CASE 1: Vertical Coiling with Complying Swing Egress Door(s)
Complying with Table 508.4 and providing fire barrier walls to separate occupancies can be limiting to the design. Also, using non-separated provisions to eliminate restrictive fire barrier walls becomes extremely costly due to added fire and life safety requirements that affect the entire structure.
The use of wide span opening protectives enables occupancy separation without compromising open and spacious design. In this case study a simple deployable separation prevents the overall structure from being subject to the most restrictive provisions of non-separated use.
