How to fill the gap between hearth and floating engineer floor?

[carpet_the_walls]

I want to fill the gap between a slate hearth, and a floating engineered oak wooden floor.

We have a wood burner, and ash has a tendency to find its way into the gap.

How should the gap be filled please?

Thanks

I built a wood frame that sits tight to the hearth and on top of the surrounding floor. Frames the hearth nicely.

Hope you have left a big expansion gap on the walls as that wood is to close to the fireplace. You should cut it back 30mm then put a solid oak T bar doortrim in
