What would trigger any requirements for sealing the door at the sill for these two different instances.

Unit to Unit 715.4.2

Unit to Corridor. 715.4.3

715 I see many things, but not directly about the parts of the door.

except by reference to NFPA and UL.

Any help?
 
I found a site with NFPA 105 available. Assuming it is current or current for use with IBC 2006. It would appear that the Door in question, which isn't a Smoke Door, doesn't require a seal

4.5.6 The opening between the bottom edge of the smoke door and the sill when the door is in the closed position shall not be

required to be provided with a means to seal the opening.
 
Agree with Lori, it would be desired to seal for sound and light, but not required.

Non-combustible sill at floor?
 
= = =

From the 2013 Edition of NFPA 80 - Fire Doors And Other

Opening Protectives, Section 4.8.2 - Sills,

...Sub-section 4.8.2.1:"In buildings with noncombustible

floors, a sill shall not be required, provided the floor structure

is extended through the door opening."

Sub-section 4.8.2.2:"In buildings with combustible floors or

combustible floor coverings, a sill shall be required if the floor

structure is extended through the door opening, as combustible

floor construction shall not be permitted to extend through the

door opening."

Sub-section 4.8.2.3:"Door openings required to be protected

by 1/2 hour or 1/3 hour rated fire protection for door assemblies

shall be exempted from the requirements of [ Section ] 4.8.2.2."
