ALTERNATE FLOOR PROTECTION
All floor protection materials must be non-combustible ie. metal,
brick, stone, mineral fiber boards). Any combustible material
may not be used.
The easiest means of determining if a proposed alternate floor
material meets requirements listed in this manual is to follow this
procedure.
R-value = thermal resistance
k-value = thermal conductivity
C-value = thermal conductance
1. Convert the specification to R-value;
a. If R-value is given, no conversion is
needed.
b. If k-value is given with a required
thickness (T) in inches: R=1/k X T.
c. If C-value is given: R=1/C.
2. Determine the R-value of the proposed alternate
floor protector.
a. Use the formula in Step 1 to convert
values not expressed as R.
b. For multiple layers, add R-values of each
layer to determine overall R-value.
3. If the overall R-value of the sustem is greater
than the R-value of the specified floor protector,
the alternate is acceptable.
EXAMPLE:
The specified floor protector should be 3/4 thick material with a
k-factor of 0.84. The proposed alternate is 4 brick with a C-
factor of 1.25 over
1/8 mineral board witha k-factor of 0.29.
Step A. Use formula above to convert specifications to R-value.
R=1/k X T= 1/.84 X .75 = .893
Step B. Calculate R of proposed system.
4 brick of C-1.25, therefore
R brick = 1/C = 1/1.25 = 0.80.
1/8 mineral board of k = 0.29 therefore
R mineral board = 1/.29 X 0.125 = 0.431
Total R = R brick + R mineral board=
0.8 + 0.431=1.231
Step C. Compare proposed system R = 1.231 to specified R of
0.893. Since R is greater than required, the system is acceptable.
