CL4 Grease Duct Insulation System

Grease Duct Insulation System is rated for 229 mm (9 in.) clearance from duct to combustibles using one layer.  CL4 is rated for 0 mm clearance from the outside of the insulation to combustibles using one layer of CL4Fire Code 96TM on the inside or outside layer and one additional layer of CL4 (Red or Code 96) for a total thickness of 76 mm (3 in.) overall.

All of the relevant requirements within NFPA 96, “Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations,” must be satisfied to demonstrate compliance for this evaluation.

Installation specifics for the CL4 Grease Duct Insulation System

  1. The product.
  2. 23 cm (9 in.) minimum clearance from duct to combustibles when 1-layer of CL4Fire Code 96TM is installed.
  3. 0 mm clearance allowed to combustible materials such as wood when 2-layers (76 mm thickness) of CL4 is installed.
  4. 23 cm (9 in.) minimum clearance from duct to combustibles such as wood when 1 layer of CL4Fire Code 96TM is installed. 
  5. Inside duct.
  6. Steel banding.

Notes:

  • Single 38 mm (1 ½ in.) thick layer installation of CL4Fire Code 96TM wrap allows for minimum 23 cm (9 in.) clearance from ductwork to combustibles with 76 mm (3 in.) overlaps at all single layer installation joints.
  • Two 38 mm (1 ½ in.) layers of insulation are required for 0 mm clearance from the first layer using CL4 with tightly butted seams and the outer layer with CL4 installed with tightly butted seams staggered a minimum of 152 mm (6 in.) from the first layer seams. The exterior layer of CL4 wrap must exceed the size of the interior layer only if CL4 is installed on the interior layer. Butted seams on the first layer of the wrap must always be covered with the second layer, which is required to overlap by a minimum of 76 mm (3 in.).
  • CL4Fire Code 96TM is to be installed continuously along the ductwork in the same manner as a gypsum shaft. Intermittent installation with a single layer is prohibited.  Only the second layer may be intermittent based on clearance requirements as outlined in figure 3.
  • As required by NFPA 96, field-applied and factory-built grease duct enclosures shall provide mechanical and structural integrity, resiliency, and stability when subjected to expected building environmental conditions, duct movement, under general operating conditions, and duct movement as a result of interior and exterior fire conditions. These conditions should be reviewed prior to installation.
  • Install firestops and access panels as outlined in the QAI listing F476-3. The reduced clearance access panel requires only 2 layers of CL4 insulation as per the manufacturer’s instructions.

CCMC recognition

The Canadian Construction Materials Centre (CCMC) assesses compliance with Canadian building, energy and safety codes. We are the only construction code compliance service supported and operated by the Government of Canada. Trusted by over 6,000 regulators across Canada.

Most Canadian authorities having jurisdiction (AHJs) consider CCMC product assessments acceptable as evidence for product approval.

CCMC assessments are recognized by construction authorities across Canada:

The CCMC provides code compliance assessments to Canadian code requirements, consulting nationwide with construction regulators to elicit regional variations in code requirements as well as provincial and local interpretations. Users are advised to review the technical information presented in CCMC assessments when making approval decisions. Learn more about how the CCMC provides a unique service for Canada.

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

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:
