Re: Quartz heater: Asorption length of short wavelength IR in air? ... It is an old building and the glass looks anything but special, so I assume it is not polished plate, not glare reducing, and it is certainly not colored. ... Right around 2.5 micron, transmission transitions from 45% to below 25%. ... Assuming that absorbed IR robs energy from what would otherwise be transmitted an reflected, let's knock 5-10% off the reflected energy. ... For double-layer windows, we can assume the absorbed energy is converted to heat at the window and lost to the outside immediately through conduction, since there is such a temperature gradient to the outside. ...
