Gypsol Screed Thermoplane

Thinner minimum depth/Higher conductivity. Thermoplane has a significantly higher thermal conductivity than sand cement screeds and tier, coupled with its self compacting ability which eliminates air entrapment and thinner overall screed depth, (Minimum 25mm nominal 30mm cover to the pipes) leads to a more energy efficient and responsive screed.

Thermal conductivity of concrete – A review ScienceDirect

The thermal conductivity (k-value) of cement-based materials like concrete is an important factor when considering the amount of heat transfer through conduction. The amount of heat loss through walls and roofs has a direct effect on the energy consumption of buildings. The steady state and transient methods are considered the two main thermal
