2.1WATER-RESISTIVE BARRIER

Usually retain this article; a water-resistive barrier over sheathing is inexpensive and is required behind masonry veneers. Delete article if a water-resistive barrier will interfere with exterior insulation and finish systems or similar construction.

Retain one of two "Building Paper" paragraphs or "Building Wrap" Paragraph below.

  1. Building Paper: ASTMD226, Type1 (No.15 asphalt-saturated organic felt), unperforated.

Option in "Building Paper" Paragraph below is based on "Super Jumbo Tex60 Minute" by Fortifiber Building Systems Group.

  1. Building Paper: Water-vapor-permeable, asphalt-saturated kraft building paper that complies with ICC-ESAC38, GradeD[;except with water-resistance rating not less than 1 hour].

Note that ASTME1677 is for air barrier materials for low-rise buildings. This standard allows 15 times as much air infiltration as the limit for air barrier materials in many building codes.

  1. Building Wrap: ASTME1677, TypeI air barrier; with flame-spread and smoke-developed indexes of less than 25 and 450, respectively, when tested according to ASTME84; UV stabilized; and acceptable to authorities having jurisdiction.

  4. DuPont Building Innovations: E. I. du Pont de Nemours and Company.
  5. Kingspan Insulation Limited.
  6. Ludlow Coated Products.
  7. Raven Industries, Inc.
  8. Reemay, Inc.
  9. Insert manufacturer's name>.

Coordinate permeance value retained or inserted in "Water-Vapor Permeance" Subparagraph below with products retained. Consult manufacturers' literature.

  1. Water-Vapor Permeance: Not less than [75 perms (4300 ng/Pa x s x sq.m)] [20 perms (1150 ng/Pa x s x sq.m)] [8 perms (460 ng/Pa x s x sq.m)] <Insert value> per ASTME96/E96M, Desiccant Method (ProcedureA).

"Air Permeance" Subparagraph below is based on ICC-ES and Massachusetts State Building Code criteria for air barrier materials. Note that this requirement is far more stringent than the requirement in ASTME1677 and that most building wrap products cannot comply. Before retaining, consult manufacturers' literature.

  1. Air Permeance: Not more than 0.004 cfm/sq. ft. at 0.3-inch wg (0.02L/s x sq.m at 75Pa) when tested according to ASTME2178.
  2. Allowable UV-Exposure Time: Not less than 3 months.

Retain "Flame Propagation Test" Subparagraph below if required. Tested products are not available from all manufacturers for all types of assemblies.

Adhesive-backed building wrap and accessories are fully adhered to a substrate, versus standard wrap/paper, which is mechanically attached. A fully adhered system provides higher performance in air- and water-tightness versus a mechanically-attached system. The fully adhered installation resists damage from wind and rain during exposure, and the fully adhered system does not allow travel of air or water between the membrane and the substrate. Fully adhered systems should be considered a performance upgrade versus mechanically-attached systems. Due to significant cost and performance differences, adhesive-backed building wrap should not be used interchangeably with standard building wrap or paper.
