Abstract: The present invention provides a fibrous veil having a plurality of densified portions formed thereon for improved airflow resistance. The airflow resistance may be tuned to meet the needs of a particular application by selecting the size, density and location of the densified portions. The veil may be used independently or in combination with other sound control materials. The present invention also provides a fibrous blanket having a plurality of densified portions formed on one or both major surfaces thereof for improved airflow resistance. The airflow resistance may be tuned to meet the needs of a particular application by selecting the size and density of the densified portions. A method of manufacturing the materials of the present invention by applying heat and/or pressure to portions of the material is also presented.

Abstract: Disclosed are an insulation product and an insulation system incorporating such a product for insulating exterior walls, particularly masonry walls, that incorporates a wicking media to transport condensate away from the interface between the insulating product and the exterior wall. The condensate will be removed to a more interior location where it can evaporate and/or be transferred to and held in a sorbent material until conditions allow permit evaporation. The insulation system includes an integrated support element that can be used to increase the rate of evaporation via various methods and/or improve the aesthetic appearance of the insulating product. The evaporation rate may be improved through the use of increased wicking material area, secondary evaporative surfaces, heating and/or forced or natural convection.
