Galleria Elite Fumed Oak 150mm Oiled Engineered Flooring offers a beautiful, richly-coloured surface with a wide range of rustic grade features, giving it an aged look. Among the elements making up the rustic grade are various lines, rings, knots, variations in shade & mineral streaks. The visual impact is added to by the application of UV oil, which blends in & brings out the full colour & character of the grain. All four sides of each plank have bevelled edges, with these v-grooves giving the floor extra depth & dimension. In addition to its attractive appearance, the product also has a high level of stability with 11 layers of wood combined, which also gives it great protection against denting. The 4 mm hardwood layer on top can be sanded up to six times, but with good care & maintenance this should not be required for the first 20 years. Galleria Engineered Structural Fumed Oak 150mm Oiled Flooring wide, has a total thickness of 18mm & comes in random lengths of between 500mm-1700mm, with an average length of 900mm.
