Can you add UV protection to glass?
While standard glass can block some of the harmful UV rays from coming through, it is not enough on its own. The most common method for doing this is by applying a permanent UV coating to the glass.

Does all acrylic block UV?
Most acrylic plastics will allow light of wavelength greater than 375 nm to pass through the material, but they will not allow UV-C wavelengths (100–290 nm) to pass through. Even very thin acrylic sheets of less than 5 millimeters (mm) do not let UV-C light penetrate.
Does clear plastic block UV rays?
Transparent plastics allow more sunlight and more UV rays to enter the greenhouse than opaque plastics do, and the modern polyethylene bubble-wrap sheeting is more effective for blocking out UV rays than standard polycarbonate coverings.
