Ontario Building Code
Ruling No. 21-04-367 (14382-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 2021-04-12 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(s) is/are 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.
- CL4FIRE Code-96™ Grease Duct Insulation System (CL4)
- CL4Fire RED
The products are a duct/pipe wrap insulation made from calcium, magnesium, and silica encapsulated by a fibre-reinforced foil. The product is 38 mm (1 ½ in.) thick and has a density of 96 kg/m3 (6 lb./ft.3). It is available in rolls of various widths and lengths. It is installed around pipes and ducts, overlapped, taped and or pinned as necessary to provide continuity. All overlapping, sealing materials shall be fully compatible with the product and as recommended by the manufacturer’s written instructions.
Please note that CL4Fire Red and CL4Fire Code 96TM Grease Duct Insulation System (CL4) are identical products just labeled differently.
This evaluation is valid only for products produced at the following plant:

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’s fire ratings and corresponding limitations and installation instructions are based solely on Quality Auditing Institute Ltd.’s (QAI) Building Listing Program under listings F476-1, F476-3, and F476-4.
- The product shall be applied directly to the ductwork and piping in strict accordance with the listed systems referenced above and in the manufacturer’s instructions.
- The maximum service temperature is 120°C.
- The product is limited to a maximum 200 mm outside diameter (8 in.) made from minimum Schedule 10 steel, cast iron or copper for non-fuel, fuel and natural gas piping applications.
- 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 and if additional reinforcement is deemed necessary by the authority having jurisdiction (AHJ), the addition of reinforcing wire mesh can be added over the exterior of any ductwrap installation.
- The phrase “CCMC 14382-R” must be clearly identified on the product’s label and/or packaging.
This evaluation is based on demonstrated conformance with the following criteria:

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.
- 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.
