The Backer Rod by United Insulations Co is a closed-cell polyethylene foam joint filler specially engineered for concrete and construction projects across Saudi Arabia. It acts as a reliable backing material that controls the sealant depth, prevents excessive sealant use, and ensures strong adhesion in all expansion and construction joints.
Manufactured to the highest international standards, this polyethylene expansion joint filler is lightweight, flexible, and resistant to moisture and chemicals — making it the perfect choice for high-performance sealing applications in commercial, residential, and industrial environments.
United Insulations Co’s Backer Rod enhances the long-term performance of sealants and extends the lifespan of construction joints by maintaining elasticity and preventing joint cracking or water ingress.
Its closed-cell technology ensures long-term stability and consistent insulation quality, even under extreme temperature changes.
