The Saturday Video: Keeping Warm with Insulation

By December 10, 2005Cool Stuff Being Made

pwrplant.jpgOver the past weeks and months, we have spent a lot of time here writing about the rising costs of energy (while we’re sitting on enormous reserves). We’ve also said that conservation and new supplies are not mutually exclusive. In fact, we need to do both. One thing that helps conserve energy is insulation. So in keeping with our energy theme, 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. Thanks to the good folks at CertainTeed for this excellent video.

    The video ends with something like “Without insulation, what a different world we’d live in.”

    Yes, a world like Japan. Where every room is freezing in winter and must be individually heated, either by wall-mounted heaters, kerosene heaters, or radiating heaters. I’m not sure about modern homes, but every home I’ve been in, and talked about with my adult ESL students is like this.

    I’m not exactly sure why they don’t use insulation here. I’ve heard a few reasons: without proper ventilation, the tatami mats (made of rice straw) would rot in the summer; because of lack of space, walls are made too thin to accomodate insulation; because of sliding doors, some walls must allow for a door to slide into it.

    Whatever the reason, it’s very cold inside homes here in the winter!
