Hotel Guest Unit Doors and Commuication Door Sill requirements

[lunatick]

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.

I don't know of a requirement for a smoke seal at the bottom but you would want something there for sound.

 

[Doorman]

Agree with Lori, it would be desired to seal for sound and light, but not required.

Non-combustible sill at floor?
