1. An opening assembly for a building opening, comprising:
a frame having one or more insulating members, each of the one or more insulating members includes a high-density insulating core, each high-density insulating core having longitudinal sides and being at least partially encased by one or more wood components on at least two opposing longitudinal sides of the high-density insulating core;
wherein the high-density insulating core of each of the one or more insulating members is made of microcellular polyurethane; and
wherein the high-density insulating core has a uniform density of microcellular polyurethane foam that does not deviate by greater than ten percent throughout the high-density insulating core.
