Which material has the lowest thermal conductivity?
A new generation of insulation materials, airgel. It is currently recognized as the lowest thermal conductivity of solid materials.Jul 12, 2017
What is the thermal conductivity of Pu insulation?
- Depending on the facings and thickness, PU can achieve a thermal conductivity as low as 0.022 W/m·K to 0.028 W/m·K. This makes it one of the most efficient insulation materials available on the market. When compared to other materials, a much lower thickness of PU insulation is needed to get the same level of performance.
What are the different types of construction insulation materials?
- Below we take a look at performances exhibited by a range of common and increasingly common construction insulation materials. Insulation materials, particularly where 'green' specification is concerned, divide into so-called 'natural' materials and 'man-made' materials.
Why does a good insulator have a higher specific heat capacity?
- A good insulator has a higher Specific Heat Capacity because it takes time to absorb more heat before it actually heats up (temperature rising) to transfer the heat. High Specific Heat Capacity is a feature of materials providing Thermal Mass or Thermal Buffering (Decrement Delay).

What are the basic requirements in thermal insulation materials?What are the basic requirements in thermal insulation materials?
The basic requirement in thermal insulation materials is to prevent heat transfer. The lower the thermal conductivity calculation value, λh, the better the thermal insulation performance of the material. The length, width, deviation from square and surface flatness of the thermal insulation material should be produced within specified tolerances.
What is the thermal conductivity of glass foam?What is the thermal conductivity of glass foam?
Glass foam obtained by melting powder glass together with carbon is a very hard, high compressive strength, easily broken, vapor-impermeable (μ = 10000) insulation material. Its thermal conductivity calculation value is λh = 0.045-0.060 W / mK, it is a non-combustible material with A1-A2 fire class.
