Sash windows require lots of weatherstripping to keep out wind and cold. This is particularly true if the window opens vertically rather than horizontally, as the sash is able to move upwards and downwards as well as out and in. The weatherstripping you use must be able to withstand friction, temperature changes and wear, yet allow the window to open and close without restriction. Pam employs felt strips or foam tape to seal the bottom of the lower sash and she also installs V-channel weatherstripping around the frame.

Pam presses an elongated rope or rabbet of glazing compound around the glass to secure it within the sash. She also places glazier's facets within the sash, equally spaced across both sides. They shouldn't exceed 12 inches apart.
Pam adjusts the cords and chains if necessary. She then cleans the meeting rail and the ironmongery for sash furniture, lubricates the pulley axles with oil for the pulleys, then puts in the new sash stop.
