SOF® ROD is an open cell, polyethylene foam backer rod that is extruded to leave an impermeable shell that prevents moisture from entering the side. The advantage of SOF ROD is that it is very flexible and easy to install. Smaller sizes are offered to fit those really tight joints. When choosing a size, the diameter should be approximately 25% larger than the joint because of the compressibility. SOF ROD 1½" through 4" are in 6' lengths, smaller sizes are a continuous length. In smaller joints a blunt tool may be needed to push backer further into the joint to allow the required amount of chinking. SOF ROD backer rod is the easiest type of backer rod to work with for smaller size joints. Made in the USA. SOF ROD Technical Data | MSDS
SOF ROD Backer Rod makes a very effective and economical log sealant as a compression “tape” between log courses, due to its high compressibility and moisture repellent surface. The usual size for this type of application is between the 1â…›" and 2". Spray adhesive can be used to hold its position on the logs or it can be tacked by stapling along one side as well. It is especially popular with the double-scribed method of the Swedish Cope style of construction.
