Are fiberglass doors good for insulation?

Fiberglass doors have an exceptionally insulating polyurethane foam core that provides a high R-value. The R-value is a standard measure of insulation effectiveness; higher numbers mean better insulation. Most fiberglass doors without windows fall in the R-5 to R-6 range — a significantly higher R-value than wood.

Are wood front doors insulated?
