Why does Platinum Series Homes use 2 x 6 exterior walls, when other builders use 2 x 4 walls?
A. Platinum Series homes use 2 x 6 exterior walls for a couple of reasons. 2 x 6 walls are used mainly for wall stability. Some builders use 2 x 4 walls and either R-Board or a sound deadening board as an exterior sheathing. Both of these items have no real structural stability and could easily allow the 2 x 4’s to shift and move. Platinum Series Homes uses 2 x 6 with a _” OSB sheathing, which is a laminated wood sheet with structural properties. The second reason Platinum Series Homes uses 2 x 6 exterior walls for insulation purposes. Platinum Series Homes can install R-19 insulation in the exterior walls, helping to increase the energy efficiency in the home. Some builders will tell you that 2 x 4 walls can increase the interior size of the home. I would prefer for the energy savings as compared to the minimal few square feet of space added to your home.
