Recommended: Dense-pack wall insulation + attic air sealing to R-60+
Alaska's extreme heating season makes insulation one of the highest-ROI home improvements. Super-insulation to R-60+ attic and R-21+ walls is standard for new construction. Weatherization funding is more available here than almost any state.
