  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 evaluation of this product was limited to above-grade wall cavity insulation for Part 9 construction.
  • Due to the decreased density of this product (compared with CAN/ULC-S701 compliant EPS), it may only be used as an above-grade wall cavity insulation material where the material is not intended to resist compressive stress (i.e., not intended for use as a sheathing material or below grade exterior applications).
  • The material must be installed according to the manufacturer’s installation instructions and must be mechanically fastened to a substructure by cap screws.
  • The product must be clearly identified on the product label as an above-grade wall cavity insulation only, and bear the CCMC number referenced above.
