Pat writes in with these week’s video from the Manufacturer’s blog! “…here is this week’s video of fiberglass insulation being made. The opening screen says, “Sand to Glass to Fiber Glass.” You’ll see here the process from sand to glass, and recycled glass, through 2500-degree ovens and eventually into fiberglass insulation. This is a substance that will be keeping us warner this winter, thought you might want to see how it’s made. The plant you see here makes enough insulation each day to insulate 250 homes.” Link.
