CAN/ULC-S704-03

1. SCOPE 1.1 This Standard covers requirements and test methods for closed cell polyurethane and polyisocyanurate foam thermal insulation in the form of flat rigid boards covered on both sides with a facing material and primarily intended for use in applications where the continuous use temperature is within the range -60oC to +93oC. These rigid boards are not intended to be used as structural panels. The Standard covers products made with various facing materials, which impact some physical characteristics. Products manufactured to this Standard are intended for use as thermal insulation in building construction. 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 product made using fibreboard, perlite board, gypsum board, oriented strandboard, or any other rigid board, on one or both sides (users are referred to ASTM C 1289- 02).
