February 1, 2014

Product Characteristics of Weather Barriers,
Vapor Retarders, and Finishes

Fabrics are often
coated and used as insulation jacketing materials, particularly for
removable/reusable insulation covers. The fabrics are woven from a wide variety
of textile fibers including, but not limited to:

  • Canvas

  • Fiberglass (Type E)

  • Amorphous silica fibers

  • Ceramic fibers

  • Aramid fibers

  • Stainless steel

  • Inconel

Coatings and laminate
membranes are usually applied to these fabrics to provide increased protection
and abrasion resistance. Common coatings include, but are not limited to:

  • Acrylic

  • Silicone

  • Polytetrafluoroethylene

  • Polychloroprene

  • Vermiculite

The selection of the
fabric/coating combination for a particular application depends on the
temperature, abuse, chemical compatibility, and combustibility requirements.
Consult manufacturers of fabrics or removable/reusable covers for guidance.
