Have you noticed a lot of metal bars standing tall in the new addition? I bet you have!
The metal bars will serve as the structure and support for the walls of the classrooms, hallways, and other rooms in the new addition. Individuals called Framers have installed these metal frames in all the locations where there will eventually be a wall. After the Framers are finished, Drywallers will come in and install drywall on top of the frames. Drywall is a thick white board that you can buy in large sheets. When you touch a wall inside your home or school, you are likely touching drywall.
