Warmboard is uniquely suited for use with all types of finished floors. With over 25 million square feet installed around the world, Warmboard has a proven track record of success when used with hardwood, tile, stone, carpet and any other type of finished floor.
All finished floors attach to Warmboard in generally the same way they attach to standard subfloor. When it comes to installing strip or plank hardwood over Warmboard, there are only a couple of key factors to be aware of. First, because of the natural properties associated with the aluminum on every Warmboard panel, no additional vapor retarder is required. This simplifies and quickens the installation process while reducing the need for additional parts and labor
Secondly, the tubing must be avoided when nailing. This is an easy task however since the tubing can be clearly seen at all times. This often is not the case with other radiant systems.
Warmboard Inc., like other plywood and OSB panel manufacturers, recommends you follow all installation specifications documented by the NWFA (National Wood Flooring Association).
In addition to plank or strip flooring, there are other types of wood floors that will also interface nicely with Warmboard, including:
- Engineered hardwood
- Laminate hardwood
There are four standard methods of installation of that we do approve and endorse:
- Nail down only
- Glue and nail
- Glue down only
- Floating floor with acoustic mat.
We recommend that any method you choose is also approved by the hardwood manufacturer. To review a list of hardwood manufacturers who have recommended Warmboard, review our Install Guide.
We also have several warranty letters from manufacturers for hardwood and tiling applications. For a copy of any of these letters, please give us a call.

When the radiant floor system is operating, the surface temperature of the finish floor should not exceed 85 degrees Fahrenheit. This is an industry standard to protect the hardwood. It is important to relay this information to General Contractor and Heating Contractor. Surface temperatures will be determined by the water temperatures that circulate though the tubing. In general, water temperatures should not exceed 110–120 degrees Fahrenheit, depending on the R-value of the finish floor.
