What is the purpose of thermal insulation?

The purpose of thermal insulation is to maintain temperature by reducing heat transfer. This is achieved through the use of materials that have high resistance to heat flow, which helps to keep interiors warm in the winter and cool in the summer. This effective regulation of temperature enhances energy efficiency by minimizing the need for heating and cooling systems, thus reducing energy costs and environmental impact. Proper thermal insulation contributes to a more comfortable living or working environment by preventing drafts and maintaining a consistent indoor climate, making it a critical component of building design.
