[CCMC evaluation requirements] CAN/ULC-S703-09, Type 1
This document provides a summary of the minimum requirements imposed by the Canadian Construction Materials Centre (CCMC) for all evaluations based on the below criteria document. Additional requirements may be imposed by the CCMC when necessary for a particular evaluation, and are detailed in the individual evaluation.
Criteria document
| Number | CAN/ULC-S703-09, Type 1 |
| Title | Standard for Cellulose Fibre Insulation for Buildings |
| Document | Standard |
| Publisher | ULC Standards |
Scope
These evaluations apply to treated, wood-based cellulose fibre intended for use as thermal insulation (cellulose fibre insulation (CFI)) in new and existing buildings. The continuous use temperature range is within –60°C to 90°C.
The standard describes two types of CFI. They are defined in CAN/ULC-S703 as follows:
- Type 1 is intended for pneumatic application into open areas with slopes up to 4.5:12, or injection application into closed cavities, such as walls, floors and cathedral ceilings. Type 1 may also be manually applied (poured application).
- Type 2 is intended for spray application with water or liquid adhesive into open areas regardless of slope (e.g., attics), exposed surfaces (e.g., walls or ceilings) and/or into any open cavity (e.g., wall, floor or ceiling cavities) that may be closed later. This product may also contain internal binders to increase the adhesive/cohesive capabilities of the sprayed fibres in order to reduce settlement and/or ensure it remains in place.
The following evaluation requirements apply to a Type 1 product.
Material requirements
The evaluation holder must demonstrate that the product meets the following requirements (additional requirements may be imposed by the CCMC when necessary, and are detailed in the individual evaluation):
| Property | Unit | Requirement |
|---|---|---|
| Thermal resistivity | m·K/W | ≥ 18.5 |
| Open flammability | W/cm2 | ≥ 0.12 |
| Open flammability permanency | W/cm2 | ≥ 0.12 |
| Smoulder resistance | % | ≤ 15 |
| Moisture vapour sorption | % | ≤ 20 |
| Corrosiveness | _ | No perforations |
| Fungi resistance | _ | Fungal growth shall not exceed that of the comparative item. |
| Separation of chemicals | % | ≤ 1.5 |
| Design density | kg/m3 | As determined |

Installation requirements
The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:
- do not contravene the National Building Code of Canada, or any provincial or territorial building codes; and
- meet the requirements of CCMC minimum documentation requirements.
Manufacturing requirements
The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:
- is operated under a documented quality system; and
- meets the minimum requirements of the CCMC minimum documentation requirements.
Labelling requirements
The CCMC requires that evaluation holders ensure that product labels:
- reference the associated CCMC number or mark; and
- meet the requirements of CCMC minimum documentation requirements.
In addition, the standard requires that each bag of insulation be identified with the following information:
- manufacturer’s name and address;
- trade name of the product;
- generic product name;
- material type and subtype; (e.g., Type 1 (open spaces), Type 2 (closed cavities)(1), etc.);
- package mass;
- standard number CAN/ULC-S703;
- day/month/year of manufacture or traceable code number;
- coverage table(s) providing the information described in the appropriate subsection of the standard; and
- cautionary note as follows:
- “CAUTION: Maintain building, electrical, gas and oil safety code required clearances between the insulation and heat-emitting devices, such as fuel-burning appliances, chimney pipes, ducts and vents to these appliances (at least 50 mm) and recessed light fixtures (at least 75 mm) unless approved for insulation contact.”
(1) Cavities that are open during the installation of insulation (e.g., wall, floor or ceiling cavities) and may be closed later.
