Looks to me like a fiberglass insulation. Wouldn't be that hard to make but I won't ever have a wood exterior door on a southern exposure again. Had one and had to revarnish it every year. The direct sun was very hard on it. As most SI homes have thicker than standard walls a 3 or 4" thick foam core door would be doable. Fiberglass frame and cover would be ideal.
