The importance of Insulation of buildings

The educators should familiarize themselves with the concept of insulation and understand that all thermal insulation materials work on a single basic principle: heat moves from warmer to colder areas.

Therefore, on cold days, heat from inside a building seeks to get outside. And on warmer days, the heat from outside the building seeks to get inside. Insulation is the material which slows this process.

This lesson tests the insulation performance of different materials by comparing these in an experiment.

The educators should understand and prepare so they can engage in a discussion on the basic principles:

• heat transfer
• conduction
• convection
• radiation

the inhibitions of conduction, convection and radiation

The students will conduct an experiment to test insulation materials.

The test is based on comparing four bottles, wrapped in four different insulation materials and filled with boiling water. The temperature is measured after 10 and 15 minutes. The difference equates to the quality of the insulation wrapped around the bottle.

Image showing two bottles, left without isolation, right with isolation.

• Wrap 4 equal plastic bottles in insulation material. E.g. silver foil, paper, mineral wool, plastic bag, woolen sock
• Pour boiling water and close with cap
• wait 15 minutes.
• Measure temperature in the four bottles
• Map temperatures to time in graph: time on X-axis and temperature on Y-axis.
• Compare and evaluate insulation properties based on performance
• Compare insulation materials based on sustainability ie. aluminium to paper.

Image shows an example of time vs. temp graph.

If an infrared camera is available also measure the exterior of the bottle.

Continue/end the lesson with a discussion of the importance of insulation materials

Follow up activity can be made with IR camera.

Let students create thermographic images of the school to discover where heat is lost and insulation poor.

Discuss where insulation can easily be added and where it is difficult to add insulation.
