Window and door Rough out Openings?

Question

Just wanted to know how much to add to the rough out opening for windows and doors also what are the window and door schedules on blue prints do the tell you the window size plus the rough openings.

normobrian,

Thanks that was what i was thinking you explained it to a t thanks for the input

Answer 1

The window/door schedule doesn't tell you the rough opening, it tells the finished opening. A 3'0" door means that the door itself is three feet wide. The frame is 3/4" on both sides. That makes the whole assembly 37 1/2". Windows are the same (add 1 1/2" for the frame). You'll want to add room to plumb the doors, too.

For a 3'0" door, the header would be 41". That's 36" for the door, 1 1/2" for the frame, 3" for the jack studs (support the header), and 1/2" to plumb the door. Some people allow more room for plumbing the door, but if your framing is plumb, you really don't need it. Your rough opening would be 38" for a 36" door (jack to jack, in the clear).

EDIT: For the first girl's answer, some blueprints give both rough opening and finished opening, but that is rare. Doors/windows come in standard sizes, like 3-0, 2-8, 2-6 for doors. The second guy said the same thing I said, add 2" (1 1/2" for the frame, and 1/2" for play to plumb it).

Answer 2

You really need to check with your supplier for your rough openings.

Interior doors are fairly safe with adding 2" to the nominal width of the door and 1 1/2" to the height, but even these can vary a bit if you are using and odd jamb material.

Exterior doors can vary depending upon the frame system and sill. 2 1/2" to nominal width and height is usually OK, but you can get into some real trouble.

Window schedules can have either a unit size, rough opening or call size depending upon the architect and the brand of windows being used. There is not a standard here, sometimes the call size is the rough, sometimes the unit size, sometimes the glass size, and sometimes just makes no sense at all. Andersen windows are a prime example, their 200 series double hung windows use the rough opening as a call size, 400 series use the glass size as a call size, casements and awnings make no sense at all.

Even if the architect does list rough openings, I would verify with your supplier as they do sometimes change as one window company buys another or changes the manufacturing process. Also, sometimes architects simply don't know what they are doing when it comes to the schedules. Also, you may choose to use a different brand of window or a different product in the same brand.

Don't argue with him. Let him do it his standard way. If necessary, he can trim down the side jambs and the bottom of the door to make it fit in the opening he created. And, just remind him that you will be putting in 3/4-inch plank flooring, so you'll need an additional 3/4 inch of clearance at the bottom. If it gets screwed up, it's his job to fix it. I had a home remodel done and had a pocket door installed between a bedroom and bathroom. I was going to have carpet in the bedroom. But, I was going to have tile installed, which would come up about an inch above the subfloor level (1/2 inch hardibacker and leveling compound, 1/4 inch thinset, and 1/4 inch tile). And, when they installed the pocket door, they didn't cut it to take into account the raised tile floor. We found out after they installed the tile that there wasn't enough clearance for the door to close. The only option at that point was to tear the jamb apart and remove the door, cut it, reinstall it, and rebuild the jamb.

Answer 6

1/4" is pretty tight, less than 1/8" on each side. Most framers make doors and window rough openings 2" larger, and shim to square the window/door.

Answer 7

Yes, blue prints should have a schedule to tell you window opening size. Interior dimensions of all rough-outs should be equal to the window size... or no more than ¼" larger.
