Why dont you supply Solid Oak wider than 150mm?
In our opinion, anything wider than 150mm in Solid is more likely to cup or distort after installation. After all, it is a natural product and always wants to move or soak up any excess moisture. Not only that but anything wider than 150mm we advise face-fixing, which involves much more work and becomes more expensive and time-consuming to fit. If you want a wider board, just look at our Engineered Oak. It looks like Solid when fitted but behaves itself a lot better! The 21mm Engineered will also give you as much lifespan as an 18mm solid oak.
