Are they flammable at all?

They will burn in high enough heat, although they should not sustain a
flame on their own.

One of the risks in rooms that are fully insulated, it that they can
reach a combustible temperature much more quickly than an uninsulated
room. So a small fire can spread to spontaneous ignition of other things
in the room quite quickly.
