INSULATING SNEETROC.K BRIEF HISTORY A few years ago, foil insulation was unknown-in this country. Its introduction was a slow, laborious process. The principle of reflective insulation was re ceived by the public with much doubt, skepticism and argument. Many stocks of foil board and foil covered paper lay in dealer's warehouses for lack of demand. For a salesman to open the subject of foil insulation v;as equivalent to a challenge to debate. The prospect could tell dozens of reasons why it wouldn't work. It would "oxidize, collect dust, corrode, peel off, refuse to insulate except under ideal summer conditions", and many other gloomy drawbacks. The salesmen were too busy selling bread-and-butter products to spend hours wrangling over theories. IT13 DIFFERENT NOW. Let us skip over the intervening years. It's 1941 now. Millions of feet of Sheetroc:c and Rockiath foil are "in there pitching". Architects no longer question it. Kirchoff's law of emissivity must have been repealed, because nobody seems to enjoy a good argument about it any more. Now-a-days we say "Of course it works - Ten years of experience in actual buildings backs up the findings of 71 years in scientific laboratories." Even the die-hards are asking where they can get it, instead of asking how it works. WANTED - Orders for Insulating Sheetrock.
