The insulating properties of fabricFeatured science projectScience project video


This experiment was conducted to compare the ability of different types of fabrics to keep us warm on cold days. The tests were done using air, Thinsulate and cotton fleece.


Thinsulate fabric retains heat and keeps water in a flask warm for the longest period of time,

Clothes to keep warm

Clothing protects us from the sun on hot days and helps to keep us warm on cold nights. It also protects us from injuries, insect bites and extreme weather conditions like strong winds, rain or snow.

The type of clothing used will vary between different countries and cultures. Human beings have survived by adapting and modifying the clothes we wear to suit our environment. Some cultures living in warm regions like the African deserts , require little clothing. Others living in colder climates wear thicker and denser clothing.

Choosing the correct type of clothing to wear is especially important in countries with 4 seasons. Materials used in clothing like cotton or wool are normally poor conductors of heat. There is air, which itself is a thermal insulator, trapped in between the gaps in the fiber to help keep us warm. Both natural fibers and synthetic fibers are used in making clothing for different climates.
