Product information

Product names

  • BASF HP+™ XR - Air Barrier System
  • BASF HP+™ XR-S Series - Air Barrier System

Product description

This evaluation addresses the performance of HP+ XR and XR-S Series – Air Barrier System as a proprietary ABS designated by BASF Canada Inc.

General description of the assemblies
  • HP+ XR Series: WALLTITE® CM01 polyurethane foam sprayed between wood studs (installed at 406 mm (16 in.) o.c. and 609 mm (24 in.) o.c.) and over metal or wood girts supporting Neopor® Graphite Polystyrene (GPS) board. Figure 1 and Figure 2 in Air barrier system details show the assembly with horizontal metal girts and Figure 3 and Figure 4 show the assembly with horizontal wood girts.
  • HP+ XR-S Series: the same wall assembly as HP+ XR Series with the exception of a 12.5-mm-thick (½ in.) plywood or OSB sheathing installed between the wood studs, the horizontal girts and the Neopor® Graphite Polystyrene (GPS) board. The “S” designation stands for seismic, however, the seismic performance evaluation is beyond the scope of this evaluation.
Principle material and accessories

Principle material in the plane of airtightness

  • WALLTITE® CM01 (CCMC 14100-L) spray-applied, polyurethane foam insulation by BASF Canada Inc.
    When installed as part of the designated ABS, WALLTITE® CM01 spray-applied polyurethane foam serves a double function in the wall assembly:
    1. as the principal plane of airtightness of the designated ABS; and
    2. as a thermal insulation.
    The use of the spray-applied polyurethane foam as a thermal insulation is evaluated in 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 Inc. to install the insulation product. The resulting product is a spray-applied polyurethane with an assigned long-term thermal resistance value of 1.82 (m2·K)/W per 50 mm. The colour of the finished product is purple. When the foam insulation serves as the principal component in the BASF Canada Inc. proprietary ABS, it must be installed at a minimum thickness and density, which are specified in the Air barrier system section in the Conditions and limitations section of this evaluation.

  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 density of 39 kg/m3 (also called in-place density), which meets the intent of Subsection 9.25.3., Air Barrier Systems, of Division B of the NBC 2010 and NBC 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 NBC 2015.

The evaluation of HP+ XR and XR-S Series – Air Barrier System is limited to wood-frame construction meeting the requirements of Part 9, Housing and Small Buildings, of Division B of the NBC 2010 and NBC 2015. The air leakage rate of the tested wall assemblies, following structural aging, met 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 assemblies have demonstrated sufficient strength to resist wind loads for use in Part 9 buildings 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 NBC 2015. For applicability of the ABS rating and durability of the components, in wood frame construction beyond Part 9, the stamp of an engineer is required for acceptance by the authorities having jurisdiction (AHJs). See Additional data in the Technical information section of this evaluation.

For ensuring air leakage control and strength in the field, the ABS must be installed in locations where the wind pressure is equal to or lower than the aforementioned wind pressure limits and installed in the field by BASF-trained installers/contractors following the BASF Canada Inc.-specified ABS installation manual entitled HP+ Wall System – Technical Installation Manual (revision date 8 May 2019). Additional construction details and drawings provided in the HP+ Wall System – 3D Field Assembly Guide (version 2019-05-01) for the HP+ XR Series and HP+ XR-S Series must also be followed. Additional field installation requirements are described below in the sections "Air barrier system - field quality assurance" and "Thermal insulation - field quality assurance". A copy of the BASF Canada Inc. installation instructions must be available on the job site at all times during the installation for review by building officials. All installers of WALLTITE® CM01 must present their Caliber certification card upon request by the building official.

See Air barrier system details of this evaluation for examples of the tested wall assemblies.

The product must be identified with the manufacturer’s name and logo, and the phrase “CCMC 14126-R.”

Air barrier system – field quality assurance

When HP+ XR and XR-S Series – Air Barrier System is applied as the designated ABS, BASF Canada Inc. requires that the installer be BASF Canada Inc.-trained and that Caliber conducts the necessary follow-up inspections to ensure that the certified contractors are performing the necessary field quality control (for example, quality check on the application of the transition membrane, sealant and spray foam as per CAN/ULC-S705.2-05, “Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density – Application”).

Caliber conducts periodic audits to ensure:

  • the approved accessories are being used;
  • proper installation of the transition membrane by conducting periodic tension testing as part of the BASF Canada Inc.-specified quality control;
  • proper continuity details and substrate conformance as part of the quality control procedure for the product;
  • proper application of the WALLTITE® CM01 spray-applied polyurethane foam insulation; and
  • the daily work records are maintained for the ABS installation.

All results must be recorded on the Caliber daily worksheet for the HP+™ XR and XR-S Series – Air Barrier System.

Thermal insulation – field quality assurance

When WALLTITE® CM01 is applied as a spray-foam insulation, the material must be manufactured on site by qualified installers trained by BASF Canada Inc. with field inspections carried out by Caliber. Caliber certifies BASF Canada Inc.’s training program and provides follow-up inspections to ensure installations are in accordance with CAN/ULC-S705.2.

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 Caliber certification card and daily work record upon request by the building officials.

Note: the BASF Canada Inc. field quality assurance program calls for periodic audits of the installers. These audits usually consist of random inspections. Some larger projects are subject to mandatory inspections. Building officials may contact BASF Canada Inc. (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 Inc. and the non-conformance is not remedied by the installer, Caliber/BASF Canada Inc. 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 14126-R” and “CCMC 14100-L,” respectively.
