  • The wall assemblies described in the sound transmission class (STC) rating table must be used in dwelling units that meet Part 9, Housing and Small Buildings, of Division B of the NBC 2015. Where the wall assemblies are used as a separating wall between two dwelling units, the wall assemblies must be installed with adjoining construction (floor/wall/ceiling assembly) that meets the prescriptive requirement details of Article 9.11.1.4., Adjoining Constructions, of Division B of the NBC 2015.
  • The wall assemblies must have a sound transmission class (STC) rating of at least 50 as required by Clause 9.11.1.1.(1)(b), Required Protection, of Division B of the NBC 2015. Where a dwelling unit is adjacent to an elevator shaft or a refuse chute, the separating wall assembly must have an STC rating of at least 55 as required by Sentence 9.11.1.1.(3) (required protection for construction separating a dwelling unit from an elevator shaft or refuse chute), of Division B of the NBC 2015.
  • For fire performance, a ULC Listing showing that the sound-insulating assemblies specified in the sound transmission class (STC) rating table meet the fire-rating requirements of the NBC 2015 is required in buildings where the NBC 2015 requires a fire-resistance rating for wall assemblies. Ratings must be determined in accordance with CAN/ULC-S101-14, “Fire Endurance Tests of Building Construction and Materials.” Users of this Evaluation Report must request a copy of the ULC Listing from Building Products of Canada Corp.
  • The STC values published in the sound transmission class (STC) rating table are valid for the wall configurations shown in the table and the additional construction details described in the referenced notes.
  • The wall assemblies’ components presented in table Sound transmission class (STC) rating (glass fibre insulation batt, gypsum board, wood studs and steel studs) and their installation must comply with the requirements of the NBC 2015 and the Building Products of Canada Corp.’s installation manual.
  • The wall assemblies described in the sound transmission class (STC) rating table that include steel studs are for non-loadbearing applications.
  • The product must be installed by an informed and knowledgeable installer.
  • The product must be identified with the phrase “CCMC 13475-R.”

Performance requirements

Acoustical performance

The acoustical performance of five wall assemblies enclosing the "Enermax (acoustical insulation)" panel has been evaluated in terms of airborne sound transmission loss. The airborne sound transmission measurements have been conducted in accordance with the requirements of ASTM E 90-09, “Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements.”

Based on these measurements, the STC rating for the five wall assemblies was determined in accordance with ASTM E 413-10, “Classification for Rating Sound Insulation,” and published in sound transmission class (STC) rating table

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
