The CIM 500 Isolation Membrane kit from Daltile is a comprehensive system designed to provide crack isolation and sound reduction for tile installations. It typically includes all the necessary components for proper installation, such as the isolation membrane itself, adhesive, primer, and sometimes a roller for application. The isolation membrane helps prevent cracks in the substrate from transferring to the tile above, ensuring the longevity and durability of the tile installation. Additionally, it may offer sound reduction properties, improving the acoustics of the room. These kits are commonly used in both residential and commercial tile installations to ensure a high-quality and long-lasting result.
