There are a couple of ways to size door openings in a masonry wall.

Rough door opening size in concrete wall baement.

Let s use a 5 double door to do our figuring for the rough opening width size. I m trying to work from that and add for the wood framing that i would need to get to the concrete opening size. Just add 2 to the width of the actual door size. We just add 2 to the door size just like any other standard size door.

The prehung steel doors at the homecenters call for rough opening 2 more which is probably the exact size of concrete alone. I m being asked to supply a masonry opening size for a pre hung external door that i want placed in a new precast concrete basement wall superior walls. 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. Frame the rough opening to 3 inches wider than the garage door size you have selected.

Interior knockdown frames that wrap wall. B opening height 1. For example let s say we want to frame a 6 8 x 3 0 front entry door. A opening width 2.

Rough opening with 2x still in opening is approx 35 5x80. A 6 foot 8 inch wraparound door frame will fit a 10 course high concrete masonry opening as shown in figure 1. The 6 8 stands for 6 8 tall and the 3 0 stands for 3 0 wide. Therefore the rough opening would be 82 1 2 tall by 38 1 2 wide.

Wraparound door frames are most often used with 4 and 6 inch thick walls although they also are available for 8 inch and 10 inch wall thicknesses. If you are installing a 9 wide door the opening will be 9 3 wide. The rough opening would be 38 x 85. You should add 2 1 2 to the height of the actual door.

Framing rough opening sizes are really quite simple. For a 3 0 x 7 0 door frame. 60 wide door 2 62 rough opening width. Frame the rough opening to a height that is 1 5 taller than the door that you have selected.
