Description
The Invisible Seal Oak Plank delivers the look of unfinished oak with the protection of a UV oil finish. Designed to keep the wood’s natural tones intact, the invisible seal allows the grain and colour to shine through as if the boards were raw, while still guarding against everyday wear.
At an impressive 300mm wide and 2200mm in length, these planks create a striking, expansive feel that instantly elevates larger interiors. The Rustic grade oak showcases knots, tonal shifts, and grain variation, ensuring every floor has authentic character and individuality.
With a substantial 20mm profile and a 6mm wear layer, this engineered flooring is built to last, offering the option to sand and refinish multiple times across its life. The tongue and groove system provides a secure installation, while micro-bevelled edges give definition to the extra-wide format.
Fully suitable for underfloor heating and backed by a 25-year warranty, the Invisible Seal Oak Plank combines the natural look of unfinished oak with the practical benefits of an oiled surface — a premium choice for contemporary, design-led spaces.
