Nichiha's Single Flange Sealant Backer is compatible with Nichihas Architectural Wall Panel systems and integrates seamlessly with other trim components. At 6 feet 6 inches in length, it covers a significant span while minimizing the number of joints required across the wall assembly. This component plays a vital role in the building envelope, especially in areas where direct panel-to-substrate terminations aren't practical or desirable. It is commonly used in conjunction with sealant to absorb movement and prevent moisture intrusion.
