Wall Systems and R values?
insulation r values
The insulation R values of the individual wall framing materials, do not give an accurate measurement of the average for the whole wall system. The following are 3 methods used to measure the R value insulation factors for your home.

Clear Wall R Values:

Clear wall R Values are the R values of a wall with just the studs. This doesn't include framing, windows, doors and exterior corners.

Center of Cavity R values:

Center of cavity R values are the estimate of cavity space area between the studs.

Whole Wall R Values:

Whole wall R values are the estimation of R values for both the clear wall system and the center of cavity system. It takes into account additional materials such as windows, door and exterior corners. Whole wall systems are generally the most reliable method for determining R values for insulation of walls.

 

Facts About the R-value of Wood Wall Studs
calculating r values windows Approximately 11% of your home is not insulated properly due to wood framing however, wall studs are a fact in home construction. Before you cover up the wall studs, making house insulation diagrams for any future reference is a good idea.

The r-values of wood studs act as a thermal bridge. The r-values of wood can create a cold area in the insulation where the wood stud meets the sheetrock. The cold spots can compromise the insulation and lower the effective average R-values of the whole wall. In addition to the poor r-values of wood lowering the R-values of the wall, a cold spot may lead to condensation problems. Moisture could condense through wall studs, which generally have the lowest insulation r-values, and other framing materials of the home. If moisture does get into the wall cavity, moisture condensation can begin where the cold r-values of wood studs meet the sheetrock.
The r-values of wood wall studs are linear and are measured in terms of inches. However, wood wall studs generally lower the r-values of your insulation.
The r-values of wood are specified as 1.25 per inch.

A 2X6 wall studs r values are measured as,
5.5" X 1.25. The r values = 6.875

A 2X4 stud wall studs r-values are measured as,
3.5" X 1.25. The r-values = 4.375

To help protect against moisture entering your home and further lowering your homes r values, protect your home with recommended insulation r-values Dimpled Membrane. calculating wall r-values provides a permanent barrier around your home and helps protect your homes r-values. Just 4% moisture in your insulation could lower its thermal efficiency, in that area, by up to 70%.
