![]() ![]() ![]() Once filled with concrete, the ICF units remain in place as the thermal insulation for the resulting cast-in-place concrete wall of uniform cross-section and thickness. This Standard specifies the requirements for stay in place, modular expanded polystyrene (EPS) Insulating Concrete Form (ICF) units. Standard for Flat Wall Insulating Concrete Form (ICF) Units – Material Properties The standard also specifies the minimum thickness of concrete required in ICF walls to ensure adequate fire resistance.Ĭompliance with CAN/ULC-S717.1 is typically required by building codes and regulations in Canada, and is important in ensuring the safety and fire-resistance of buildings constructed with ICFs or other insulation materials. It includes tests for flame spread, smoke production, and fire resistance, and sets specific criteria that materials must meet to be approved for use in various building applications.įor ICFs specifically, CAN/ULC-S717.1 requires testing of both the foam and concrete components of the system to evaluate their individual fire performance. This standard outlines the testing procedures and requirements that insulation materials must meet to be considered fire-resistant. The standard is developed by the Canadian Standards Association (CSA) and Underwriters Laboratories of Canada (ULC). Building officials and inspectors use the codes to ensure that new construction meets minimum safety standards and to issue building permits and certificates of occupancy.ĬAN/ULC-S717.1 is a Canadian standard for testing and evaluating the fire performance of various types of insulation materials, including insulating concrete forms (ICFs). The IBC, on the other hand, is intended for adoption by governments for commercial and multi-family residential construction, as well as high-rise buildings.īoth codes are updated every three years to reflect new technologies and building practices, and they serve as a baseline for building safety standards across the United States. It applies to one- and two-family dwellings, as well as townhouses that are not more than three stories in height. The IRC is intended to be adopted by local and state governments as a basis for their own building codes. The codes cover a wide range of topics related to building safety, including structural design, fire safety, plumbing, mechanical systems, and energy efficiency. The International Residential Code (IRC) provides standards for residential construction, while the International Building Code (IBC) provides standards for commercial construction. The IRC and IBC are both model building codes developed by the International Code Council (ICC). ![]()
