The debate rages on over whether the pocket sill or the sloped sill is the best choice for your Cincinnati home. Before you can make a decision on which type of sill you want, you must first learn the major differences between the two styles. This guide will help you understand why you might prefer one or the other in your next window investment.

What is the Sill?

Before you can fully appreciate the differences between sloped sills and pocket sills, you must first learn what a sill is. In window anatomy, the sill refers to the bottom section of the window that supports the sliding sections of glass when the window is closed. Most people are familiar with cleaning their window sills in the spring because dust and debris build up along the bottom track throughout the rest of the year.

What is a Pocket Sill?

Now that you know which part of your window we are talking about, we can look at pocket sills in more detail. A pocket sill is a design which allows the window sash, or moveable portion of the window, to rest down inside of a pocket created in the frame. The result is that when the window is fully closed, the bottom rail of the sash is mostly hidden and you get more visible glass. In addition, since the window sash is resting in an enclosed area, it is protected from drafts and other weather, and it is more supported by the window frame, for a more durable installation. However, it is true that pocket sills sometimes struggle to drain water if it does build up in the pocket, and the pockets can fill with debris that needs to be cleaned regularly to create a perfect seal.

What is a Sloped Sill?

The sloped sill is a newer design that is growing in today’s window replacement industry. It uses a simpler mechanism for keeping rain and air out while protecting the window’s integrity. With a sloped sill, a small metal strip runs along the bottom edge of the window, meeting the sash. It gently slopes outwards and away from the house. This ensures that rain and debris are pushed away, and do not collect in the sill. Sloped sills typically have a lower profile than pocket sills so you gain some window space, and they don’t have to use a complex drainage system so they can be better insulated. You’ll prevent the buildup of debris and any pests that might nest in a pocket sill as well!
