acceptable. To know the R-values of some selected materials, see table Thermal Characteristics of
Common Floor Protection Materials.
Example:
Required floor protection R of 1.00. Proposed materials: four inches of brick and one inch of
Durock
®
board
Four inches of brick (R = 4 x 0,2 = 0,8) plus 1 inch of Durock
®
(R = 1 x 0.52 = 0.52).
0.8 + 0.52 = 1.32.
This R value is larger than the required 1.00 and is therefore
acceptable
In the case of a known K and thickness of alternative materials to be used in combination, convert
all K values to R by dividing the thickness of each material by its K value. Add the R values of your
proposed materials as shown in the previous example.
Example:
K value = 0.75
Thickness = 1
R value = Thickness/K = 1/0.75 = 1.33
