1、在光线能够穿透的情况下，室外各室内传热分为两部分，一个是热交换，二是阳光中的红外线。玻璃制造商表示解决方案是low-E中空玻璃，low-E的银膜可以大幅度反射红外线，中空部分阻隔热交换，关于以上两点，展开可以很长，此处只讲原理。
1, in the case of light penetration, indoor heat transfer is divided into two parts, one is heat exchange, and the two is infrared in the sun. The glass manufacturer said the ultimate solution is low-E hollow glass. The silver film of low-E can reflect the infrared greatly, and the hollow part obstruct the heat exchange. The above two points can be extended for a long time. Here we only talk about the principle.
具体到水果店，他家肯定是low-E钢化夹胶玻璃，可以理解为特种胶粘合两片或多片钢化过的low-E玻璃。
Specific to the fruit shop, he is certainly low-E tempered glass, can understand the bonding of two or more pieces of steel for special glue low-E glass.
为什么这样选择，我的理解是：low-E反射红外线（不是紫外线，不是紫外线，不是紫外线）；钢化增加玻璃强度和性（考虑到玻璃破碎时的情况）；夹胶增强整体强度（多层钢化夹胶达到一定的厚度和强度就是防弹玻璃）；为什么不用中空和幕墙组件，还是逼格太low，太多附件了（不用中空的结果就是，它仍然很热，因为热交换通道没有阻断）。
Why do you choose, my understanding is: low-E reflection infrared (not ultraviolet, not ultraviolet, not ultraviolet); increase the strength and safety of toughened glass (taking into account the broken glass case); the overall strength enhancement (multilayer laminated toughened laminated reaches a certain thickness and strength is bulletproof glass); why not hollow and curtain wall components, or forced too low, too much attachment (not hollow result is that it is still very hot, because of the heat exchange channel without blocking).
另外：漏了一点，据Jiahao Lu所查资料，水果店用的是半钢，不是全钢，这跟汽车前挡风玻璃是一样的。
In addition: a little missed, according to the data found by Jiahao Lu, the fruit store is using semi steel, not all steel, which is the same as the front windshield of the car.
2、超白玻璃和low-E并非不能相容
2. Ultra white glass and low-E are not incompatible
制造超白玻璃的必要条件是石英砂含铁量足够低（Fe2O3≤0.008%）（此处多谢
Necessary conditions for manufacturing of ultra white glass is quartz sand iron content is low enough (Fe2O3 = 0.008%) (here thank you

批评指正！），超白玻璃的主要用途是太阳能板，如果含铁量高，玻璃会呈现绿色，而且透光率会下降。
Criticism and correction!) The main use of ultra white glass is solar panels. If the amount of iron is high, the glass will be green and the transmittance will fall.
目前国内做low-E大板的都宣称使用超白玻璃，其实达不到，但已经比传统浮法原片要好很多。从原理上说，low-E和low-iron是不冲突的：
At present, the low-E board in China claims to use ultra white glass, which is not true, but it is much better than the traditional floatation. In principle, low-E and low-iron are not conflicting:
low-E，Low emissivity，低辐射玻璃，是用镀膜材料对红外线辐射的强反射为诉求（可以参考热水瓶胆，救生毯）的功能性玻璃，分为在线low-E和离线low-E，分别是镀膜材料在玻璃内部和在外表面。这和超白玻璃的低铁并不冲突。
Low-E, Low emissivity, Low-E glass, is a strong reflection of infrared radiation with the coating material for the demands (can refer to hot water flask, rescue blanket) functional glass, divided into low-E online and offline low-E, respectively in the coating materials of internal and external surface of the glass. This ultra white glass low iron does not conflict.
3、关于屏幕反光的问题，改变玻璃并不能改变这一点儿，so be it!
3, on the screen reflection problem, change the glass and not change this, so be it!
又或者毛玻璃能有小小的改观？
Or can there be a little change in the wool glass?
4、水果店的玻璃为什么贵
4. Why the glass in the fruit shop is expensive
刚才讲了这么多技术方面的问题，无论从哪种工艺来讲，并不能使它的高逼格玻璃达到天价水平，能使它达到这么高价格的因素只有一个，那就是尺寸、尺寸、尺寸！
Just now, I talked about so many technical problems. No matter what kind of technology it is, it can't make its high price glass reach the high price level. The only factor that can bring it to such a high price is size, size and size.
如果玻璃尺寸达到一定的尺寸，那么浮法原片出流水线切割的时候破损率会非常高。。。
If the glass size reaches a certain size, the breakage rate will be very high when the floatation line is cut through the pipeline.
离线low-E镀膜生产线的真空腔室必须要大于玻璃的尺寸，造价非常高，可以轻松突破billion
The vacuum chamber of the off-line low-E coating line must be larger than the glass size, and the cost is very high and can easily break through the billion
夹胶高压釜必须大于玻璃的尺寸，造价，my dear。。。
The laminated glass autoclave must be greater than the size, cost, my dear...
钢化炉尺寸。。。
The size of the tempering furnace.
运输，nightmare
Transport, nightmare
比较后，这种尺寸的玻璃肯定是定制，成本再上升
Finally, the size of the glass must be customized, and the cost will rise again.
