These vintage cast iron windows are perfect for adding a touch of old - world charm to your home or building. To install them, make sure the opening is the right size (800 x 1350 high). You can use regular tools for installation. When it comes to maintenance, clean them regularly with a mild soap and water solution to keep them looking great. Avoid using abrasive cleaners as they can damage the metal surface. Also, check the joints and connections periodically to ensure they are secure. These windows are quite sturdy, but handle them with care during installation and moving to prevent any chips or dents.
