Having better insulated homes would benefit you guys too. Your energy needs to cool the house would be much lower unless you're resistant to melting.
Ian what part of the great white north are you living in? I lived all my life near Vancouver and moved here to Saskatoon last September. Fortunately we had a mild winter and got broken in gently.
I also apologize for the thread derail.

in Australia the extra dollars are nearly always better invested in wider eaves rather than thicker wall insulation. If you can keep the sun off the walls and windows, especially the west facing ones, the solar heat load is greatly reduced. even external blinds or security shutters can make a significant difference to the solar heat load.

Hi Cava
While you are in the information gathering/dreaming/doodling phase for you new house you might like to do some googling on the European passivhaus concept. I have seen estimates that they increase building costs in Australia by 5-10%, but if that reduces heating and cooling costs by 90% then the payback period should be quite short. Shorter if energy costs continue to rise.
Just a thought.
Cheers
Graeme

I know
what I'm alluding to is that US / European insulation standards, building codes and products are designed to deal with a temperature gradient between the inside and outside of a dwelling that is in the order of 40 to 60 degrees C (-25 outside, +25 inside = 50 degrees difference)
Even in Melbourne the temperature gradient will rarely be greater than about 20 to 25 degrees.
If I were an insulation salesperson or builder I'd happily sell you more insulation (think the "rinse and repeat" mantra to sell additional hair shampoo) but will the customer ever recover the increased costs in energy savings, especially if they team teh additional insulation with roof top solar.regards from Alberta, Canada
