Making windows involves cutting the frame from wood, vinyl, or aluminum, then installing the glass pane into the frame. The frame is fitted with weather stripping to seal the window, and caulking is applied to secure the glass. For double-pane windows, two glass panes are installed with an insulating gap between them to improve energy efficiency.

Window construction requires cutting the frame, installing the glass, and sealing the edges with caulking and weather stripping. Double-pane windows involve adding an insulating gap between two glass panes for better energy efficiency, helping to reduce heating and cooling costs.
