Oh, you think it is quite comprehensive .. Glass and aluminum alloy is actually calculated, the area of the glass is actually the total area of the window, with you how much is not much relationship with the aluminum alloy (because the glass is not a few pieces Put together to use), the main decision whether the price or what style you use .. In general, the style of the window so then three or four, any kind of aluminum alloy in the amount of the proportion of the total area of the window is relative The same way .... and then reverse the way to calculate the style of this window a square meter with the number of aluminum alloy .. then add the price of the glass is the usual said per square meter how much money ..... So the market is certainly a reasonable reason ah ... Oh
