Happy for you, most houses I visited in Canada are so poorly insulated (noise and temperatures) that it's laughable and triple glased windows would just move the problem from windows to walls.

Asked a home building company if they build with concrete (not that you couldn't insulate a wood construction though) and they scoffed saying it would take 15 years to recoup the costs through energy savings... Which doesn't sound that long to me, it's a house not a car
