Cut around the perimeter of the glass, roughly 1 inch from the edge. Then, gently move the glass into place in the rabbets, the l-shaped grooves in the window frame, where it will sit.

The spacer bar usually contains an ingredient called desiccant which helps draw moisture out of the gap and prevent condensation. The desiccant's capacity to eliminate moisture from spacer bars decreases, condensation can form between the glass panes. This is a common problem with double glazing that's been poorly made.
