Backer rods are flexible, compressible foam rods used as backing material in joints or gaps before applying sealants. They help control the depth of the sealant, prevent three-sided adhesion, and provide a firm surface for tooling. Available in various diameters, they are essential in construction, glazing, and expansion joint applications.​Merz Construction+5EPE Foam Roller+5H-B+5EPE Foam Roller+2H-B+2FoamNet Plastic+2 �� Backer Rod Sizes and Applications Backer rods come in multiple diameters to suit different joint widths:​ 6mm to 15mm: Ideal for narrow joints in window frames, door perimeters, and small cracks in concrete. 20mm to 30mm: Suitable for medium-sized expansion joints in masonry walls and precast panels. 40mm to 50mm: Used for larger joints in infrastructure projects like highways, bridges, and large concrete slabs.​H-B+2EPE Foam Roller+2Merz Construction+2Merz Construction These rods are typically made from closed-cell polyethylene foam, offering benefits such as:​EPE Foam Roller+3H-B+3Merz Construction+3 Excellent compression and recovery properties.
