I read somewhere that rays from a UVB lamp are affected when directed through a screen. Is this so? What about the type of screen material used? Perhaps the type used on screened doors (also the type used on terrariums designed for reptiles) are not metal screens, but a type of tough plastic or resin, which doesn't affect the UVB rays?
