Introducing DSI-FW119 Deployable Fabric Fire Wall
A vertical-acting fabric firewall that was tested for 3 hours.
The DSI Deployable Fabric Fire Wall Model DSI-FW119 allows architects to exceed the maximum 25% fire barrier opening penetration restriction. (IBC Section 707.6) Typical overhead or side-acting opening protectives with a fire-resistance rating fall into this limitation.
However, with an ASTM E119/ UL263 rating, the DSI Deployable Fabric Fire Wall is considered a wall and, therefore, meets the exception (Exception 3) and is not limited to this rule.
IBC Section 707.6
Exception 3: Openings shall not be limited to 156 square feet (15 m2) or an aggregate width of 25 percent of the length of the wall where the opening protective has been tested in accordance with ASTM E119 or UL 263 and has a minimum fire-resistance rating not less than the fire-resistance rating of the wall.
