Fire Retardant Rigid Cavity Closer System

Example of Thermal Resistance for Type-R Fire Stop Check Reveal

This table shows the thermal resistance for each segment of the path ABC. The thermal resistance for each segment is obtained by dividing the length of the path segment in metres by its thermal conductivity in W/mK.

Path Segment	Length (m)	Conductivity (W/mK)	Resistance (m:²K/W)
A - B	0.0275	0.12	0.23
B - C	0.065	0.034	1.192
Thermal Resistance Path (‘R’value) = 2.142m:²K/W
