3.2. FLOOR PROTECTION<br />
The floor protection extended beyond the hearth must have an R value greater than 1 (see Figure<br />
3.2 and Table 3.2).<br />

USA<br />
E 18’’ (457 mm) – Note1 16’’ (406 mm) – Note 1<br />
I 8’’ (203 mm) N/A (Canada only)<br />
J N/A (USA only) 8’’ (203 mm)<br />
Table 3.2<br />
Note 1: From door opening. The depth of a non-combustible shelf in front of the insert is<br />
included in the calculation of the floor protector’s dimensions.<br />
Convert specification to R-value:<br />
k-factor is given with a required thickness (T) in inches: R=1/k x T<br />
C-factor is given: R=1/C<br />
Example:<br />
If the floor protector is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a k<br />
factor of 0.29 the total R-value of the system is:<br />
o 4” brick C=1.25, R=1/1.25=0.8<br />
o 1/8” mineral board K=0.29, R=1/0.29 x 0.125=0.431<br />
o Total R = Rbrick + Rmineral = 0.8 + 0.431 = 1.231<br />
Total R is greater than 1.0, the system is acceptable.
