A "rough opening" is the term for the opening in a wall into which a door or window will be fitted. It is slightly larger than the outside of the frame of the door or window to give some tolerance (space) to install it and get it in the exact position and square. It is measured between the structure to which the door or window will be fixed, such as the studs or masonry. The amount of tolerance between the frame and the structure varies depending on the type of construction and how accurately it is built, but is often in the order of 10mm all around the frame. An air seal and expanding foam are sometimes installed into this gap , and linings or architraves, and claddings cover it.
