Closed-Cell Round Backer Rod is the product you need prior to chinking or caulking your log home. It not only acts as insulation but repels moisture, too. The closed-Cell Round Backer rod also serves as a bond-breaker between two logs and provides a structure against which you can apply chinking and caulk more uniformly in order to achieve an ideal joint.

Grip Strip is a closed-cell trapezoid-shaped product that, under normal use will not cause blisters in chinking material. The unique design provides an excellent fit with a flat surface within chink joint, resulting in saving on chinking. Can be used on exterior or interior surfaces.

Sealants and chinking do not adhere to the backer rod – only to the log surfaces of the joint – allowing for movement without damaging the sealing material.
