History of Sills
There was a time when all interior window sills were made of wood. That was back in the days when all windows were made of wood. In fact, those wood window sills usually were part of the window. Not only did the wood window sills look good, they helped prevent water and moisture from entering the wall.
When aluminum windows, and later vinyl windows, started to be used, the wood window sill began to disappear. These new types of windows didn't come with a sill — if a builder or homeowner wanted to provide a sill, he had to create and install his own. Because this was a labor-intensive task, wood window sills are rarely installed. It's been easier and cheaper to use drywall as a sill.
Drywall was never intended for horizontal surfaces, especially surfaces that are likely to come in contact with moisture. You see, anytime condensation forms on your window frames or on the window glass, it usually ends up dripping on the drywall. Since the drywall sill is horizontal, the water sits there and soaks into the drywall. Or worse, the water finds its way between the window and the drywall and into your wall. This unseen water can rot your wood framing as well as cause unhealthy mold and mildew to form.
This sill problem is no secret. Many builders have been trying various solutions to the sill problem. However, whether they install wood, marble, or solid surface sills, each of these solutions tend to be costly in terms of materials and labor.
