The rough opening for a 36-inch interior door is the size of the opening that is prepared before the door is installed. It is the space reserved for the door in the wall. To determine the size of the rough opening, it is important to measure the door itself. The rough opening should be slightly larger than the door, allowing for a small gap between the door and the wall. This gap is necessary to provide room for the door to swing open or close and to ensure that the door is properly secured in the wall.
Measure the Door
The first step to determining the size of the rough opening is to measure the door itself. Measure the width and the height of the door in order to determine the size of the rough opening. The rough opening should be at least 1/2 inch wider and 1/2 inch higher than the actual door.
Prepare the Rough Opening
Once the measurements of the door are taken, the rough opening can be prepared. The wall should be framed out to the proper measurements and then secured in place. If the wall is not properly framed, the door may not fit properly. Additionally, the wall must be level and plumb in order for the door to open and close properly.
Install the Door
Once the rough opening is prepared, the door can be installed. Make sure that the door is level and plumb and that the hinges are properly secured. Additionally, the door should be shimmed so that it is properly secured in the opening and has a tight fit. Once the door is installed, the door jamb should be secured in place and the door should be tested to make sure that it opens and closes properly.
Conclusion
The rough opening for a 36-inch interior door is the size of the opening that is prepared before the door is installed. It is important to measure the door itself and prepare the rough opening to the proper measurements. Once the door is installed, the door should be shimmed and tested to make sure that it opens and closes properly. Following these steps will ensure that the door is properly secured in the wall and functions properly.
