DSI-FW119 Deployable Fabric Fire Wall

The DSI Deployable Fabric Fire Wall Model DSI-FW119 allows architects to go beyond 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.

The DSI Deployable Fabric Fire Wall consists of two of our DSI Hose Stream Rated Smoke and Fire Curtains mounted back-to-back to create a small light weight package above the ceiling that remains virtually invisible until deployed. The curtains consist of proprietary light weight multi layered fire rated fiberglass/stainless steel fabric and slim steel side guides that can be hidden in the walls.

The DSI Deployable Fire Wall incorporates the cutting-edge technology of our Hose Stream Rated Smoke and Fire Curtain but with the advantage of being tested as a 3-hour fire rated wall assembly. This in turn allows architects more cost-effective options to open space design while still meeting code requirements.
