I have had dragons for a couple years now and never thought to ask, do uvb rays travel threw regular household window screens? I often put my dragons on the window sills during the spring, summer and fall and thought I would ask if uvb rays are reaching them? I have a 5.0 reptisun bulb in every enclosure and I take them in direct sun outside when I can, but I was just curious if the scenic days are doing them good as well as entertaining them :) Thanks, LM
ps. It probably sounds stupid, but with all the fancy screening they have you never know if some block uvb etc.
