Patent abstract
A moisture vapor permeable metalized composite sheet is formed by coating a moisture vapor permeable sheet with at least one metal layer and at least one outer organic coating layer. The moisture vapor permeability of the composite sheet is at least about 80% of the moisture vapor permeability of the starting sheet. The composite sheet provides a barrier to air and liquid water infiltration while having high moisture vapor permeability and good thermal barrier properties. The composite sheet material is suitable for use as a building construction wrap such as roof lining and house wrap.
