High rise buildings that are 410 feet tall must have an SFRM bond strength of at least:

In high-rise buildings of 410 feet in height, the bond strength requirement for Spray-Applied Fire-Resistive Material (SFRM) is critical for ensuring structural integrity and fire safety. The specified bond strength of at least 430 psf (pounds per square foot) reflects the performance standards necessary to withstand various stresses and potential impacts during fire events.

This requirement is essential because high-rise structures are exposed to specific conditions, including higher wind loads and structural movement, which necessitate robust fireproofing measures. An adequate bond strength helps ensure that the SFRM remains adhered to the underlying materials, providing effective fire resistance and fulfilling safety regulations.

Understanding this bond strength requirement is vital for architects, engineers, and inspectors who work on fireproofing installations in high-rise buildings, as it directly impacts the design and safety of the structure.
