High Temperature …

High temperature ferritic stainless steels have broadly the same mechanical properties as their austenitic counterparts at room temperature. However, when subjected to high temperatures (> 600°C), it is possible for the creep strength to drop to just a quarter of the value an austenitic heat resistant steel would show in the same environment.

Underfloor heating plates are used in an underfloor heating system where polystyrene will establish an insulating layer directly on the levelled sand layer. For example, lay out a layer of polystyrene that is 250 mm thick. On top of this, lay out a vapour barrier and a layer of 50 x 50 mm joists at 60 cm intervals.

16. DETERMINATION OF THERMAL CONDUCTIVITY

Thermal conductivity λ is defined as ability of material to transmit heat and it is measured in watts per square metre of surface area for a temperature gradient of 1 K per unit thickness of 1 m. The thermal conductivity is not always constant. The main factors affected the thermal conductivity are the density of material, moisture of material and aient temperature.
