Interior walls are measured, cut, framed, and raised, in the same manner as exterior walls. However, you will use 2"x 4" construction for interior walls as opposed to 2" x 6" construction. Studs for interior walls are longer as they don't set on a sill plate. This also means that there is no nailing surface to attach the walls to the slab. Therefore, the wall must be secured directly to the slab.

  1. What is the measurement of the interior walls?

    • The height of the interior walls will be the same as that of the exterior walls.

    • Measure up from the slab to the top plate.

  2. How to calculate the length of interior wall studs.

    • Calculating the length of the studs will vary slightly as there is no sill plate to take into consideration.

    • Stud length = total height of wall less Top plate, and Bottom plate.

    Interior Walls Have No Sill Plate Therefore The Interior Studs Will Be Longer Than Exterior Studs

  3. How to calculate the length of the wall.

    • The length of each wall will depend on the dimensions of the room you a building.

    • If you have a room that will be 12' long, then you must build a wall that measures 12'4".

    • The additional 4" takes 3 1/2" for the width of the lumber in to consideration, and 1/2" for the interior sheathing.

  4. how to position door rough openings.

    • Decide whether the door will open into the room or out from the room.

    • Decide whether the door will open from the right or left.

    • Take into consideration any furniture that will be in the room or just outside of the room as well.

    • Once you have answered the above questions, place the rough opening accordingly.

  5. How to design rough openings for interior doors.

    • Rough opening for interior doors on non-load bearing walls will consist of a stud on either side and a ladder header.

    • Again rough opening will be 2" taller and 2" wider than the actual size of the door assembly.

    • The actual height of the rough opening will be measured from the slab not from the top of the bottom plate. That portion of the bottom plate will be removed at a later time.

  6. How to cut out wall parts.

    • Top and bottom plates will be cut to the length of each wall.

    • Studs will be cut to length and placed 16" on center just like exterior studs.

    • Cripple studs for ladder headers will fill in the gap to the top sill.

  7. How to cut out knockouts for water walls.

    • Place bottom plate over the exact location that it will be installed and mark out areas that need to be cut out for water and drainage.

    • Once the bottom plates have been marked, use your saws-all or jig saw, to cut out the exact location for the pipes.

    • If you are cutting out for drain pipes, you will need to cut that portion of the bottom plate out all together.

    • Below are examples of knockouts on installed interior walls.

  8. How to frame and raise interior walls.

    • Align both bottom and top plates together.

    • Mark the location of the studs onto both plates.

    • Place bottom and top plates on the slab facing one another at a distance approximately equal to the length of a stud.

    • align the studs on their marks and nail nail them to both plates.

    • Insert 2 Round Head Framing Nails at each end.

    • Construct and nail the rough openings.

    • Once you have completed the framing of the wall, mark its location on the slab.

      • Measure the exact location of the wall on the slab.

      • Using your chalk line and lining up the marks you have just made, snap a line.

    • Since interior walls are constructed of 2" x 4"s, they are much lighter and much easier to raise. Depending on the length of the wall, you may be able to frame each wall in its entirety.

    • Raise the wall and line it up with the line you have just snapped.

    • Once the wall is lined up, secure it to the exterior wall by nailing the corner stud to the box intersection.

  9. How to secure the wall to the slab.

    • There are a couple of ways to secure walls to a slab.

    • You can use a concrete Hammer Drive Tool to insert nails directly into the stud and through the slab.

    • The Hammer Drive Tool consists of a chambered hammer, 22 caliber charges, and concrete nails.

    • Once the charges and nails have been inserted into the hammer, place the tip of the hammer over the surface to be nailed. Hit the head of the hammer with a small sledge hammer (be sure to wear ear and eye protection.)

    • The charge will be ignited and the force will drive the nail through the bottom plate and into the concrete.

    • Different caliber charges must be used for different sized nails and different densities of concrete.

    • A second option is to use a hammer and concrete nails.

    • This method requires a little more effort but it is also effective and somewhat less costly.

  10. How to brace an interior wall.

    • Nail the top of the brace to the exterior wall and the bottom of the brace to the bottom plate of the interior wall.

    • Nail a second brace to the top plate of the interior wall and the other end to the bottom of the exterior wall.

    • Both braces will cross one another.

    • These cross braces will remain until the roof is up.

  11. How to install a Cap Plate.

    • The cap plate helps to tie all of the walls together by securing the joints together, and it also creates a stronger surface for the roof trusses.

    • The key to laying down a cap plate properly is to cover all joints created by joining wall sections together. This also applies created by intersecting interior walls with exterior walls.

      • Begin by covering the

        All Joints Of Wall Sections Must Be Covered By A The Solid Portion Of The Top Plate
