Metroforms combines Attraxion magnetic technology with the 38 colors of Metroflor LVT - Déjà New in 10 different patterns and geometric shapes. Thus, allowing for endless possibilities in pattern, shape, and color. Designed for compatibility with MagneBuild underlayment, Metroforms allows for easy, quick, glueless installations without locking systems. The MagneBuild underlayment (sold separately) adheres to an integrated ferrite (iron) film which is laminated to the bottom of Metroforms products. By merely rolling out the underlayment over almost any smooth, clean and dry subfloor, the flooring can be installed more easily and quickly than via any other method. The technology eliminates adhesive-related VOC’s and can reduce labor and removal costs. Metroforms is phthalate and formaldehyde-free, made with a 2.5 mm gauge, 0.5 mm (20 mil) wear layer, and includes FX3 Surface Protectant™. The product is covered by a 15-year commercial / lifetime residential limited warranty.
