Insulation 1 Clever Fiberglass – FT

FIBERGLASS & ASBESTOS: There are different kinds of insulation in a house, One is fiberglass…which is just rocks spun into a fiber!

FIBERGLASS & ASBESTOS:   Thick R-15 insulation is usually put in the ceiling of homes for insulation because heat leaves a house greatly through the roof. 

FIBERGLASS & ASBESTOS:   If you want to be cool in the summer or warm in the winter,  people put a lot of R30 insulation in the walls.  It helps!

FIBERGLASS & ASBESTOS:   Fiberglass makes an amazing insulator.  Little pockets of air get trapped within the fiberglass. This works great as an insulator because gases conduct heat well. 

FIBERGLASS & ASBESTOS:   The fiberglass used in home insulation is manufactured by heating a mixture of sand and recycled glass to 1000º F, twice as hot as your stove gets!

FIBERGLASS & ASBESTOS:  Before fiberglass was used for insulation, a crystal named quartzite was used to insulate homes and buildings.

FIBERGLASS & ASBESTOS:  It is now against the law to use asbestos in buildings construction in the United States–and in many other countries as well. 

FIBERGLASS & ASBESTOS:  The atoms in asbestos are similar to those in glass. But, when it fragments, asbestos–which is a crystal–breaks into fine threads of crystal.  These threads can easily be inhaled. 

FIBERGLASS & ASBESTOS:   Fiberglass is made of fibers of glass.

FIBERGLASS & ASBESTOS:  Even though it is nearly pure glass, when fiberglass is accidentally inhaled, it dissolves in human lungs,  but still cannot be removed by the body.
