An outer air seal includes a seal wall, a heat shield, a side wall and a blade seal disposed radially inward of the seal wall. The seal wall has axially opposed first and second ends. The heat shield is radially outward of the seal wall and has first and second ends axially opposed ends. The second end of the heat shield is joined to the second end of the seal wall. The side wall is between the seal wall and the heat shield and spaces the first ends of the heat shield and the seal wall apart to form an inner cavity therebetween. Inner and outer diameter ends of the side wall are joined to the first ends of the seal wall and of the heat shield, respectively. The heat shield is configured to thermally isolate an outer case from the inner cavity and the seal wall.
