From Environmental Building Physics: Why a Cold Window Chills a Warm Room
Doubling the thickness of insulation in a wall does what to the heat flow through that layer?
- Roughly halves it
- Cuts it to a quarter
- Stops it almost entirely
Show the answer
Answer: Roughly halves it
Conductive heat flow is inversely proportional to thickness, so each doubling halves it; the savings shrink in absolute terms with every extra layer.
