The difference between casement Windows and sliding Windows in appearance mainly lies in the combination with the overall style of the building. Casement Windows can be made into any facade effect of lines because of their greater flexibility in subdivision. For floor-to-ceiling Windows with large subdivision, the opening window only accounts for a small part of the whole window, so it is more suitable for high-end real estate with strict requirements for the overall effect of the building. Especially in line with the architect's pursuit of large division, spacious and bright, transparent effect is good, the appearance of smooth coordination of the building. Because the opening of the window can only be pushed and pulled horizontally, it is difficult to match the fixed glass with a large partition, and it is generally more suitable for the opening of the factory or rural family buildings with more distinct horizontal and vertical lines.
