Backing Rod
Backing Rod is an essential component in roofing projects, providing crucial support and improving the longevity of sealants. It is a cylindrical, flexible foam rod inserted into joints and cracks before applying sealants, ensuring a perfect fit and maximum effectiveness. The primary function of Backing Rod is to control the depth of the sealant and create an optimal shape for joint movement, therefore enhancing the sealant’s performance and durability.
In roofing applications, Backing Rod serves as a reliable backing material for various sealants, including polyurethane, silicone, and acrylic. Its use is particularly beneficial in expansion joints, perimeter joints, and any areas where differential movement is expected. By filling the voids and reducing the amount of sealant needed, Backing Rod not only ensures a stronger seal but also results in cost savings.
Made from closed-cell polyethylene or open-cell polyurethane foam, Backing Rod is available in different diameters to suit various joint widths. Closed-cell Backing Rod is waterproof and resistant to moisture, making it ideal for exterior roofing applications where water exposure is a concern. Open-cell Backing Rod, on the other hand, is more compressible and suitable for interior joints where moisture is less of an issue.
Using Backing Rod in roofing projects simplifies the sealing process, prevents three-sided adhesion, and allows for the sealant to adhere only to the sides of the joint. If you are looking for backing rod, browse our range of backing rod options available via our website.
