Tile gap fillers fit into the spaces between tiles to close any narrow gaps. About the size of a bookmark but a bit thicker, the gap filler is a barrier that keeps heat from penetrating around the tiles. Gap fillers have black or white braided borders, according to their use between black or white tiles. They are made of a tough ceramic silica fiber strengthened with aluminum. NASA gave this gap filler to the Museum after the Space Shuttle Columbia's first mission in 1981.
