If the window is a fix window it might cost you as less as Rs 400 per sq. ft. If the same window is a openable sliding window with a small size that sq. ft, price can go upto2100- 2200 sq. ft. Then again it depends on which system of opening window we are taking or if it is an insulated or Non Insulated series very much depends on every house how many fix windows and how many sliding windows are there that will decide the Sq. Ft. price of that particular project. Every House and every project has a separate sq. ft. rate depending on the design and opening and requirement of the project As well as the colour and finishing choices of the  profile and the choices of the glass thickness and the Glass  specifications. Windows width & Height and any special hardware required like Key Locking, Door Closure etc.  So many variants are there. So saying a Sq.
