Rough opening refers to the framed opening of a window.

Rough opening doors and windows. In simplest terms a rough opening ro is a hole in a framed wall for a door or a window. Mark all the plates at once. For example let s say we want to frame a 6 8 x 3 0 front entry door. There are three simple rules to framing rough openings efficiently.

If you re going to frame a rough opening for a door then you ll need to know the unit size. For standard wood framed construction the rough openings for doors and windows is typically the actual unit size plus 2 1 2 inches in height and width. Add a 1x board if you need to decrease the size by 3 4 inches. Just add 2 to the width of the actual door size.

Framing rough opening sizes are really quite simple. The wall framing transfers the weight of the house down through the frame. And avoid toenailing when possible. You should add 2 1 2 to the height of the actual door.

For example if you need to make the height 1 2 inch smaller rip down a 1 2 inch strip of plywood and install it on the sill. You re bound to miscut something because it s tough to see the actual opening. Whenever wall framing is interrupted for an opening the structural functions of the wall frame must be accomplished by the ro framing. Most door and window manufacturers provide ro dimensions and we build ros to those sizes.

So if you have a bedroom door that is 30 wide which is considered a 2 6 or 2 6 door just add 2 to the width and frame it 32 wide. The best way to fill in a window rough opening is by installing additional lumber boards. Sill the window sill sometimes called a saddle creates the bottom of the window rough opening.

Framed openings have a header across the top a sill plate across the bottom and vertical trimmers between the header and sill at each. This will give you room to space the door frame off of the sub floor.

Instead feel the window opening through the house wrap and mark the cuts first. Depending on the size of the opening a window or door can have a few as one jack stud on either side or multiple jack studs with large openings that carry higher loads.
