Ecore's 6 mm x 2-1/2 in. x 50 ft. QT Perimeter Isolation Strip is engineered from durable recycled rubber to maintain consistent compression resistance and long-term dimensional stability under floor loading. Its flexible strip design allows for easy installation around room perimeters while maintaining continuous acoustic separation between flooring systems and structural walls. Developed for compatibility with resilient flooring solutions from Ecore International, it enhances overall sound isolation performance by minimizing flanking noise paths and reinforcing the effectiveness of full-floor acoustic assemblies.
