You don't need to work out how thick insulation needs to be; the builder will have a handle on the relevant building regulations.

Car makers currently use thick insulation and customised tyres for this but it cuts fuel efficency.

There's a state-of-the-art heat exchanger which circulates fresh, warm air throughout the house and this, combined with triple-glazing and thick insulation, heats the first and second floors.

There are six cables running along each wall, each about in diameter with thick insulation.

The thick insulation prevents arcing from the cable to an earthed engine component.
