WebSep 17, 2013 · Most spray foam manufacturers spec a surface temperature range between 60°F and 80°F. An uninsulated wood sill on a very cold January day could easily get below 60°F. Hell, it would probably get below 45°F. This problem can easily be sussed out with a simple laser thermometer. WebApr 25, 2012 · The effect of sample size on radiant smouldering ignition had been theoretically proposed before but this is the first time that it is demonstrated experimentally. The onset of smouldering ignition was observed in the ranges 13–14 kW m 2, 8–9 kW m 2, 7–8 kW m 2 for 50 mm, 100 mm and 140 mm sample sizes respectively.
