Product information

Product name

HP+™ R Series - Air Barrier System

Product description

This Report addresses the performance of the product as an air barrier system (ABS) as specified by BASF Canada Inc. (BASF). The "HP+™ R Series - Air Barrier System" consists of the following components and accessories:

  • principal material in the plane of airtightness: "WALLTITE® CM01"Footnote  spray polyurethane foam insulation by BASF (CCMC 14100-L);
  • accessories for continuity:
    • "3M™ Air and Vapour Barrier 3015," a self-adhering, proprietary elastomeric flashing with acrylic adhesive that is manufactured by 3M Canada for use as a transition membraneFootnote (1) over construction, control and expansion joints, at junctions between different assemblies, and at penetrations; and
    • "MasterSeal® NP 1™" by BASF or "Dymonic®" 100 by Tremco, for use at membrane-to-foundation junctions and on the interior side around window and door openings; and
  • component for wind load resistance: structural substrate, such as "Neopor® Graphite Polystyrene" (GPS)Footnote (2) by BASF, oriented strandboard (OSB), plywood, or exterior gypsum sheathing within a wall designed to withstand the anticipated positive and negative wind loads.Footnote (3)

If installed as part of the designated ABS, WALLTITE® v.3 spray polyurethane foam serves a dual function in the wall assembly: as the principal plane of airtightness of the designated ABS and as exterior insulation. The use of the product as insulation is covered under CCMC 13588-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 to install the product. The resulting product is a spray polyurethane 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 proprietary ABS, it must be installed at a minimum thickness and density, which are specified in the Conditions and limitations section of this Report. As per CCMC 14100-L, the finished product is purple.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

Air barrier system

  • The durability assessment of "WALLTITE® CM01" (the principal material of the ABS) has demonstrated sufficiently low air permeance at a thickness of 25.4 mm and a minimum field (in-place) density of 39 kg/m³. This meets the intent of Subsection 9.25.3., Air Barrier Systems, of Division B of the NBC 2010 and 2015 for buildings with an indoor relative humidity (RH) of 35% or less. For buildings with a higher RH (e.g., swimming pools and museums), additional assessment is required in accordance with Part 5, Environmental Separation, of Division B of the NBC 2010 and 2015.
  • The evaluation of "HP+™R Series - Air Barrier System" is limited to wood-frame construction that meets the requirements of Part 9, Housing and Small Buildings, of Division B of the NBC 2010 and 2015. The air leakage rate of the tested wall assemblies, following structural aging, meets the rating A1 (less than 0.05 L/(s·m²) at a pressure difference of 75 Pa) when tested in accordance with CAN/ULC-S742-11, “Air Barrier Assemblies – Specification.” The wall assembliesFootnote (4) have demonstrated sufficient strength to resist wind loads so they can be used in buildings that fall under the provisions of Part 9 of the NBC 2010 and 2015, in geographical locations where the wind pressure is Q1/50 ≤ 1 000 Pa for a maximum building height of 12 m. The Q1/50 corresponds to the 1-in-50-year wind pressure return period published in Appendix C of Division B of the NBC 2010 and 2015. For applicability of the ABS rating and durability of the components, in wood-frame construction beyond the provisions in Part 9 of the NBC 2010 and 2015, the stamp of an engineer is required for acceptance by the authorities having jurisdiction (AHJs).
  • To provide the air leakage control and strength in the field, the product must be installed in conformance with the limits above. It must be installed in the field by Caliber Quality Solutions Inc.-certified installers according to “HP+™ R Series walls - Technical Installation - 3D details - version 2019”, “HP+™ Wall System R Series Field Assembly Guide" dated May 30, 2019, and “HP+™ R Series Installation Details" dated April 8, 2019. Caliber Quality Solutions Inc., a third-party inspection agency, must conduct the necessary follow-up inspections to ensure that Caliber Quality Solutions Inc.-certified installers are performing the necessary field quality control; for example, transition membrane application, membrane adhesion / pull testing before spraying, sealant application before spraying, and 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 Quality Solutions Inc. daily worksheet for the "HP+™ R Series - 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 "WALLTITE® CM01" installers must present their Caliber Quality Solutions Inc. identification card upon request by the building official.

Additional data

Data in this section does not form part of the CCMC’s opinion in Section 1.

The following test data are provided for information purposes only, as the CCMC’s opinion of the product’s compliance with NBC 2010 and 2015 stated in this Report is limited to a maximum building height of 12 m for buildings that fall under the provisions of Part 9 of the NBC 2010 and 2015. For the applicability of the ABS rating and durability of the components, in wood-frame construction beyond the provisions in Part 9, the stamp of an engineer is required for acceptance by the authorities having jurisdiction (AHJs).

The third-party testing laboratory that conducted the air leakage tests in compliance with CAN/ULC-S742 also reported the following sustained hourly wind pressure loads and its corresponding building heights (see Table 1 in Annex G of CAN/ULC-S742) beyond 12 m:

  1. Q1/50 sustained hourly wind pressure load 0.450 kPa (450 Pa) and building height of 60 m;
  2. Q1/50 sustained hourly wind pressure load 0.550 kPa (550 Pa) and building height of 20 m;
  3. Q1/50 sustained hourly wind pressure load 0.650 kPa (650 Pa) and building height of 20 m;
  4. Q1/50 sustained hourly wind pressure load 0.750 kPa (750 Pa) and building height of 20 m; and
  5. Q1/50 sustained hourly wind pressure load 0.850 kPa (850 Pa) and building height of 20 m.

The tested wall specimens did not lose their integrity during the wind pressure loading.

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.

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:
