Scope
These Evaluation Listings apply to closed-cell polyurethane and polyisocyanurate foam thermal insulation in the form of flat rigid boards covered on both sides with a facing material. The rigid boards are intended for use as thermal insulation in building construction. The continuous use temperature is within the range of –60°C to +93°C.
These rigid boards are not intended to be used as structural panels.
The standard referenced below provides a basis for evaluating products made with various facing materials, which has an impact on some physical characteristics. This standard covers only products in which the facing material has been bonded to the foam core in the original foam manufacturing process.
This standard does not apply to products made using fibreboard, perlite board, gypsum board, oriented strandboard, or any other rigid board, on one or both sides.
The proponent has demonstrated that the product meets the requirements of at least one of the following standards:
- CAN/ULC-S704-03, “Thermal Insulation, Polyurethane and Polyisocyanurate, Boards, Faced”
- CAN/ULC-S704-11, “Thermal Insulation, Polyurethane and Polyisocyanurate, Boards, Faced”
Products manufactured to this standard are classified as Type 1, 2 or 3 on the basis of their physical properties and Class 1, 2 or 3 on the basis of water vapour permeability. Typically, Type 1 products are used in wall applications, whereas Type 2 and 3 products are used in roofing applications.
