Introduction to Thermal Insulation for Energy Efficient Buildings

The video tutorial discusses how to reduce energy loss in buildings by using thermal insulation techniques. It explains the concept of thermal insulators and their properties, focusing on thermal conductivity. The tutorial compares different materials like bricks, hardwoods, and insulation based on their thermal conductivity. It also covers methods like double glazing and cavity walls to minimize unwanted energy transfers. An experiment is conducted to test the effectiveness of various insulation materials, highlighting wool as the best insulator among those tested.

Describe the setup of a cavity wall and its purpose in energy transfer reduction.

What were the four types of insulation tested in the experiment?

Which insulation material was found to be the best in retaining thermal energy, and why?
