FLOOR PROTECTOR
Your wood stove should be placed on a 1 inch, non-combustible surface with a k factor of 0.84. For
multiple layers, add R-values of each layer to determine the overall R-value. The R value for the
required board is 1.2. If there is a horizontal section of chimney connector, the oor protector should
go under it and 2 inches beyond each side
Convert specication to R-value:
k-factor is given with a required thickness (T) in inches: R=1/k x T
C-factor is given: R=1/C
Example:
If the oor protector is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a “k”
factor of 0.29 the total R-value of the system is:
4” brick C=1.25, R=1/1.25=0.8
1/8” mineral board K=0.29, R=1/0.29 x 0.125=0.431
Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231
Total R is greater than 1.2, the system is acceptable.
The oor protector should exceed the stove as follows:
