`quantitykind:VapourPermeance`

http://qudt.org/vocab/quantitykind/VapourPermeance

Predicate	Object
`rdf:type`	`qudt:QuantityKind`
`dcterms:description`	“A material's "permeance", is dependent on thickness much like the R-value in heat transmission. Dividing the permeability of a material by its thickness gives the material's permeance. Permeance is the number that should be used to compare various products in regard to moisture transmission resistance.”
