Permeability (0°C)
perm (0°C)
Definition
The permeability at 0°C is a traditional unit of permeability used in building materials and textiles, representing the vapor transmission rate through a material at 0 degrees Celsius. It is commonly used in the construction industry for measuring moisture vapor transmission.
History/Origin
The permeability at 0°C was developed in the building materials industry as a practical unit for measuring moisture vapor transmission through construction materials. It became standardized for comparing the breathability of different building materials and textiles.
Current Use
Permeability at 0°C is extensively used in the construction industry, textile manufacturing, and building materials testing where moisture control and vapor transmission are critical for material performance and building envelope design.

Permeability Inches (0°C)
perm·in (0°C)
Definition
The permeability inches at 0°C is a unit of permeability used in the US building industry, representing the vapor transmission rate through a material at 0 degrees Celsius per inch of thickness. It provides a thickness-normalized measure of material permeability.
History/Origin
The permeability inches at 0°C was developed in the US building industry as a practical unit that accounts for material thickness in permeability measurements. It allows for direct comparison of materials with different thicknesses in construction applications.
Current Use
Permeability inches at 0°C is used in US building codes, construction specifications, and material testing where thickness-normalized permeability values are needed for proper material selection and building envelope design.
