BACKING ROD 20MM is a closed-cell polyethylene foam rod used as a backing material in expansion joints before applying sealants. It provides proper joint depth control, improves sealant performance, and prevents excessive material consumption. Ideal for construction, glazing, and waterproofing applications.
BACKING ROD 20MM is a flexible, closed-cell polyethylene foam filler used in construction and sealing applications to support sealant installation in expansion joints, gaps, and connection seams. It is designed to be inserted into joints before applying silicone, polyurethane, or other sealants.
The primary function of the backing rod is to control sealant depth, ensuring proper joint geometry for optimal adhesion and flexibility. By acting as a non-adhering base, it prevents sealant from bonding to the bottom of the joint, allowing it to perform effectively under movement and thermal expansion conditions.
Made from lightweight closed-cell foam, the backing rod is resistant to moisture absorption and does not react with most sealant materials. It is widely used in concrete joints, curtain wall systems, precast panels, glazing applications, and general construction sealing works.
The 20mm diameter size is suitable for medium-width joints commonly found in structural and architectural applications. It is easy to cut, compress, and install, making it a practical solution for contractors and waterproofing professionals.
