However, because marble tiles are usually twice as thick as ceramic tiles, they offer greater protection against thermal conductivity. Carpet, particularly wool and shag varieties, provides the best R-values among all standard flooring choices.

Thermal conductivity is a property of a material that determines the rate at which it can transfer heat. Each material's thermal conductivity is determined by a constant, λ, calculated as: λ = (Q x L) / (A x t x Δ T) where Q is heat, L is the thickness of the surface, A is the surface area, t is time, and ΔT is the difference in temperature.
The thermal conductivity of materials is required for the analysis of thermal resistance networks when studying heat transfer in a system. Please refer to the article " Thermal conductivity values for other metals and alloys " for further information.
The ratio between thermal and electrical conductivities of metals can be expressed in terms of the ratio: which may be called the Wiedemann-Franz Ratio or the Lorenz constant.
A toolbox of analytical relations is proposed to describe the effective thermal conductivity as a function of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction (ν p).
We are choosing between laminate and plastic flooring over water based underfloor heating (heat pipes laid in the screed floor over thick concrete). Laminate floorings have a thermal resistance of app. 0.06 m^2K/W, plastics (for example Classen NEO) have halve of that or less.
The velocity of thermal transfer for the laminated flooring used with the MPE foam was slower than the engineered flooring in which adhesive was used. However, the velocity of transfer was faster for the laminate flooring incorporating the PE foam.
The average thermal conductivity results are as follows: laminate flooring (0.115 W/mK) > solid-wood flooring (0.112 W/mK) > modified engineered flooring (0.111 W/mK) > engineered flooring (0.104 W/mK). The laminate and solid-wood flooring exhibit high density as they were made of HDF and thick solid wood.
This table shows thermal conductivity in SI units of watts per metre-kelvin (W·m −1 ·K −1). Some measurements use the imperial unit BTUs per foot per hour per degree Fahrenheit ( 1 BTU h −1 ft −1 F −1 = 1.728 W·m −1 ·K −1 ).

The choice of flooring material affects the heat up time, as each material has different thermal mass and conductivity. The lower thermal mass and higher the conductivity, the quicker the heat from an underfloor heating pipe or wire transfers onto the floor surface.
The thermal properties of water Description These experiments explore the thermal properties of water, including its boiling point, specific heat capacity and thermal conductivity.
Water does have thermal conductivity, however, it behaves in a convective manner the moment there are temperature differences in a volume. In practise, thermal conductivity will define how quickly heat is transferred to the liquid, adjacent to the heat source, but convection will dominate what happens to the heat next.
Furthermore, given that water is a good thermal insulator (due to its heat capacity), some frozen lakes might not completely thaw in summer. The layer of ice that floats on top insulates the water below. Water at about 4 °C (39 °F) also sinks to the bottom, thus keeping the temperature of the water at the bottom constant (see diagram).

Correspondingly, materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. The thermal conductivity of a material may depend on temperature.
