Such wood species as birch, oak, red oak, ash, European walnut, American cherry, doussie, kambala, merbau, sapelle and wenge can be laid over a floor heating system.
The Baltic Wood three-layer hardwood flooring can be laid on floor heating. In such a case, we recommend that the floor be glued to the base, since that ensures a more effective heat transfer from the heating system into the interior.

The wood species that CAN NOT be laid over floor heating are beech, steamed beech, European and Canadian maple, badi, jatoba and tali.
