What Is A Window Sill Drip Groove?
A window sill drip groove is a narrow, elongated channel on the edge of a window sill. The purpose of the groove is to channel water away from the window and onto the ground outside the building. The groove is usually located near the roofline of the building.
The drip channel is a small but useful addition to window sills. The inclined surface of a window sill is intended to direct water away from the window and down over the outer face of the sill, where it should fall to the ground.
The top surface of the window sill is designed with a channel in it to direct water away from the window and down over the outer face of the sill, where it should fall to the ground. It’s important that you try to install a drip channel as an integral part of your window sill so that you can have an accurate measurement for measuring off your window sill for your displays.
If you’re installing a drip channel on top of an existing sash, make sure that you are able to fit it onto your sash and then secure it (if necessary) before adding any glass. Do not attempt to glue on the drip channel when installing onto an existing glass frame because this could result in cracking or breaking of your sash glass later on.
The most common type of drip channel is called an extruded aluminum drip channel. It consists of a flat section that has been cut with an interior bevel followed by a rim that’s extruded at a 45-degree angle on one side. The channel is usually about 2″ wide and 1/8″ deep.
The channel length varies from around 2′ to 4′, with only one end angled. This is generally used when installing new displays or picture frames to windows or doors that have sills already in place.
