How Thick Should Interior Walls Be
Wall Thickness – A two-by-four wall stud is 3 12 inches wide, and 12-inch drywall is commonly put on both sides of an interior wall, bringing the wall thickness to 4 12 inches. However, walls containing plumbing, such as those below sinks, should be thicker than typical walls.

What is the thinnest internal wall possible?

The walls should be supported laterally at intervals of no more than 24 feet (7315 mm). Eight inches should be the minimum thickness of internal load-bearing walls (203 mm). The unsupported height of any wall made from adobe units should not exceed ten times the wall’s thickness.

How Thick Should Interior Walls Be Within Walls The majority of interior walls are constructed with a single skin of 110mm broad brick, with lime plaster on both sides bringing the wall thickness to around 150mm. There may be thicker walls at ground level and in areas with ducting etc.

  1. These walls ascend from the base to the ceiling.
  2. At solum level (the area under the ground floor), they may be constructed as a honeycomb wall to provide air to the joists and avoid decay.
  3. Occasionally, such as over stores, internal walls are constructed on strengthened joists or massive timber beams, and in these instances, movement is prevalent.

In older apartment buildings, the door frames in the interior walls are structural components. Two vertical timbers were linked with a horizontal timber lintel above the entrance to create “H”-shaped frames. Brick would be used to fill the area above the wooden lintel.

What should the wall thickness be?

Average Wall Width of Interior Walls – The majority of interior walls are framed with 2-by-4s with a standard width of 3 1/2 inches. Drywall normally covers both sides and is typically 1/2 inch thick, giving the wall a total thickness of 4 1/2 inches.

Typically, door jambs are machined to this width so that their edges are flush with the walls. The exception is bathroom walls, which are typically coated with 5/8-inch drywall. This adds 1/8 inch to the thickness of the walls surrounding the bathroom, but this can typically be compensated for by centering the jambs.

In basements and other locations requiring additional insulation, 2-by-6 studs are commonly used to construct walls. Each stud is 5 1/2 inches broad, so if you cover both sides of the wall with regular 1/2-inch drywall, the total thickness will be 6 1/2 inches.

Is a 4-inch wall adequate?

Wall thickness for structures with an RCC framework – For all types The minimum necessary wall thickness for non-load-bearing walls in a building with an RCC frame structure is eight inches (200 millimeters) for exterior walls and four inches (100 millimeters) for internal wall partitions to save costs.
