    Q1: What is the difference between the 90 degree and 45 degree connecting?
    A: There are 90 degree and 45 degree corner connecting. 90 degree window is connected by
         screw, and we assemble the 45 degree window by corner brace. The 45 degree corner
         connecting window is new style, which is easy to overhaul.
    Q2: Do you know what is U-value?
    A: Yes, it simply means that every degree of temperature difference between a hotter air
         space and a colder air space, the heat energy will transfer per sq.m to the colder air space.
         For example, let say your house has a ceiling area of 100sqm, the difference in temp is
         30deg, and the amount of watts you pay for consume is 6000w. Then the U-value is
         6000w/100m * 30k=2w/(m *k).
    Q3: What type of fly screen you could supply?
    A: We have three styles of fly screen. One is roller style for casement window ,one is sliding
         style for sliding window and door, and the last one is folding style for casement door. 
         Besides, the fly screen is made of 3 different materials, namely nylon, steel and Kingkong net.
    Q4: PVC and aluminum, which is better?
    A: It’s hard to simply say one is better. Each one has its advantages. PVC is good at
         insulation and more economic. Aluminum is better in hardness and security.
    Q5: What kinds of packing do you have?
    A: There are three kinds of packing, such as bubble bag, bubble bag + wooden frame,bubble 
         bag + wooden case. If full container, we advise to use bubble bag, it can save more space 
         and hold more goods in the same container. Usually, the packing is bubble bag + wooden 
         frame. The best packing is bubble bag + wooden case, some bulk cargo and some developed 
         countries, such as USA, Australia and some countries in Europe,need wooden case packing, 
         because their special requirement and wooden case can protect the goods very well.
