production unexpectedly, which slowed down the speed of TRADERS'purchasing. And the recent outbound South market is still available, some manufacturers began to quote slightly follow up, the market reaction is normal.
Looking back to August, the spot market began to rise sharply, and significantly higher than the same period in history. After the coordination meeting held by manufacturers in various regions, they successively formulated the price increase plan for peak season, preheated the market ahead of schedule. Then, with the environmental protection of Shahe area, they shut down three production lines successively, and then there will be new measures to limit production, market trust. Immediately after that, the spot price of glass in some parts of the country was close to the high point of the year.
In contrast, the real estate market is the main demand side of glass. From the current point of view, the weakening of the real estate market may lead to a long-term downturn in glass demand, the terminal demand has not increased significantly after the peak season.
The weakening of the real estate market is mainly due to the tight capital of housing enterprises, housing sales have fallen since August, especially in the third and fourth-tier cities, housing sales have further fallen, resulting in a tight capital situation intensified housing enterprises, the completion of a rapid rebound is more difficult. After entering the heating season, the northern region will start a new round of environmental inspection, will inevitably affect the construction site, so glass demand in the heating season before rush to stimulate the release of phases, may continue to weaken.
To sum up, Shahe and other regional manufacturers should mainly increase the funds from the warehouse and withdrawal, the price adjustment should not be too large, the early price rise too fast, it needs a certain period of digestion process.
