1. Opinion

It is the opinion of the Canadian Construction Materials Centre (CCMC) that “1585CW-P2 Sheathing Tape, 3M 8088, 1585CW-P2 Typar HouseWrap”, when used as a sheathing tape in accordance with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:

  • Clause 1.2.1.1.(1)(b), Division A, as an alternative solution that achieves at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the following applicable acceptable solutions:
    • Sentence 9.27.3.3.(2) Required Sheathing Membrane and Installation
    • Sentence 9.27.3.3.(3) Required Sheathing Membrane and Installation

This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.

2. Description

The product has a permanent acrylic adhesive coating on an oriented polypropylene backing. The product is available in red or white and in rolls that are 66 m long and 60 mm, 64 mm, 76 mm or 102 mm wide.

3. Conditions and Limitations

CCMC's compliance opinion in Section 1 is bound by the “1585CW-P2 Sheathing Tape, 3M 8088, 1585CW-P2 Typar HouseWrap” being used in accordance with the conditions and limitations set out below.

  • The products can be used to tape butt joints in the Tyvek® HomeWrap™ (see CCMC 12808-R) and the Tyvek HomeWrap®– Air Barrier Material™ (see CCMC 12857-R). They are permitted to be used in new and existing residential construction, subject to the following conditions:
    • the tape can be applied at temperatures as low as –10°C, however, adhesion increases with warmer temperatures; and
    • the products' shelf life is 1 year from the date of receipt by the customer when stored under optimum conditions of 21°C and 50% relative humidity.
  • The products must be installed in accordance with the manufacturer's current instructions, which include the following recommendations:
    • for optimum adhesion, surfaces should be relatively clean and dry
    • do not apply to wet facing or wet wood
    • use of the 3M PA-1 Tape Wiper is recommended to ensure proper rub down of the tape
    • apply tape to all joints and tears in the substrate
    • all joints must be butt joints not exceeding 10 mm in width or lap joints with the tape centered on the joint
  • Each roll must be identified with the manufacturer's name and the CCMC Evaluation Report number at intervals not exceeding 300 mm.
