Thermal Insulation
⭐ MasteredInsulation slows down the movement of heat. Materials like wool, foam and air pockets trap heat, which is why winter coats and double-glazed windows keep warmth in.
💡 Fun fact
Air is a very good insulator, which is why many jackets trap air inside their padding.
All about Thermal Insulation
Insulation slows down the movement of heat. Materials such as wool, foam and trapped air are good insulators because they stop heat moving through them quickly. This is why winter coats keep you warm and double-glazed windows keep warmth inside a house.
Air is a very good insulator, which is why many jackets trap air inside their padding. Builders also add insulation to walls and roofs to save energy and keep homes comfortable.
