GemCore Emerald Crawford combines the natural look of wood with the stability and waterproof performance of GemCore stone-composite flooring. Built for residential and light-commercial interiors, the Emerald Collection uses a dense rigid core made with more than 70% stone to improve dimensional stability and resistance to dents, heat and moisture compared with traditional flexible vinyl flooring.

Crawford features a high-definition wood décor layer protected by a quartz-enhanced acrylic coating and a 12 mil wear layer. The 7" × 48.6" planks are 4 mm overall, including a factory-attached 1 mm anti-microbial EVA foam pad. Each carton contains 13 planks and covers 30.76 sq. ft.

Emerald installs as a floating glueless tap-down floor using the i4F locking system or may be glue-down installed where appropriate. The collection is approved for use with under-floor heating when installed in accordance with the manufacturer instructions. Emerald is backed by a lifetime residential and 5-year light-commercial warranty in the collection technical literature.
