what is thermal insulation

Thermal insulation is a crucial aspect of modern building and design, aimed at reducing heat transfer between different parts of a building. The goal is to improve heating and cooling efficiency, reduce energy costs and increase occupant comfort.

Thermal insulation works by using materials that have low thermal conductivity, meaning they hinder the transfer of heat by conduction, convection and radiation. These materials can range from traditional options such as glass wool and polystyrene foam to more advanced materials such as reflective films and vacuum insulation panels.
