What size wood wall studs are used for a manufactured/mobile home?
Thursday, June 14, 2018
Based On Performance-Based Code
The U.S. Department of Housing and Urban Development (HUD) governs mobile home construction, and their HUD-code is unique in two aspects: it is the only nationwide building code and also primarily a performance-based code. Most building codes are largely prescriptive, meaning that they specify exactly the materials and methods of construction that must be used. A performance-based code instead sets the performance standards for things like wind resistance, structural loading, weatherproofing, and insulation. This gives manufacturers some latitude in how they meet the standard.
Depends On Wind Zone, Insulation, And Customer Preference
The walls studs of a manufactured home may be nominal 2x6, 2x4, or 2x3, depending on the wind zone, thermal zone, and price point of the home. Hurricane zone homes must be structurally stronger, colder thermal zones need more room for insulation in the walls, and premium home buyers want a 2x6 stud wall. Some states also have what are called “HUD overrides” that set a minimum 2x4 stud size.
