The National Building Code of Canada is a model code whose principal objective is to set out requirements and criteria to provide a minimum acceptable level of health and safety for occupants of buildings across Canada. As a model code, the NBC has no legal status unless adopted or adapted by an authority having jurisdiction. Through adoption and adaptation, it serves as the basis for all building regulation in Canada.
Contents of the NBC In addition to the technical requirements addressing the subjects outlined previously, the NBC provides: ??general statements of application ??definitions of words and phrases that have special meaning in the context of the Code ??references to climatic information, and ??requirements for design information and design review to indicate compliance with the technical requirements.
National Housing Code of Canada The National Housing Code of Canada 1998 and Illustrated Guide contains all the code requirements and best practice examples to help you avoid common problems and build houses with success. This code is intended to help builders and building officials, architects, engineers, developers, designers and other industry representatives apply the requirements of the National Building Code of Canada (NBC) to detached, semi-detached and row houses. The Housing Code concentrates on requirements identified in Parts 1, 2, 3, and 9 of the NBC using plain language and self-explanatory illustrations throughout. The Illustrated Guide portion deals with a wide spectrum of building issues including foundations; floor framing; fire resistance and sound transmission; roofing; windows, skylights, and doors; mechanical systems; plumbing and electrical facilities; and garages, carports, and decks Published by the National Research Council Canada's Institute for Research in Construction, 1998.

There has been much discussion since the 1950¡¯s regarding how to provide a separation between interior and exterior environments in the cold Canadian climate. Part 5 of the 1985 National Building Code, ¡°Wind, Water and Vapour Protection¡±, has outlined the minimum requirements for this separation. Section 5.3.1. discusses air barriers and their location in the building envelope. Reducing air leakage by incorporating a continuous air barrier in the building envelope design is fundamental in the successful performance and durability of the building envelope. There are a variety of approaches which have been used to achieve airtightness in the building envelope, with some being more successful at fulfilling this requirement than others. Part 5 does not restrict approaches to airtightness, but states that ¡°the assembly shall be designed to provide an effective barrier to air exfiltration and infiltration, at a location that will prevent condensation within the assembly¡¡¡±.
