Mix it up! beautify those large openings. Use your own creativity or ask us for suggestions in adding an urbane touch to your house. While most common combinations are fixed windows going on the sides and top/bottom of the sliding windows, an occasional casement (normal or top-hung) in combination with fixed windows are some things we deal with, based on our previous experiences from the customers all around Hyderabad. The best use case for the combination windows, we came across from our experience would definitely be farm houses in and around the city.
