By definition, a backer rod is a lengthy cylindrical material that acts as a filler or pre-filler. Often used as backing (hence the name backer rods) for concrete panels before the application of caulking. It is synonymous in construction materials, as it is used in a wide variety of construction applications.

What are the typical uses of backer rods?

1.       Doors: It provides a more stable gap filler to secure door frames.

2.       Wall joints: By being placed in wall joints, a backer rod can act as a stabilizer by giving better rigidity.

3.       Windows: Provides better insulation and stability, giving a higher quality installation to window frames.
