Weathertightness and durability requirements need to be met when designing or altering school buildings. As a board of trustees, you must make sure your project manager and designer are aware of these requirements.

Designing buildings for weathertightness and durability

When designing or altering a building, make sure your project manager and designer know about our Weathertightness and Durability Requirements [PDF, 3 MB]. Our requirements set out our minimum standards for building construction, which is a higher standard than the Building Code. They:

  • define products that cannot be used on school building projects
  • list products that must be peer reviewed if used
  • include requirements to ensure the durability of certain materials when used in specific locations.
