Backer Materials that Seal Things Right the First Time.
Backer Rod, Grip Strip, and Log Gap Cap all help you create the ideal joint design for a long-lasting, durable seal.
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.

Description
Closed Cell 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.
Closed cell backer rod is probably the most common form of backer rod. It does not hold moisture and actually repels water. Closed cell backer rod comes in a variety of sizes ranging from 1/4″ to 5” wide and can be used on both the exterior and interior of the home.
Round backer rod can be used in almost every joint style except flat Applachian style logs. The round nature of the backer rod allows the caulking / chinking to adhere well to the wood, while the slightly thinner layer in the center allows the material to move with the logs. This also makes it so that any failure due to extreme movement will generally split down the middle of the bead line, allowing for an easy fix.
