Product information

Product name

WALLTITE® XL01

Product description

“WALLTITE® XL01” is a spray-applied, rigid polyurethane foam of medium density that has a closed-cell structure. The foaming system consists of two components that must be labelled with “CCMC 14230-R” and the following information:

Isocyanate (Component A): “Elastospray® 8000A”; and
Resin (Component B): “WALLTITE® XL01.”

The two components are mixed on-site by a BASF Canada Inc.-qualified installer (see Section 3.2) with fixed-ratio positive displacement equipment.

This product is referred to as a ‘high-lift’ spray polyurethane foam whereby a thick layer of “WALLTITE® XL01” can be applied in a single pass. The product is installed at a maximum nominal thickness of 127 mm and a minimum nominal thickness of 50 mm. This installation method differs from the method described in CAN/ULC-S705.2-05, “Standard for Thermal Insulation – Spray Applied Rigid Polyurethane Foam, Medium Density – Application,” which specifies a 50-mm maximum nominal thickness for spray foam installed in a single pass.

The final cured product has a density of 32.25 kg/m³and is available in the following colour:

Dark purple

At 50-mm thick, the design long-term thermal resistance (LTTR) value is 1.87 (m²·K)/W. See physical properties of the product for estimated LTTR values at higher thicknesses.

The product is available in winter grade and regular grade formulations.

CCMC’s compliance opinion is bound by “WALLTITE® XL01” being used in accordance with the conditions and limitations set out below.

The cured polyurethane foam must have a minimum nominal thickness of 50 mm and a maximum nominal thickness of 127 mm. Any product sprayed to a thickness greater than 140 mm (maximum nominal thickness plus a field safety margin of 13 mm) must be removed from the substrate immediately after application and the substrates sprayed again. IMPORTANT: spraying to a thickness greater than 140 mm may result in spontaneous combustion or poor foam quality.
The application of the foam in multiple passes is beyond the scope of this evaluation.
The polyurethane foam can be applied on the substrates listed under physical properties of the product. Substrates must be clean, dry, and free of grease, frost, dust, rust and other contaminants that may affect the adhesion performance of the foam to the substrate.
Below-grade (exterior side of foundation wall) and attic applications are beyond the scope of this evaluation.
As required in Article 9.25.2.3., Installation of Thermal Insulation, of Division B of the NBC 2010 and NBC 2015, the insulation shall have a reasonably uniform insulation value over the entire face of the insulated area.
The assessment of the fire hazard-peak temperature reached during foam application is only valid for the tested substrates under material temperature requirements due to exothermic reaction and for foam applied in a single pass with a maximum nominal thickness of 127 mm.
The peak temperatures of the thick single pass may affect the performance and durability of materials and equipment in contact with the foam (such as ducts and pipes). The performance of such components is beyond the scope of this evaluation. The measured maximum temperature of the foam while curing is specified under material temperature requirements due to exothermic reaction.
The interior side of the polyurethane foam insulation must be covered with an approved thermal barrier as per:
- Article 3.1.4.2., Protection of Foamed Plastics, of Division B of the NBC 2010 or NBC 2015;
- Article 3.1.5.12., Combustible Insulation and its Protection, of Division B of the NBC 2010;
- Article 3.1.5.15., Foamed Plastic Insulation, of Division B of the NBC 2015; or
- Article 9.10.17.10., Protection of Foamed Plastics, of Division B of the NBC 2010 or NBC 2015.
When applicable, the exterior surface of an exterior wall containing this insulation shall be designed in accordance with Section 9.10, Fire Protection, of Division B of the NBC 2010 or NBC 2015, or Section 3.2, Building Fire Safety, of Division B of the NBC 2010 or NBC 2015. The product shall not be used in exposed interior or exterior locations.
The insulation must be kept away at least 75 mm (or as required by building regulations and safety codes) from heat-emitting devices (such as recessed lighting fixtures and chimneys). The insulation shall not be used inside electrical outlets or junction boxes.
For retrofit construction, the time to occupancy is 25 hours when installed with the requisite ventilation of the segregated retrofit area as per CAN/ULC-S705.2. Additional details are provided in Note 3 in physical properties of the product.
When the product is installed in an exterior insulation sheathing-type application, the low air and water vapour-permeance value of the product requires that the wall assembly conform to Table 9.25.5.2., Ratio of Outboard to Inboard Thermal Resistance, of Division B of the NBC 2010 or NBC 2015.
The product must not be installed after the expiry date printed on the label of each container. The product has a shelf life of four (4) months from the date of manufacture.
The substrate temperatures are −15°C to 5°C for the winter grade formulation and 0°C to 40°C for the regular grade formulation. The appropriate formulation shall be chosen for the specific temperature conditions of application in consultation with BASF Canada Inc.
The installation of the product must:
- conform to the general requirements of CAN/ULC-S705.2-05,
- comply with the manufacturer’s specific installation instructions for their proprietary high-lift product
- be performed by a qualified installer, and
- meet all conditions and limitations in this evaluation.
The continuous in-service temperature of the insulation must not exceed the range of −60°C to 80°C. The building envelope in which this product is installed must conform to the requirements of Division B of the NBC 2010 or NBC 2015 for vapour barrier, air barrier and dampproofing (interior below-grade walls).
The product must be protected from ultraviolet radiation within 90 days of installation.
The installation must be carried out by certified installers in accordance with the manufacturer's instruction manual, which must be available at the job site at all times during the installation for review by the building official.

Technical information

This evaluation is based on demonstrated conformance with the following criteria:

Evaluation requirements
Criteria number	Criteria name
CCMC-TG-072119.06-15	CCMC Technical Guide for Spray-Applied Rigid Polyurethane Foam Insulation – Single Pass Medium Density
CCMC-TG-072119.06-20	CCMC Technical Guide for Spray-Applied Rigid Polyurethane Foam Insulation – Single Pass Medium Density

The Report Holder has submitted technical documentation for CCMC’s evaluation. Testing was conducted at laboratories recognized by CCMC. The corresponding technical evidence for this product is summarized below.

The following were the key performance requirements for the evaluation:

Material qualification:
- Foam basic properties per CAN/ULC-S705.1 requirements except for the sample preparation. Samples were sprayed at the maximum nominal thickness of 127 mm using a single pass instead of two passes of 30-mm each nominal thickness as specified in CAN/ULC-S705.1. Foam application of regular formulation at 23°C was used for testing as required in CAN/ULC-S705.1.
- Key physical properties in high- and low-temperature applications.
Adhesion performance: Foam adhesion strength to different substrates (the manufacturer-selected substrates were wood, gypsum, and concrete). Foam application of regular formulation at high surface temperature was considered a worst-case scenario.
Foam uniformity: Foam cells uniformity when sprayed in different wall cavity dimensions. Foam application of regular formulation at high surface temperature and at maximum nominal thickness was considered a worst-case scenario.
Fire hazard: Maximum temperature achieved in the foam due to exothermic reaction (high internal temperature generated while curing). Foam application of winter grade formulation at lowest surface temperature was considered a worst-case scenario by the manufacturer.

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:

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.
