Product information

Product name

WALLTITE® CM01 - Air Barrier System

Product description

This evaluation addresses the performance of the product as an air barrier system as specified by BASF Canada. The WALLTITE® CM01 air barrier system consists of the following components and accessories:

  • principal material in the plane of airtightness: WALLTITE® CM01 spray polyurethane foam;
  • accessories for continuity:
    • Blue Skin®, a modified bituminous membrane (i.e. peel-and-stick or thermally fused) manufactured by Henry® Company for use as a transition membrane* over construction, control and expansion joints, at junctions between different assemblies and at penetrations; and
    • MasterSeal® NP1™ by BASF Canada and Polybitume 570-05 by Henry® Company sealants, for use at membrane-to-foundation junctions and for use on the interior side around window and door openings; and
  • component for wind load resistance: structural substrate, such as concrete block or exterior gypsum sheathing within a wall designed to withstand the anticipated loads.

If installed as part of the designated air barrier system, WALLTITE® CM01 spray urethane foam serves a dual function in the wall assembly: as the principal plane of airtightness of the designated air barrier system and as exterior insulation. The use of the product as insulation is covered under CCMC 14100-L.

The foam insulation consists of two components:

  • Elastospray® 8000A isocyanate, and
  • a polyurethane resin identified as WALLTITE® CM01.

The two components are mixed on site by an installer approved by BASF Canada to install the product. The resulting product is a Type 2 spray urethane with an assigned long-term thermal resistance value of 1.82 m2×°C/W per 50 mm. If the foam insulation serves as the principal component in the BASF Canada proprietary air barrier system, it must be installed at a minimum thickness and density, which are specified in the Conditions and Limitations section of this evaluation. As per CCMC 14100-L, the finished product is purple.

*The original full-scale testing was carried out with one proprietary transition membrane. Other proprietary membranes are qualified for use by BASF Canada through a small-scale tension test (i.e. WALLTITE® CM01 sprayed specimens over various substrates) to ensure the equivalent adhesion is maintained.

  • To provide the air leakage control and strength in the field, the product must be installed conforming to the limits above and installed in the field by Caliber-certified installers/contractors according to the Master Specification WALLTITE® CM01 - Spray Polyurethane Foam (HFO) Insulation/Air Barrier Material dated April 13, 2021, which contains construction details that must be followed. Caliber must conduct the necessary follow-up inspections to ensure that Caliber-certified contractors are performing the necessary field quality control (e.g. transition membrane application, membrane adhesion/pull testing before spraying, sealant application before spraying, spray foam as per CAN/ULC S705.2-05, “Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density – Application”). All results must be recorded on the Caliber daily worksheet for the WALLTITE® CM01 air barrier system.
  • A copy of the installation instructions must be available on the job site at all times during the installation for review by building officials. All installers must present their Caliber identification card upon request by the building official.
  • The product must be identified with the manufacturer’s name or logo and the phrase “CCMC 13659-R.”

The product must be installed on-site by BASF Canada-trained installers following the BASF Canada specified product installation manual entitled WALLTITE® CM01 Application Guidelines, and dated November 30, 2020, which contains detailed construction drawings which must be followed (see Specimens tested for qualifying system details of this evaluation for examples). In addition, Caliber carries out follow-up inspections of the installations on a periodic basis.

 

Air barrier system – field quality assurance

When the WALLTITE® CM01 spray urethane is applied as the designated air barrier system, BASF Canada requires that the installer be BASF Canada-trained and that Caliber conduct audits to ensure:

  1. the approved accessories are being used;
  2. proper installation of the transition membrane by conducting periodic tension testing as part of the BASF Canada-specified quality control;
  3. proper continuity details and substrate conformance as part of the quality control procedure for the product;
  4. proper application of the WALLTITE® CM01 spray foam; and
  5. daily work records are maintained for the air barrier system installation.

Insulation – field quality assurance

When the proposed spray polyurethane is applied as spray-foam insulation, the material must be manufactured on site by qualified installers licensed by BASF Canada with field inspections carried out by Caliber. Caliber certifies BASF Canada’s training program and provides follow-up inspections to ensure installations are in accordance with CAN/ULC-S705.2-05, “Standard for Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density, Installer’s Responsibilities – Specification.”

The product must be installed in accordance with the manufacturer’s installation manual. A copy of this manual must be available on the job site at all times during the installation. All installers must present their BASF Canada licensing card and specific site worksheet upon request by the building official.

Note: the BASF Canada field quality assurance program calls for periodic audits of the installers, usually random inspections with some mandatory inspections of larger projects. Building officials may contact BASF Canada (866-474-3538) and request an inspection for a specific job site if they deem it necessary. In cases where the installation is deemed non-conforming by Caliber/BASF Canada and is not remedied by the installer, Caliber/BASF Canada will inform the owner/architect/building official of the non-conforming installation.

See CCMC 14100-L for additional limitations on the installation of the WALLTITE® CM01 spray-foam product.

Elastospray® 8000A isocyanate and the polyurethane resin WALLTITE® CM01 must have their containers (i.e. drums) identified by the phrase “CCMC 13659-R” and “CCMC 14100-L,” respectively.

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

National Building Code of Canada, Sentence A-1.2.1.1.(1)(a)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

  • complying with the applicable acceptable solutions in Division B, or
  • using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.

Code compliance as an alternative solution

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.
