The Summit Collection is a range 10 colors with a 7mm thick core and a board length of 1820mm. It is for those who need extra height or prefer the feel of a thicker board and like a long board appearance. 7mm is an extra heavy duty core but combined with our proprietary formula, the co-extrusion blend is one of the most dense compounds used in flooring anywhere in the world. 7mm is only the core thickness, not the total board thickness. It is the core that gives every board its inherent abilities to remain unaffected by wet conditions (under normal use circumstances). High Definition Scanning and printing combined with embossing (texturing) which we have taken directly from real world timber products, results in a floorboard that you will struggle to distinguish from a real wooden product.
