2x4 and 2x6 Standard Framing (16" or 24" oc)
The 2x4 and 2x6 frame wall at 16" on center are standard systems. A 2x6 wall at 16" or 24" on center is often used in residential construction in Minnesota to meet current building codes and performance standards. This wall system includes siding, sheathing, 2x6 wood studs, single bottom plate, double top plate, R-19 fiberglass insulation, vapor retarder, and interior finish gypsum board. The advantages of this method include familiarity by the trades, easily available products, and the ability to achieve a relatively high R-value. The disadvantages of this system include the use of more material than necessary to meet engineering requirements, and the additional time required for framing (as compared to some other systems). For cost and environmental implications see the Cost and Life Cycle Analyses below.
