Thermal resistances of layers in series

Calculates simplified overall heat transfer coefficient as the inverse of total area-specific thermal resistance.

Calculates indicative heat loss through a flat barrier from area, temperature difference, and thermal resistance.

Calculates conduction thermal resistance of a flat layer.

Calculates convection thermal resistance from h and area.

Calculates required insulation thickness from thermal resistance, conductivity, and area.

Calculates heat-loss energy through a partition from U-value, area, temperature difference, and time.
