The reason for this is that boards of this thickness will allow the heat to pass into the room more efficiently than a thicker board.
Timber floor thickness.
An engineered wood floor which is being fitted over under floor heating is normally recommended to be a maximum of 15mm thick.

Standard hardwood flooring planks are 3 4 inch thick 2 1 4 inches wide and sold n various lengths from 12 to 84 inches.
1 2 inch 12 7 mm 5 8 inch 15 88 mm.
Joists that sit below end matched joints must be at least 35mm thick.
When choosing the thickness of engineered wood flooring there are two different considerations to be taken into account.
For joists spaced more than 19 2 inches on center the minimum thickness for plywood is 7 8 inch and for osb 1 inch.
The first is the thickness of the overall board and the second is the thickness of the solid wood lamella or top layer.
Where the existing floor is structurally sound either overlay flooring generally 11 mm to 14 mm thick or structural flooring generally 19 mm to 21 mm thick can be laid.
The joists can be longer or shorter as required by space and size and are typically spaced at either 450mm or 600mm apart.
For joist spacing of more than 16 inches up to 19 2 inches on center the minimum thickness for both plywood and osb is 3 4 inch.
What is the level of traffic your floor will need to stand.
