Yes, you can. An ingenious way of restoring energy efficiency to your high-rise building is by replacing the glass in the double glazing than replacing your entire window. A double glazed window consists of two glass panes separated by an air space or inert gas. This double-glazed unit is then fitted into your window frame. Though they are highly durable, it is possible for your glazing unit to “blow”, necessitating a replacement. Replacing the glass in your double glazing requires removing the entire unit and fitting in new glass panes. This method is budget-friendly and can address the energy inefficiency of your windows. The window assembly must be resealed after the glass has been replaced. Another cost-effective option is to buy a double glazed unit of similar size to fit into your window frame.
