Radiant Heat Installations
The following guidelines must be followed to maintain warranty coverage. Failure to follow ALL guidelines will
result in termination of warranty coverage.
• Concrete must be allowed to properly cure and dry a minimum of 4 weeks prior to operation of radiant heat
system.
• Over concrete, moisture vapor emission rate for concrete subfloors must not exceed 3 pounds per 1000 sf per
24 hours using Calcium Chloride test ASTM 1869, or 75% RH using ASTM 2170k and must be documented for
warranty coverage.
• Wood subfloors must not exceed 12% moisture content and be within 2% moisture content as that of the
BSPC flooring.
• Subfloor must be flat to 3/16” over a 10’ radius or 1/8” over a 6’ radius.
• T-moldings must be used to separate heating zones.
• The use of a separate thermostat for each individual zone is required. An outdoor temperature sensor is highly
recommended to adjust temperature according to anticipated heat loss.
• Operation of radiant heat system should be set to run at 2/3 of the maximum output for a minimum of 2
weeks prior to installation of flooring to further allow moisture from concrete to dissipate and reach a final
moisture content. This must be done in both heating AND non-heating seasons.
• Reduce heat to a temperature of 65° 4 days prior to installation.
• Floating Installation - Install flooring according to floating floor installation guidelines. We require the use of a
6mil poly-film in conjunction with underlayment.
• After 48 hours post-installation, we recommend to slowly raise temperature of the heating system to its
preferred operating level. Please exercise caution and expect to achieve peak after a period of 5 days.
• Do not allow the subfloor surface temperature to exceed 80°F with no more than a 5◦F variance in surface
temperature over a 24-hour period.
• Relative humidity of the jobsite must be maintained between 35-55% relative humidity. The use of a
humidification/dehumidification system may be required to maintain the proper humidity level. Failure to
maintain proper humidity level can result in excessive dryness of flooring and void the warranty.
• Seasonal expansion and contraction is expected and does not mean a defect is present within the product.
GENERAL INSTALLATION TOOLS
• Moisture Meter
• Tape Measure
• Pencil
• Chalk Line
• Hand Saw or Power Saw
• Utility Knife
• Tapping block
• Crow Bar or Pry Bar
• Wood or Plastic Spacers (¼”)
• Hammer or Rubber Mallet
FOR FLOATING INSTALLATION, YOU WILL ALSO NEED:
• 6mil poly-film moisture barrier
• Underlayment
FOR GLUE-DOWN INSTALLATION, YOU WILL ALSO NEED:
• Premium Pressure Sensitive Vinyl Flooring Adhesive
• Adhesive trowel (as recommended by adhesive manufacturer)
