Backer Rod

Ozark Log Home Supply
Backer Rod is a foam material used to fill large checks and gaps between logs. It also provides support for chinking and sealants. Its primary purpose is act as a "bond-breaker" and promote two-point adhesion (see diagram), giving the joint and sealing material the ability to compress and expand as logs move. 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. Sashco distributes a number of types and profiles of backer rod including the unique Grip Strip™. You should select backer rod based upon your particular needs. Open-cell type is recommended to speed drying. A closed-cell type is more moisture resistant. (Ask your applicator or contact Sashco for a handy comparison sheet.)
