It's very hard to find an attractive, affordable locking hardwood floor, especially one thats American made, so we have searched far and wide to bring one to the market. We now have the American made, FSC certified floating floor, True Hardwoods Northern Collection with TRUE HARDLOCK Technology. With the GreenCore technology, the plys are made of recycled hardwood. It's a beautiful 3/8" thick, 5" wide northern oak appearing in six appealing colors with a 1.7 mm face wear layer. The Northern Collection comes with a 25 year warranty, and a No-Gap Warranty. The locking system is so reliable, it's not affected by settled slabs or memory glue. Check out the colors below and call us for a free sample.
