Basic physical science laws dictate that more energy is required to convert any given volume of water from vapor to liquid (970 btu’/ lb) known as latent heat, than is required to change temperature measurable on a thermometer by one degree (1 btu’/ lb/ degree) known as sensible heat. Excess moisture means higher energy bills. Properly designed vapor barriers reduce this energy drain.
