The Knot Carpet family was created in 2011. At that time, Pinnacle was a proprietary blend of fibers composed of recycled plastic bottles and an Ecore backing. The result: a carpet designed for the most abusive commercial, industrial, and retail applications. In 2015, this product evolved to include a new and improved soft surface, which is able to withstand the same abuse. The interlocking tile format offers a simple, adhesive-free installation. Pinnacle 2 features Ecore's patented itstru technology, where carpet is fusion bonded to an Ecore 90 percent recycled rubber backing. The result: a product that provides a prescription for comfort and superior performance characteristics.
