Product information

Product name

Legerclad (Composite EPS Board and Sheathing Membrane)

Product description

The product is a Type 2, preformed moulded, expanded polystyrene rigid insulation panel (CCMC 12836-L). The panels are plant-laminated to a spun-bonded olefin sheathing membrane (Typar^® CCMC 12892-R made by Fiberweb, LLC) with THERMOBOND JPS70300, a hot melt adhesive, applied in 0.51 mm thicknesses every 7.6 mm. The panels are commonly 1 219 mm × 2 438 mm or 1 219 mm × 2 743 mm and are available in 25 mm to 76 mm thicknesses. A sample of the product is shown in the figure below.

Manufacturing plants

This evaluation is valid only for products produced at the following plants:

Pointe-Claire, Québec, Canada

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.

The product must be installed:

- with a minimum 10 mm air space between the sheathing membrane and the cladding, unless the cladding has been deemed to not require an air space (e.g., deemed by the CCMC or by building officials based on past cladding performance).
Thicknesses greater than 50 mm and having a water vapour permeance less than 60 ng/(Pa·s·m²) must comply with Article 9.25.5.2., Position of Low Permeance Materials, of Division B of the NBC 2015.
Sheathing tape (CCMC-evaluated) must be used to seal all joints.
A concealed air space that is more than 25 mm wide must contain proper fire blocking, in accordance with Subsection 9.10.16., Fire Blocks, of Division B of the NBC 2015.
When sheathing is required, the product must have a minimum thickness of 38 mm as per Table 9.23.17.2.A. of Division B of the NBC 2015.
Use of this product as part of an air barrier system is covered under a separate the CCMC Evaluation Report (see CCMC 13519-R).
The product must be clearly identified with “CCMC 13510-R” and the name of the manufacture or logo.

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:

The NRC has evaluated the material, product, system or service described herein only for those characteristics stated herein. The information and opinions in this evaluation are directed to those who have the appropriate degree of experience to use and apply its contents (i.e., AHJs, design professionals and specifiers). This evaluation is only valid when the product is installed in strict compliance with the stated conditions and limitations of evaluation and the applicable local building code. In circumstances where no applicable local building permit is issued and that no confirmation of compliance ‘for use in the intended field application’ is undertaken, this evaluation is null and void in all respects. This evaluation is provided without representation, warranty, or guarantee of any kind, expressed, or implied, and the NRC provides no endorsement for any evaluated material, product, system or service described herein.

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.
