Lead foil
From Halopedia, the Halo wiki
Lead foil is a material composed of lead used by the UNSC for ships that traverse slipstream space. Lead foil is essential to slipspace travel, and to deep-space travel in general, as it absorbs radiation and prevents it from harming the occupants of the ship. Lead foil is relatively fragile and prone to melting at extreme temperatures.
Lead foil can be found on most UNSC deep-space ships, in addition to the Long range stealth orbital drop pods.[1]
Covenant ships apparently do not use lead foil, particularly Dextro Xur-pattern Spirit dropships, which are not capable of navigating slipspace. However, lead foil can be installed in them to achieve the desired effect. Blue Team did this to their dropship aboard the Ascendant Justice shortly before Operation: FIRST STRIKE.[2]
