On the other hand, most sunlamps aren't made of ordinary glass--they're made of quartz or special UV-transparent glass.

(Light with wavelength greater than 4,000 A lies in the visible spectrum.) The most potent rays for burning and tanning lie in the 2,900-3,050-A range, with radiation of 2,967 A supposedly being most effective of all.

 Ordinary window glass, however, is pretty much opaque to wavelengths below 3,000 A. From this we deduce that the intervention of a window will significantly reduce but not halt the burning/tanning process.
