Oak Natural Unsealed 240 x 20 mm

Engineered Flooring 240 mm x 20 mm

The versatile nature of Oak means this floor is perfect for all kinds of design scheme. From more traditional, natural looking styles to more contemporary, coloured finishes, Oak can be tailored to your preference.

Our engineered wood flooring meets modern requirements and keeps a traditional wood flooring appearance. The multiple layers of plywood backing give support to the visible top layer of the precious oak hardwood, resulting in a floor that looks and feels like a solid oak floor but that can be laid over almost all types of sub floor, and can still be sanded and re-finished after years of use.

Advances in engineered flooring technology means that boards can now be longer and wider than ever. Our 300 mm Engineered Oak board is the widest in the range but if that’s too large for your needs, why not consider a slightly narrower 240 mm or 210 mm board.

Unsealed products provide the flexibility to finish the wood in any colour once the floor is fitted. This gives you the option to have a completely bespoke floor, tailored to your personal preference.
We recommend adding 7-10% m2 to the total area for board or strip floors, or 10-15% for parquet.
