Profile: Schroeder Log Home Supply, Inc. specializes in offering backer rod, caulking, chinking, log home finishes, fasteners, sealant tapes, tools, wood treatments, & restoration products for log homes, youth camps, resorts, historic wooden structures and wood sided buildings. Backer rod is used for chinking log home joints greater than 1/4 inches. It is a round, flexible length of extruded polyethylene and is used to create a surface backing for the chinking. It insulates and saves on the amount of chinking material being used.It 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. Our fasteners include joist hangers, log screws, spikes, post pal and log splines.
