  If an object is not exposed to environment and is in contact with other objects with no gaps, will this object still radiate heat ? As conduction will take place but since its not exposed to any vacuum/air/environment from anyside.

  Hi,
  If you do not define any radiation boundary condition then no radiation takes place:
  17.6.2.19. Radiation

  Potentially - is it transparent to an important wavelength.
