U-Value Kit for checking the Swiss room climate standard

The Swiss standard SIA 180 includes requirements for heat protection, damp-proofing and indoor climate in buildings. Amongst other necessities, it requires the use of a floor whose thermal storage capacity can be used. In a pilot project, building scientists were uncertain whether the application of an insulating flooring (for example, parquet, linoleum, etc.) would fail in complying with the limit values per SIA 180. Our U-Value Kit allows to simply and precisely check these conditions.

Measurements have shown that a flooring such as novilon / linoleum has no or only insignificant influence on the thermal performance of the floor (see diagram). In a test, the heat flux sensors of two U-Value Kits were positioned at two different locations on the floor of a building. Once on bare artificial stone flooring and once on novilon / linoleum, which was mounted on the artificial stone flooring (see sketch).
