Rough Opening (RO) is a measurement of the wall opening that provides clearance on three sides of the window for proper installation, insulating, and shimming.

What is a rough opening for Windows?

A rough opening refers to the framed opening of a window. A window frame, however, has a header across the top, a sill plate across the bottom, and vertical trimmers on either side.

How do you fill a gap between a wall and a window?

If you have very large gaps around a window, you can fill them using expanding foam. Expanding foam is perfect for filling large gaps around windows as it allows for a degree of movement without cracking or breaking. It can also provide a good moisture barrier between the brickwork and the window frame.

How much clearance should be left between the frame opening and window once it has been installed?

All windows need a little extra wiggle room to allow you to shim the window and square it in the opening. When ordering a replacement window, subtract 1/4 inch from both the width and height to determine the exact replacement size. Keep your original measurements in case the manufacturer recommends a greater clearance.
