What type of wall is in my house?

Type of wall in your house depends on age, location, and construction method, but most modern American houses have interior walls made of wood stud framing with drywall or plasterboard, and exterior walls made of wood studs with insulation, sheathing, house wrap, and exterior siding like vinyl, brick veneer, or stucco. Interior partition walls are typically non-load bearing walls made of 2x4 wood studs spaced 16 inches apart covered with drywall. Load bearing walls that support floors and roof may be made of thicker 2x6 studs or include beams. In older houses built before 1950s, walls may be lath and plaster rather than drywall. In some regions, especially Florida or Southwest, exterior walls may be concrete block or concrete with stucco. Townhouses or apartments may have concrete or metal stud walls for fire separation. If your house is brick house, exterior walls may be solid brick or brick veneer over wood studs. To determine exact type, you can check attic or basement to see framing, or look at thickness of wall near doorway.
