Radiant Heat Guidelines and Conditions
Aspen Flooring Euro Oak and Walnut hardwood is warranted over radiant heat. Maple and
Hickory are not warranted over radiant heat.
To install any of our flooring products over radiant heat, the following procedures and information
should be followed for best results:
Only Aspen Hardwood Flooring products, greater than 1⁄2” thickness are approved for installation over
radiant heated subfloors using Adhered installation methods for the product. We do not warranty our 5.5
or 6 mm wear layer over radiant heat installation. Hickory or Maple engineered in any width or thickness
is not recommended for installation over radiant heat installation.
• Nail or Staple Down installation methods are not recommended for Radiant Heated Sub Floors.
• Radiant Heating Systems used must be designed and controlled specifically for Hardwood flooring by
the system manufacturer, and include an Outside Temperature Probe, and Surface Temperature Controls.
• The end consumer should be aware that minor gapping between wood planks during the heating season
is a normal occurrence with hardwood flooring installed over radiant heated subfloors.
• Proper humidity controls within the home or business will help to minimize the natural wood reaction
to seasonally changing climate conditions.
• Indoor climate should be maintained between 60-80° F and a relative humidity range of 35%-65%.
Adhere to the following for a successful Radiant Heat installation:
• Newly installed hydronic type radiant heated flooring systems should be in operational mode with the
temperature set between 64° -72°F, for a minimum of 4 weeks to insure that all sub floor moisture has
properly dried.
• Older water type radiant floor heat systems should be fully pressure tested, properly maintained, and set
to a minimum of 64°F, for at least 6 days before flooring delivery; acclimation, or installation processes
may begin.
• All radiant heating systems must be set to room temp. (A minimum of 64°F), for at least 6 days before
flooring delivery; acclimation, or installation processes may begin.
• Always check wood sub floors to insure that the moisture content is less than 12% using an accurate
wood moisture meter.
• Concrete sub floors must register “dry”, using approved quantitative concrete moisture meter.
• The pH level of concrete sub floors should register between 6 and 9, on a fourteen point pH scale.
• Sub floors must fully comply with these “dry” requirements before proceeding with the delivery,
acclimation, or installation of the wood flooring at the job site.
• Install the hardwood flooring according to the instructions that pertain to the product.
• After completing the installation, do not change the radiant heat setting for 48 hrs.
• Throughout the life of the installation, 3 to 5 degree daily increments must be used when adjusting
system temperature for either upward or lower adjustments; so that the hardwood flooring can adjust to
the temperature changes in a gradual manner.
• Never raise the flooring surface temperature setting above 85 degrees Fahrenheit.
• Regulate the job site to insure that the relative humidity is between 35% and 65%, and that temperature
is between 60° and 80° F, throughout the flooring delivery, acclimation, installation and any required
curing processes.
• Deliver and acclimate the engineered hardwood flooring, for at least 48 hours before installation begins.
