Interesting tidbit

[windowmann2000]

The need for replacement windows will remain high for some time but did you ever wonder who sells what and where. An interesting tidbit I came upon was that there are more than 200 Amish window manufracturing facilities making over one million replacement windows a year. Some are mechanically fastened and some welded. The ones I looked at had NFRC labels .30 using Super Spacer low-e and argon. Not bad considering they do very little marketing.
