What is the degree of a window sill?
So, what is the proper sill angle? For optimum rain drainage, a window sill should have a 3-12 or 3″ by 12″ slope or pitch. The slope of 3-12 indicates that for every 12 inches of horizontal distance (run), the vertical measurement (rise) is 3 inches. According to Table 1.1, this equates to a slope of 14 degrees.
Should a window sill be sloped?
The sill on a rough opening should be sloped so it can direct water that has penetrated the building envelope back to the outdoors. This can be accomplished by cutting the cripple studs at an angle or by adding a sill-wedge or sloped pan after the rough opening has been framed in.

How do you determine the slope of a sill?
Using a ruler or tape measure, measure the vertical distance between the 2-inch mark on the square and the top of the sill. 3. Find the angle on the table below, which includes the most common sill angles. If the measurement falls in between the numbers on the table, that means the sill angle is in between, too.
What is a sloped sill adapter?
Sloped Sill Adapters are designed to fill in the exterior gap between the bottom of a vinyl window and an existing sill. They come pre-taped and pre-scored, allowing for a quick and easy install.

What is a slope sill?

As Addicted to Decorating discovered, miter cuts are seldom necessary.
Why are window sills wider than the window?
This is why windows and sills are typically designed with a projection of at least 20 millimeters. This creates a larger horizontal surface so that water drops will break free before they can migrate into the structure. On the exterior of a home, this overhang is vital to protect the wall from water intrusion.
Why are brick window sills angled?
Bricks are not always flat, smooth surfaces that allow water to flow freely.The brick should be angled to a greater degree to ensure water flow. This angle was quite common in brick homes built in the last twenty years (1990 to 2010). My home was built in 1964, and the brick window sills were angled more.
Can I replace a brick window sill with wood?

horizontal, the slope from the ends should be 1/8 in. (3 mm) to 12 in. (300 mm) toward the center of the sill. For sills longer than 4 ft ( 1.2 m), the slope should extend for at least a distance of 2 ft (600 mm) from the ends, see
