What does RO mean in Windows?
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.
How do I determine the size of the header in Windows?
Important. Sizing a window header individually, using span and load tables, is always the most accurate way to determine header size. This helps to address the innumerable factors that can change with windows, including sizes, shapes, and loads. Contact a structural engineer, licensed contractor, or architect.
