Insulation come hither

As some people know, most homes have little (if any) insulation to keep them warm (or better, "not freezing") in the winter. Thus, homes are freezing in the winter. So, why don't all Japanese people die each winter? Because, they've come up with ingenious heating devices to keep them warm. Some of these devices are portable (as there is no central heating) and some are wall-mounted.

I spoke of this in a previous post (Winter's here! Winter's here!) but failed to mention the kotatsu. This is a low, square or rectangular table which has a radiating downward-pointing fan on its underside, and which people stretch their legs under, and read or play cars or drink tea. A kotatsu blanket is draped over the table and hangs to the floor so very little heat can escape. We have one of these and I'm anxious to set it up.

These words were inspired by a video on how insulation is made, which you can watch here.
