Q1: Are there any problems with the glass inside? Having steam or going foggy?

As this will be a real problem.

A: Usually, we use 5mm+9A+5mm double glass, you can take easy. Our double

glass is made professionally, no steam or going foggy between the double glasses.

Q2: All these doors and windows come with frames to mount on walls?

A: Yes, all the doors & windows include frames. Installing the windows and doors on

wall is OK.

Q3: The glass is broken with no reason, I’m afraid the rest will be broken.

A: The glass would be broken only because suffering from the impact force, but it

won’t break itself.

Q4: Can I use 6mm single glass instead of 5mm double glass?

A: It is better to use 5mm double glass, because:
    A) Sliding door looks ugly with single glass. There is a wide space for glass, if

you use single glass, we will fill so much silicon in it.
     B) 5mm double glass is safer than 6mm single glass.
     C) 5mm double glass is more soundproof than 6mm single glass.

Q5: Can you use rubber instead of glass silicon?

A: Yes, but it just can be one side, the other side has to be glass silicon. Because

it is not strong enough to use double rubber. And it is easier to fall off than the glass

silicon.

Q6: 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.

Q7: Do you know what U-value is?

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 2 30k=2w/(m 2k).

Q8: 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.

Q9: 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.

Q10: 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.

Q11: How many cubic meters would an order like this when packaged occupy in a container?

A: As for the container:
(1) 20ft container (20GP) can pack 26 cubic meters.
(2)The 40ft container (40HQ) can hold 54 cubic meters. So how about your idea? Besides, Do

you want to quote CIF or FOB or EXW price? Please kindly let me know.
