This floor is not recommended for a glue down application and we do not we recommend any solid floors over radiant heat.
Lumber Liquidators recommends floating floors -flooring not attached to the subfloor- for radiant heat applications. To ensure performance, the consumer should be aware of risks associated with nailing or gluing solid wood over radiant heat and ensure product selection and installation practices are appropriate for the application. If you choose to use solid wood, select quarter-sawn or rift-sawn materials. Note that even using solid wood species with known positive dimensional *stability characteristics than others, cannot predictably be guaranteed to perform well in every application. In addition, radiant systems if not monitored and controlled properly can negatively impact the long term finish performance of wood flooring and may result in finish chipping, peeling or hazy finish.
Here are the recommended choices for in-floor heating:
Floating floors - Most recommended because these types of floorings are installed over an underlayment and not attached or fixed to the subfloor. The flooring is free to move as a total unit to better accommodate subfloor movement and environmental fluctuations (moisture and temperature).
Engineered flooring –Works well over radiant heat because its unique plywood construction creates greater stability as each wood layer is positioned perpendicular to the other thereby resisting movement from environmental fluctuations (Depending on the selection can be nailed, glued or floated over the subflooring). If choosing engineered flooring for a radiant heat application, the consumer is advised to select a product constructed using a relatively stable wood species on the top surface. Consult your local Lumber Liquidators store or customer care for assistance if needed.
Quarter-sawn or rift-sawn – This cut or style of solid wood flooring is most preferable because it tends to expand more upwards in the direction of the grain with less side to side movement common with plain-sawn cut flooring. In addition, quarter-sawn solid flooring reduces the likelihood of side gapping and board edge cupping due to environmental fluctuations.
Strip flooring; boards 3” wide and less – Selecting a flooring product in a width measuring 3” or less is a better choice than planks or wider flooring because narrow boards will allow more board movement and will expand and contract less under varying environmental conditions when compared to wider boards. As a general rule, wider boards can have wider side or seam gaps.
