Twickenham Solid Golden Oak Lacquered & Handscraped 125mm X 18mm Wood Flooring A classic golden oak handscraped, which has been finished to create a wavy effect to each plank. This natural product will show some knots, as is common with an oak product. The plank width is 125mm with a total plank thickness of 18mm. The installation system on this product is tongue and groove, which would usually be fitted by gluing the planks together and using the glue down method to fix the boards to the sub-floor. #solidwood #oakflooring #woodfloor #flooringexperts #flooring
