I am having trouble deciphering the difference between convection and conductionIn thermos type of thing, what would insulation foam be stopping, convection or conduction?So basicallyHow does spray insulation foam insulate things, and use terms convection and conduction please?(explain please)And how would adding layers to a thermos make it retain heat better?Thanks a lot for any answers in advance.
This is an easy oneJust go or call your local boat dealershipThey usually carry products to improve your boat with many types of marine paint and might give you informationMany or all auto paints will also workThe preparation for painting is the same as painting a car.
In thermos type of thing, what would insulation foam be stopping, convection or conduction? Convection How does spray insulation foam insulate things, and use terms convection and conduction please? It does both Well it has pockets of air (little bubbles) which slow heat transfer via convectionConvection requires moving currents of airHot air raises and takes heat with itThat is replaced by cold air, which heats and raises, etcThis is called 'convection currents.' Metals conduct heat better than nonmetalsThis foam is made of monmetallic compounds which lower heat loss by conduction And how would adding layers to a thermos make it retain heat better? The extra layers of any insulating material provide more resistance to the flow of heatExample a log (solid wood) house has drastic temperature changes from the inside part of the wall and the outside part Heat is passed by conduction thru solid objects, and thicker, more layers slow this transfer.
