Rough opening is an opening in a wall, or the framework of a building, into which a door frame or window frame, subframe, or rough buck is fitted.It is a measurement that a manufacture needs for installment of their component applications.
Any opening in your home. ie- window frame and rough opening (use minimal expanding foam to not damage window) soffit area of roof, garage door opening, basement opening for HVAC etc...
All rough openings for doors or windows should be as close as possible to plumb and square or your door or window wont be able to be installed properly. As long as you have enough room in the opening to iinstall it square and plumb it'll work fine but if your opening is way out of true, even if you install the window level and plumb it just wont look right.
It can vary between manufacturers. Contact them before framing.
Windows are measured in the usual units of the country, whether metric (millimetres or metres) or imperial (feet and inches). The part of the window that is being measured needs to be specified. It could be: * the rough opening - the width of the hole in the wall into which the window will be fitted * the frame size - the width between outer parts of the window frame * the inside reveal to inside reveal width- the width between the timber trim around the window on the inside of the wall * the daylight opening - the unobscured glass width * the sash dimension - the dimension of the opening part of the frame All these measurements have different uses and by, for example specifying only the rough opening width, the exact type of window frame does not need to be specified.
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.
