He added that builders who understand what areas need to be blocked often use the wrong materials.

When considering the size of the studs to use, it may be best to avoid any such problems by using the larger 2x4's. In places where there are masonry elements such as brick or concrete, the siding can be lowered, but still no less than 2 inches from those elements. (See “Bracing Walls for Wind,” Jul/13.) Rise/run problems can arise where the builder doesn’t have enough horizontal space for a planned stairway. But state-mandated contractor training has also played a role. To further resist racking, builders can also use flat-framed 2-bys run diagonally on the underside of the joists . Typically, diagonal post bracing is required (photo at right ). Bypassing this code requirement can lead to the basement wall members soaking up moisture. All doors must also be fire-rated and installed to local fire code specs. If a ceiling slopes, such as with an attic room, only the floor space where the ceiling height is at least 60 inches may be considered habitable. They usually have to add a second layer. Earth, no matter how dry it may appear to be, is rarely 100-percent dry. Copyright ©2006-2020 do-it-yourself-help.com. Association of Bay Area Governments: What Is A Shear Wall?

For a 2 x 4 wall, use a 2 x 4 block, for a 2 x 6 wall, use a 2 x 6 block; its that simple. If you build an exterior retaining wall from wood, that wood must be pressure-treated. This may require blocking between studs on tall walls or when panels are run horizontally. Measure the length for the new wall. If you must build the new wall parallel with the joists, try to place it aligned with an existing joist so the top plate can be nailed directly to it. Code requires nailing along all panel edges, and that may require blocking between studs on tall walls or when panels are run horizontally. According to the International Residential Code table R602.3(5), the spacing of the studs in any particular wall will vary depending on whether it is load bearing or not, its height, and the size of the lumber used. If a new partition wall will be built perpendicular to the ceiling joists, you can choose any placement that suits your purposes. Find the shortest measurement from floor to ceiling and build your new frame to this height. Nail through the plates into the studs using two 16d nails on each end. See code section R302.11) for specific locations and approved materials. But if you want wood, then choose pressure-treated wood, preservative-treated wood, or naturally durable wood. Local building authorities generally defer to the house’s architect unless there is a disagreement. While pressure-treated wood is twice or even three times more expensive than conventional kiln-dried lumber, your gain is the peace of mind in knowing that your project will not be affected by moisture or pests such as termites or carpenter ants. This means that the studs are set 16 inches apart along the two plates, with the center of each stud placed at each 16 inch mark. Get everyone on the same page and streamline code research. Interior wall framing step by step: Step 1: Select the top and bottom plates . In a closed environment of this type, wood rot and devastating mold can quickly set in. As wall height increases, so does the need for a beefier structure. What may seem like a job for a professional, is actually not too advanced for the average homeowner.
