Point and Counterpoint


In the recent discussion of wood skyscrapers (full disclosure: I think they’re a terrible idea) I have noticed any discussion of the extent of exterior maintenance necessary to prevent wood from acting like the biological material it is. A masonry curtain wall can go thirty years with no maintenance and not fail: a lot of the facade repairs we are involved with are on buildings that went fifty years or more with zero or minimal exterior maintenance. A glass curtain wall can go fifteen years before its sealants completely fall apart. How often will we be painting wood curtain walls?
