Construction Basics Part 1: Framing the house.
Wall Basics • Most exterior walls are framed with 2x6s because they are the primary weight bearing walls of the house. Additionally they need the extra space for the insulation of the house. • Interior walls are framed with 2x4s because they aren’t weight bearing, and they don’t need insulation.
Sill Plates • When making a wall, the bottom piece of wood is made out of a sill plate. • Sill plates are pressure treated pieces of wood because they sit right upon the concrete • The pressure treatment is used to help prevent rot, bugs, and water damage. • You can tell a sill plate from other wood because it often appears green.
Studs • Studs are the pieces of wood that make up the wall. • The are attached to the sill plates and the top pieces on a sixteen inch center basis. • This means that the center of one stud is 16 inches from the next.
After the wall is made • Once the wall is made, it is moved into place and plumbed. • When plumbing a wall it needs to be level both horizontally and vertically. • Once it is plumb, it needs to be fastened to the concrete, and kept plumb while the other walls are being constructed.
