Heat Flow Rate vs Thermal Conductivity (k)

Formel

Fourier's law describes the rate of heat conduction through a material.

Q/t = k * A * DeltaT / d

where k is thermal conductivity, A is area, DeltaT is temperature difference, and d is thickness. Lower k means better insulation.

Heat loss through a 10 m² wall, 10 cm fiberglass insulation (k=0.04), 20°C temperature difference.

What materials have the highest thermal conductivity?

Silver (429), copper (401), and aluminum (237) in W/(m·K). Metals are generally excellent conductors.

What makes a good insulator?

Materials with very low thermal conductivity: fiberglass (~0.04), styrofoam (~0.03), aerogel (~0.015), and still air (~0.025 W/(m·K)).

How does wall thickness affect heat loss?

Heat loss is inversely proportional to thickness. Doubling the insulation thickness halves the heat loss rate.
