If you're looking at the earth from outerspace, does it rotate clockwise or counterclockwise? (not around the sun - but just around.) I've tried doing the research, and haven't gotten anywhere. So please let me know where you found your info, if you can. Thanks.

I am insulating a cellar and have been given various U values I have to achieve, all companies give their own calculations, but will not show how a result is acheived, which does not give me a choice of materials or combination of materials! only what they will supply. If someone could be unbiased and give me an idea how it's done it would be appreciated
