One of the primary complaints regarding initial sash windows is their bad thermal insulation. Historically, these windows included single-pane glass, which offers minimal resistance to heat loss. During the repair process, there are two primary ways to address this:

2. Slim-Profile Double Glazing
In some cases, the original sashes can be modified to accommodate "Slimlite" or vacuum-sealed double-glazing units. These units are thin sufficient to fit into the original glazing bars, supplying the thermal advantages of modern-day windows without the large look.
