The maximum thermal performance or R-value of insulation is very dependent on proper installation. Homeowners can install some types of insulation -- notably blankets and materials that can be poured in place.

It is strong and rigid and, unlike high temperature plastics, will ... POLYSULFONE is an amorphous high performance polymer characterized by excellent thermal properties, good resistance to ...
Butane - Thermal Conductivity - Online calculators, figures and tables showing thermal conductivity of liquid and gaseous butane, C 4 H 10, at varying temperarure and pressure, SI and Imperial units Conductive Heat Transfer - Heat transfer takes place as conduction in a soilid if there is a temperature gradient
The problem with the thermal conductivity of ceramics is the dependence on the composition, grain size, and manufacturing process, which make it rather difficult to obtain a reliable value from literature only.
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.

Whereas unfilled thermoplastics have a thermal conductivity of around 0.2 W/mK (Watts/meter-°Kelvin), most thermally conductive plastic compounds typically have 10 to 50 times higher conductivity (1-10 W/mK). One firm, Cool Polymers, offers products with 100 to 500 times the conductivity of a base polymer (10-100 W/mK).

Thermal conductivity - use long term value i.e. that expected to be achieved over the expected building life span (25 years) as design value - refer back to insulation suppliers.
Thermal Resistance. The R-value (thermal resistance) of a building material is its resistance to the flow of heat.As explained in the preceding subsection, the R-value is the reciprocal of the k-value or the C-value and rep- resents heat flow resistance expressed as a numerical value.The higher the R-value of a material (or a combination of materials in a wall, ceiling, floor, or roof), the ...
Due to its low weight and high impact resistance, polycarbonate is the dominant material for making automotive headlamp lenses. However, automotive headlamps require outer surface coatings because of its low scratch resistance and susceptibility to ultraviolet degradation (yellowing).
The U-factor is the heat transfer coefficient, which simply means that is is a measure of an assembly's capacity to transfer thermal energy across its thickness. The U-factor of an assembly is the reciprocal of the total R-value of the assembly.
