As radiant heating systems become standard in modern residential and commercial buildings, a common question arises: Is SPC flooring compatible with underfloor heating?

Due to its limestone-based core, SPC is not only compatible but is often considered one of the best materials for this application.

Why SPC Excels in Thermal Conductivity

Unlike wood, which acts as an insulator and slows down heat transfer, SPC (Stone Plastic Composite) is highly conductive.

The stone powder in the core allows heat to pass through the plank efficiently and evenly, warming the room faster and reducing energy consumption for the heating system.

Dimensional Stability Under Heat

Traditional vinyl (LVT) or WPC can soften or expand when exposed to high temperatures.

However, Senoinfi SPC Flooring is engineered for high dimensional stability. It maintains its shape and locking integrity even when the subfloor temperature fluctuates.

Crucial Installation Guidelines for Radiant Heat

To ensure a successful installation over a heating system, the following technical protocols must be observed:

• Subfloor Temperature: The surface temperature of the subfloor should never exceed $27°C$ ($80°F$).

• System Type: SPC is compatible with both hydronic (water-based) and electric radiant heat systems, provided they are embedded in the subfloor.

• Acclimatization: Planks should be acclimated in the room for at least 48 hours before installation.

• Expansion Gaps: Ensure a minimum gap of 8mm-10mm around the perimeter to allow for natural movement.
