| Backer Rod is used for Chinking
log home joints greater than 1/4". Backer Rod is a round, flexible length of
extruded polyethylene (it looks like a foam rope). Backer Rod is
used to create a surface backing for the chinking. At the same time, Backer Rod
insulates and saves on the amount of chinking material being used. But most
important, Backer Rod acts as a bond breaker allowing the chinking to
adhere only to the top and bottom of the logs, not to the backer rod.
This allows the chinking to flex naturally as the logs shrink, instead
of peeling away. Spray adhesives may be needed when installing Closed
Cell Backer Rod.
