The numerous types of thermal insulating materials, factors
that effect thermal insulation, and techniques to measure thermal conductivity
are all covered in the current study. In buildings, air conditioning systems
use the majority of the energy. Energy conservation is the primary factor that
underlies thermal insulation. Because it helps to significantly lower the
building's energy consumption, the study of the thermal performance of the
structure is essential for offering excellent comfort to the occupants. The
materials included include recycled organic waste products like bagasse, paper,
corncob, coconut fibre, and coconut shell as well as non-biodegradable products
like plastics and synthetic rubber. Natural materials covered include air, wood
fibres, sheep wool, leaves, and coconut fibre. These materials' thermal
conductivity ranges from 0 to 205 W/moK. Different techniques, including the
Guarded Hot Plate method, the Heat Flow method, the Hotwire method, the Laser
flash method, etc. can be used to measure thermal conductivity. Also addressed
are these techniques. The benefits of using a by-product are its simplicity,
little negative effects on health, and energy-efficient manufacture. Utilizing
recovered garbage is quicker and less expensive. All techniques for determining
thermal conductivity have benefits and drawbacks, as a result, a practical,
efficient, affordable, and time-consuming technique must be selected.
