Ontario Building Code

Ruling No. 15-03-324 (13510-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2015-01-05 pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.


The above opinion is based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.

  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 the printed side facing outward and must be protected from exposure to ultraviolet (UV) radiation from the sun within 60 days,
    • in accordance with Article 9.27.3.3., Insulating Sheathing in lieu of Sheathing Membrane, of Division B of the NBC 2015, and the manufacturer’s current instructions; and
    • 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:
