In [12], we have investigated heat transfer model, conduction heat and radiation heat and Considered the effect of the ,thickness, of the ,layers, on different heat conditions.

Top 4 Best Insulation for interior walls of 2019
Top 4 Best Insulation for interior walls of 2019

The ,thickness, of the ,insulation,: Greater the ,thickness, of the ,insulation,, better will be the effectiveness. Therefore one should keep the ,insulation thickness, between 10mm to 100mm. Moisture resistance: Depending on the amount of moisture a wall will have to face, one can choose a material which is either hydrophobic or hygroscopic.

Thermal Insulation Heat and Thermodynamics
Thermal Insulation Heat and Thermodynamics

The R-value is proportional to the ,thickness, of the material. For example, if you doubled the ,thickness,, the R-value doubles. In conclusion. ,Thermal insulation, is used minimize the heat transfer in many everyday situations. It is done by reducing conduction, convection and/or radiation effects.
