Required insulation thickness

Calculates required thermal resistance from allowable heat loss, area, and temperature difference.

Calculates conduction thermal resistance of a flat layer.

Sums thermal resistances of multiple layers connected in series.

Calculates required flat insulation thickness from conductivity, area, temperature difference, and allowed heat loss.

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

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