CSA B272-93 (R2000) PDF Download

CSA B272-93 (R2000) standard establishes the minimum requirements for roof vent flashings that are constructed in a factory setting. These flashings are designed to create a permanent weather seal between the flashing and the vent pipe without the need for additional sealing materials. However, it is important to note that flashings that are built on-site are not covered by this standard.

The standard covers various aspects, including material requirements, quality of work, and performance criteria related to weather resistance. It aims to ensure that the flashings meet the necessary standards and provide reliable protection against the elements. Additionally, the standard outlines guidelines for marking the product to indicate compliance with the specified requirements.

It is worth mentioning that the standard primarily uses SI (metric) units as the standard measurement system. However, for informational purposes, some values are also provided in parentheses using different units of measurement.
