Glass wool, also known as fiber glass it is a type of insulation material made from recycled glass that is melted and spun into fibers
Glass wool, also known as fiber glass is made from a mixture of natural and recycled glass (recycled bottles, car windscreens and window panes) which is melted at 1,450 °C, and is then spun quickly to create fibers.
These fibers are then bound together to be used as insulation. The glass fibers create pockets of air which act as barriers to prevent heat loss, because air is a poor conductor of heat. Glass wool can be found in batts and rolls and also within insulation boards.
