Hi, You can use a infrared imager and view through it to see where your walls are warmer and also you can use a lazer digital temperature meter to do much the same.
This will show you the uneven heat loss through uninsulated walls and insulated walls so you'll pretty much know where you stand. Hope this helps: Jimiwane
Most houses have insulation in the walls. Copper wire is coated in plastic for insulation.
By using acoustic insulation in the walls.
Insulation is relatively cheap, certainly when compared to the possible gain in terms of heating costs. Rolled insulation or "batts" of insulation can be put up very easily if your walls are open. If your walls are closed foam is still a possibility.
In the ceiling and the walls
The walls, the roof, and insulation.

above ground pool walls have insulation in them
Foam or fibre insulation.

the insulation can collect moisturethe insulation can fall through the walls to lower floors (this is true of some blowin/pourin insulation types)etc.
