My wife and I are having a house built in New Jersey, and I have some questions about the most energy efficient types of blinds,drapes etc. The house has forced air central heating and wood framed therma-pane windows. Given this set up, does anyone have any recommendations as to the type of window coverings we should use. To maximise heat retention in Winter and minimize heat absorption in the summer. Looks are important ie we're not wanting to put up silver and black coverings. I will summarize if there is much response. Thanks, Ken Cochran 201-834-2283 mtuxo!kwmc

Thermal indoor shutter: R-6.0 (FTR shutters) to R-2.5 (Wallrich) Roller shade: R-2.5 (Appropriate Technology) to R-1.5 (Solar Energy Components) Storm Windows: R-1.1 (sheet construction) to R-0.9 (film construction) Draperies and liners: R-0.9 Standard window shades: R-0.6 Note the higher the R-value the better.

Note too that even if you didn't care for looks, black coverings would not be a good idea since they would absorb light energy and become hot during the day in summer and would radiate away energy as infrared rays at night in winter. Better silver or white. -- ------------------------------- Disclaimer: The views contained herein are | dan levy | yvel nad | my own and are not at all those of my em- | an engihacker @ | ployer or the administrator of any computer | at&t computer systems division | upon which I may hack. | skokie, illinois | -------------------------------- Path: ..!ihnp4!ttrdc!levy
