Thermal resistance, or the R-value, quantifies the insulation properties of luxury vinyl planks. When using LVP over radiant heat, installers must check the manufacturer's maximum allowable temperature, usually capped around 85 degrees Fahrenheit (29 degrees Celsius). Higher thermal resistance may insulate too much, potentially trapping heat and affecting the floor's structural integrity. Testing methods ensure the material remains stable under fluctuating thermal loads without exceeding limits that could compromise locking joints or plank adhesives.

How is thermal resistance measured in LVP?
Thermal resistance in LVP is typically measured by its R-value, indicating how well the material resists heat flow. This rating is crucial for compatibility with underfloor heating systems, ensuring the flooring does not warp or degrade when exposed to consistent elevated temperatures.
