/ This specification was created by Vicwest to assist designers. It should be reviewed and modified as required to suit individual project conditions. / Page 1 of 5[r1]The NBCC limit for air leakage is 0.3 L/s per sq. m. (0.06 cfm/sq. ft.)at a pressure difference of 75Pa
[r2]This applies to projects where, by NBCC, is categorized as Non-Combustible Construction.
On multistorey applications, when applying combustilbe components in a non-combustible construction building, CAN/ULC-S-134 is required to certify the material. In Ontario, the limiting height for the application combustible materials in non-combustible construction is 6 storeys (if sprinklered throughout)
