Heating fuel is very expensive in bush Alaska, as is window glass. Small windows help with both.

Just went through some of this myself. The R value of very good triple pane glass is R5 or so.

About the same R value as a wall made of 2x4s with no additional. Or about the same a 1” of extruded foam.

So… pretty poor.
