Backer Rod: Uses and Applications

August 31, 2018

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


A backer rod is a useful piece of equipment that has a number of applications in the construction industry.


By providing support and assisting in the sealing process in between gaps or joints on a construction basis, backer rods have proven to be essential. Below are some examples of the typical uses of a backer rod:


1.       Doors – Backer rods provide a more stable gap filler to secure door frames.


2.       Wall Joints – Being of different material in-between walls, it can act as a stabilizer giving better rigidity.


3.       Windows – A backer rod offers better insulation and stability which provides a higher quality installation to window frames and other similar situations.


4.       Flooring – Acting as an insulated divider or joiner between concrete sections, backer rods also minimize the amount of caulking used and gives a better absorbing foundation to sudden movements.
