How to Make a Parting Strip

If you looked at windows with sashes, there is usually a thin piece of wood located on each side of the window. Those pieces are called parting strips. Parting strips block outside air from entering your home. In older homes or windows, parting strips might be damaged, which can cause a draft. Save money on your heating and cooling bills by making your own parting strips.
