Window Glass
Replacing a pane-especially a small onein a window sash isn’t difficult. After carefully removing the old glass and measuring the opening, you can either cut new glass to size yourself or have it done. Install it in the same way the original glass was installed.
CAUTION: Take care when working with glass. Wear heavy gloves and safety goggles if you’re removing
shards. Before removing broken glass, tape newspaper to the inside of the sash to catch any fragments. Pad glass with several layers of newspaper when you’re transporting it and dispose of glass fragments immediately Wood sashes. In wood sashes, tiny metal glazier’s points and glazing putty on the outside of the window hold the glass in the sash.
The steps in reglazing a wood sash are shown below. After you’ve removed the glass, you’ll need to chisel
out all the old putty If it’s hard, soak it with linseed oil or gently heat it with a propane torch.
To determine the size for the new pane, measure the width and height of the sash opening and subtract 1/8 inch from each dimension. Measure the sash at several points to allow for its being out of square.
NOTE: Since wood sashes are re-puttied from the outside, you may have to remove an upper-story window or get up on a ladder to reglaze it.
Metal sashes. In windows with metal sashes, glass may be held in place in several ways. Metal casement windows may use putty or a combination of putty and metal spring clips. Glass in these windows is re-placed in much the same way as for wood sashes. In other windows, the glass is secured with rubber seals, a rubber gasket, or beveled metal or plastic snap-out moldings.
