F Dear Mr. Clark:
This letter is in response to your fax dated 4/20111 (attachment 'A") r acuestinry a code interpretation for the above
mentioned project. With that fax were tyw) non-scale copies of piopcssed floor plans
°? You had two questions: ��•
1) Can you place a 3 -hour fire- resiMence -•ated door wrath 3 -hour rated giaring in an e;.ist :ng 3 -hour fire-
resistance4ated fire wa0
2) Does the addition of doers across a rated coridor tc divide 'he corridor into separate sect fns need to he
20 minute fire resistance - rated?
i
i My conclusions are:
1) Table 715.4 of the 2009 NC Building Code (NCBC) indicates that a 3 -hour door is acceptable in a 3 -hour
Fire wall. Section 715.5 - F1re- Protectlor -Rated Gtazi. ^5 indicates that compliance with Sect on 795.4.5 is
required for the glazing. Section 715.4.6.1 - Size Limitations indicates ii Exception #1 that "Fire -
F7h.t6ctior -rated gla7irxg i r, Are doors l ocated in fire walls S hari be prohiNted except 'hat v ihere. serving as
a '7orizoiafal exit, a se,Yclasiny swix�irg door .shat! be , :yen. niltcd tv have P vision panet o` lint . ore than
100 cquars inches without a rlirrension exceeding 10 inches" Only such doors t ^at are used as a
horizontal exit: as described in Section , '022 Tray have glazing and then the size is fmited to In0 s;uare
inches.
2 The cote does not indicate a requirement for a rated door in a .%rrri jor %vhere t ie rloor i- usec' ar ly to 7
- subdivide the corridor into sections. As lo ng as the corridor cor; Is Xll irIUCLS on either aide of the
door then the door may be unrated.
I trust this addresses your concerns. If I can be of further assistance. do not hesitate to contact Me.
