WebAug 1, 2024 · The freezing point (32°F) is a critical temperature threshold for many aspects of life. The number of days with temperatures below freezing, and when these days occur, can affect natural ecosystems as well as many sectors of the economy. For example, many crops only grow during periods when they are not limited by frost damage. 1 Webdesigned for a climate with an Air-Freezing Index (AFI) of 2,000°F with a 100-Year Return (winter) Period. An FPSF incorporates strategically placed insulation to raise soil temperature and the frost depth around a building, thereby allowing foundation depths as shallow as 16 inches for almost all areas of the continental U.S.
