    Ways of glazing metal sashes

    There are two ways for which you can replace broken glass with new ones in metal sashes. You can either do glazing on the outside of the metal sashes or on the inside. Remember to protect your fixtures and furniture and other household products before glazing metal sashes. This is because there may be spilling or dripping of putty which will damage the finish of the bathroom fixtures. You can cover the fixtures with plastic sheets and for furniture etc, you can always move them away from windows during this process.

    Alternate method

    For glazing metal sashes on the inside, you should first remove the broken glass by unscrewing metal beading and glazing strips. After this, you need to ward off the remaining putty and clear the glaze.

    Reapply the new putty on the metal sashes in similar way mentioned above. Then install the new glass. Remember to fasten the beading and glazing strips again. However, take caution when doing this as you do not want to break the glass.
