并周邊粘結密封，使玻璃層間構成單調氣體空間的制品。中空玻璃的曠地空閑開始是單調的空氣，現在多用導熱率比空氣低的其他氣體，如惰性氣體等。中空玻璃又稱隔熱玻璃,由兩片或多片玻璃以有效支撐均勻離隔。
And the peripheral bonding seal makes the glass layer form a monotonic gas space product. The open space of the hollow glass was originally monotonous air, but now other gases, such as inert gases, with lower heat conductivity than air, are commonly used. Insulating glass, also known as insulating glass, is evenly separated by two or more pieces of glass.
抗風壓成為幕墻的首要指標。中空玻璃的抗風壓強度是單片玻璃的15倍玻璃不易自爆：中空玻璃出產方法為粘結法，抗風壓強度前進：幕墻首要接受風荷載。為冷加工，玻璃原片內應力不改動，四周以彈性資料密封，玻璃不易自爆。
Wind resistance has become the primary indicator of curtain wall. The wind pressure strength of hollow glass is 15 times that of monolithic glass, which is not easy to spontaneous explosion. For cold working, the stress in the original glass sheet is unchanged, and the surrounding is sealed with elastic material. The glass is not easy to explode.
而鍍膜中空玻璃的金屬膜面處在單調的密封空氣中永不墜落。鍍膜玻璃膜層不會墜落：鍍膜玻璃的金屬膜面不可暫時露出于空氣中。
The metal film surface of the coated hollow glass is kept in a monotonous sealed air and will never fall. The film of coated glass will not fall: the metal surface of coated glass shall not be temporarily exposed to the air.

中空玻璃具有隔音隔熱保暖的作用而被廣泛運用在家裝中，可是市面上中空玻璃的質量良莠不齊，
Hollow glass has the function of sound insulation and heat preservation and is widely used in home decoration. However, the quality of hollow glass in the market is uneven.
1.看是否有鋁隔條
1. see if there is aluminum partition.
鋁隔條上還有許多透氣孔，里面放上單調劑，可以吸收氣體中的水分，避免玻璃門窗受熱后出現“霧蒙蒙”的現象，而假“中空”玻璃沒有這些設備。
There are also many air holes on the aluminum separator, which are filled with monotonic agent to absorb moisture in the gas, to avoid the phenomenon of "foggy" after heating the glass doors and windows, and the fake "hollow" glass does not have these equipment.
2.看外觀
2. look at the appearance
優良的型材看上去外表潤滑細膩、平整潔凈、色彩均勻、沒有裂縫、氣泡;焊接處沒有斷裂開焊的現象;硬度厚度滿足，用榔頭敲擊型材外表不出現分裂。而殘次的型材色彩不均勻，有氣泡雜質，用榔頭敲擊會出現分裂，甚至用手捏都會變形。消費者可以從旁邊面查詢玻璃，玻璃平整、沒有色差，透過玻璃看物品，物品沒有變形，就是合格的產品。
High-quality profiles appear to be lubricated exquisite, smooth and clean, uniform color, no cracks, bubbles; welded joints do not break open welding phenomenon; hardness and thickness meet, with hammers knocking profiles with no splitting. And the residual profile color is not uniform, there are bubble impurities, with hammer knock will split, and even with hand pinch will be deformed. Consumers can check the glass from the side, the glass is flat, no color difference, through the glass to see things, no deformation, is qualified products.
