Engineered Flooring Over Radiant Heat

Q: Are there any species of engineered hardwoods that should not be
used over radiant heat?
Thank you
A: Generally speaking you can use any species of engineered flooring when installing over radiant heat. Some species are more stable than others, but when using an engineered product it becomes less important about species. The key to making an engineered floor perform well over radiant heat systems is to ensure that the product has 5 or more plies along with quality construction which usually results in each ply being somewhat thicker.
Some manufacturers will suggest not to use a particular species (typically less stable species) over a radiant heat system because that species is too likely to expand and contract heavily due to heat changes. Always check with a manufacturer before putting any floor over a radiant heat system.
My other major piece of advice for you is to ensure you acclimate your floor well. I recommend acclimating for a week before installing your product.
