Astrapia Upvc Tech Pvt. Ltd. is based in India and lists windows and doors on Global Trade Plaza. Casement windows are described as operating vertically or horizontally with a simple mechanism, suitable for both larger and smaller openings, and vertical casements are noted for bringing light and sound into spaces that usually lack them. Openable doors are offered as single-sash or dual-sash (French door) configurations with multi-point locking and threshold options including regular, low and no threshold. Sliding windows operate on a horizontal track with sashes that glide along the frame and use window glazing. Fixed windows are single pieces of glass fitted in a frame with no openable sash or hardware, used to connect indoor and outdoor areas or to replace interior walls. Fixed windows are also noted for industrial and residential use. Buyers can send an enquiry through Global Trade Plaza.
