Matéflex modular flooring has added a stripflooring option to its line of vinyl floor tiles. The 4-by-36-by-1/2 inch PlankFlex planks are designed to look like wood flooring and have interlocking modular bases that snap together. One big selling point is that the planks can be installed over concrete—whether in a finished basement or a slab-on-grade home—without a subfloor. They come in five colors—oak, ash, cherry, chestnut, and gray— and cost $5.95 per plank.
