E5 | All About Windows | Ask This Old House

We explain everything about installing, maintaining and repairing windows. Kevin explains the anatomy of a window: the sash, stool, sill, jamb, head and side casings, apron, trim and stiles. Kevin takes a deep dive into the history of glass, the most important part of any window. Kevin and Tom take you through how safety glass works and then we repair several windows in different locations.
