一、节能、隔音

的导热系数为0.325w/m.k，大约是粘土瓦的1/3，10mm厚水泥瓦的1/5，0.5mm厚彩钢瓦的1/2000。在不考虑加保温层的情况下，瓦的保温性能仍能达到最佳。通过音位测定实验表明，在遭受暴雨、冰雹、大风等外界影响时，瓦都能很好的吸收噪音。

二、抗冲击耐低温效果好

1公斤重的钢球自1.5米高度自由落在瓦面上不产生裂纹。经过10个冷冻循环，瓦无空鼓、气泡、剥离、裂纹现象。

三、色彩持久

该即使长期暴露于紫外线、湿气、热、寒和冲击下，仍能保持其颜色的稳定性。通过国家化学建筑材料测试中心12000小时的人工老化测试，检测结果△E=2.86。

四、卓越的抗荷载

通过国家化学建筑材料及构件质量监督站检测，在支撑间隔750mm情况下，加重150kg，产品没有被破坏。

五、卓越的自防水性能

所选用的高耐候性树脂本身致密且不吸水，不存在微孔渗水的问题。的单张面积大，屋面接缝少，搭接处结合严密，可以省去防水层。

六、质量轻

每平方米重6.1kg是一种轻质材料。无需加装过多钢结构，对墙体、地基承重要求小。

七、自清洁

该产品本身不宜吸附灰尘，一经雨水冲刷便洁净如新，不会出现积垢后被冲刷的斑斑驳驳的现象。

八、优异的耐腐蚀性能

该产品可以长期抵御酸、碱、盐等各种化学物质腐蚀，不会被雨雪侵蚀导致性能下降。

九、耐火性强

该产品主体树脂属难燃产品，经国家防火权威部门检测防火性能达到B1级。

十、体积稳定

的膨胀系数为4.93×10-5(1/℃)，并在几何形状设计上具有双向拉伸性能，即使温度变化很大，瓦的伸缩也能被自身消化，确保瓦的几何尺寸稳定。

十一、绝缘

该产品的另一个技术特性是不导电，遇到意外放电也会完好无损。

十二、安装简单

该产品只需用螺钉固定在钢檀上，再辅以主脊，斜脊等配件，便可经久耐用，使用寿命长达35年以上。

British Airways is still cancelling flights in the aftermath of a three-day strike by cabin crew.

The airlines website shows it has cancelled nearly 200, or more than 19%, of flights that had been scheduled up to midnight on Tuesday.

BA is reviewing its schedule for a further strike between 27 and 30 March.

No further talks to resolve the dispute are planned ahead of the next walkout, but unions have challenged BA chief Willie Walsh to return to negotiations.

BA says the majority of services in the next four days will operate normally.

But on Tuesday, in the immediate aftermath of the strike, its services at a number of major British airports continued to be disrupted.

More cancellations

At London Heathrow, its biggest UK hub, it has cancelled 14% of outgoing flights and more than a third (34.2%) of arrivals.

At Manchester, more a a fifth of all services have been cancelled.

At Newcastle, the figure is even higher, at 58.3%.

Aberdeen, with more than 28% of BA flights cancelled, and Glasgow, at 18.2%, are also among the worst-hit.

Gatwick, London City, Birmingham, Belfast and Inverness are unaffected.

In a statement issued to the London Stock Exchange about its operations over the weekend, BA said it estimated the three-day strike had cost the company ?7m a day.

But the airline said the industrial action was unlikely to have much impact on its full-year earnings figure.

It suffered a loss before tax of ?342m for the nine months to the end of December 2009 and says it needs to cut costs in order to survive.

Correct positions

According to the companys website, about a third of flights to and from the UKs main airports on Monday were cancelled.
