we have numerous recessed light fixtures in our ceiling. Is fiberglass insulation flammable?
Is Loft Insulation Flammable
The fiberglass or the paper may contact the light housing without any risk of fire, the housing is designed to shield the insulation from the heat. You could even put blown-in insulation next to it.

Fiberglass insulation will not burn. If it is the blown in loose fill kind, then there should not be any paper or anything attached to it to make it flammable. You should have what is called a light dam around it to keep insulation from covering the top of the light. It is actually quite common for insulation to be in contact with the sides of the light but it should not cover the top. Of course, if you have what is called and I.C. rated recessed light, then it has it's own protection built in. These are usually pretty rare and not used by home builders generally. We always play it safe and put light dams around every recessed light we find. This light dam is a class a fire rated piece of radiant barrier taped together to form a tube that is taller the the insulation around it so that insulation can not easily be pushed over the top or blown into the top of the tube if installing new insulation.
Do you have the paper on the insulation? You should not have the insulation right up to the fixture.The fiberglass is not flamable, but it can melt if it gets too hot
