The Various Performance Factors in Thermal Insulation Materials

Materials of thermal insulation are a rapidly growing accessory in the overall structurisation of a building or a house. The importance and advantages of thermal insulation have adopted many technological additions to give homeowners the best life under controlled temperature. Especially for people who live in extreme weather conditions with inconsistent and harrowing weather interfering with their daily lives, thermal insulation is a constructional boon. For an ambient and sustainable home surrounding, it is indispensable to get a barrier installed to constrict harsh air currents or scorching hot waves to drastically decrease or increase indoor weather balance respectively. Apart from its intrinsic property as an efficient thermal barrier, insulation is an affordable option, if considered in the long run providing other advantages like mould protection, environmental sustainability, sound control, and more. As a result of these compiled benefits, thermal insulation is affordable and helps you contribute your share to global environmental maintenance.

Insulation is available in various types with each providing valuable benefits for specific insulation purposes and requirements. Also, some key factors are affecting the functional and performance quality of an insulation material that should always be considered before going forward with the installation. If you are looking to upgrade your home or office space with the functional benefits of insulation, the following factors will help you determine the best auxiliary for your living standards.

Thermal Conductivity

The efficiency with which heat travels through various materials is measured as its thermal conductivity rate. Conduction through an insulation material constitutes its thermal conductivity that is measured in the unit of lambda (λ). If you are looking for a high-performance thermal insulation material, always keep in mind that the lower the value of lambda, the better the performance of the material.

Thermal Resistance

Calculated as the quotient of the thickness of the width of the material as dividend and its conductivity as a divisor, resistance or R is integral in determining the overall performance of an insulator. A greater width of a material determines very less heat flow and as a result, a lower conductivity value. These parameters are integral in thermal insulation that helps in identifying the better material. Thus, if a construction or insulation material is chosen with a higher thermal resistance or R-value, it is inherently a good insulator. Conversely, a lower R-value means the material is not best suited as an insulator.

Specific Heat Capacity

The amount of heat required to increase the temperature of 1 kg of any material by 1K is its Specific Heat Capacity. If a material with higher SHC is invariably as good insulator as it will require more time to heat up by a degree before it can reach a temperature to act as a medium of heat transfer.

Thermal Diffusivity

Measured as the ability to conduct thermal energy against that of its storage capacity, thermal diffusivity is another factor in determining the performance factor of insulating material. Metals transfer energy faster than wood and hence, wood is a better insulator than metal. The lower the thermal diffusivity value, the better it is as an insulator.


Another important factor in determining the performance value of a material is density calculated as mass per unit volume. A material with higher density means the weight of the material is higher and hence, is low in thermal diffusivity and high in thermal mass.

Thermal Bridging

A thermal bridge is described as the area of a material that has higher thermal conductivity value than its surroundings and thus paving the path of lowered resistance for heat transfer. A thermal bridge is an important aspect in deducing down to which material works best as an insulator. The impact is so substantial that they can reduce the overall effectiveness of the insulating material. So before buying, always speak with your salesperson to choose the right one for your home.
