Can I lay cork over underfloor heating?
The factor that decides whether flooring is suitable for use with underfloor heating is its ability to conduct heat. Both cork parquet and “glueless” floating parquet are safely below the recommended limit of 0.17 m2K/W. With 0.3m2K/W, “glueless” floating cork parquet is well suited for use with underfloor heating. To ensure good heat transfer between the heated screed and the floating cork parquet, the subfloor should be as level as possible. In the case of 4mm thick cork parquet, the resistance to heat conduction is even lower (0.05m2K/W). This makes this flooring ideal for warm-water underfloor heating. Use with other types of floor heating, however, is not possible. The surface temperature of the heated screed should not exceed 28C. If underfloor heating is used, air humidity is greater nearer the floor. We therefore recommend adjusting the air humidity while the heating is in operation.
