Introduction
Backer Rod Incorrectly Fixed
Type of Building: Commercial Building
In this case, the backer rod in the joint between the panels are already started to dislodge. This will affect the performance of the façade as water will be able to penetrate to the backing wall.
Backer rods are compressible, rod-shaped materials used in construction to support sealants and caulks in joints, gaps, voids, grooves, and cracks. Available in various sizes, shapes, and foam structures, they are typically installed before sealants to ensure proper placement, reduce waste, and enhance the effectiveness of the seal.
