Firestop with Actifoam withstands three-hour fire test
Multi-cable and Cable-tray Firestop PenetrationsCSD FIRSTO® firestops are designed to seal multi-cable and cable tray penetrations of fire-rated walls or floors. FIRSTO® utilizes a metal frame that encompasses the entire cable run, cable tray with cable or bus duct at the point of penetration. Fire-resistant cellular rubber inter-layered with intumescent pads provides a U.L. classified firestop for up to four hours.
10 reasons to count on CSD FIRSTO for your firestop needs
Typical CSD FIRSTO Firestop Unit Construction
The CSD FIRSTO system is made up of three basic components:
The metal frame is attached to the wall or floor and holds the other materials in place before, during and after a fire. To perform in all types of environments, the frame can be made in enameled (painted steel), galvanized steel, or 304 stainless steel. These frames can be opened and closed. The frame is lined with a blue, fire-resistant rubber (see our FRR/HF MSDS Sheet) that performs two functions. First, it adds structural support to the frame during a fire. Second, it insulates the yellow intumescent pads, helping to direct their expansion during a fire. The yellow intumescent pads are the active ingredient in our system. These soft, sponge-like pads expand 8 to 10 times their size when exposed to temperatures 400°F or above (see our CSD-F MSDS Sheet). This expansion is gradual, and the pads maintain their seal around the penetrating items for the duration of the fire. These pads are easily cut to fit around any large cable, cabletray, or duct that passes through the CSD unit. If a watertight or airtight seal is needed, we recommend applying a thin coat of our FIWA caulking material (see our FIWA MSDS Sheet) over the exposed edge of the pads. This intumescent silicon-based elastomer provides a durable weather-resistant seal that is unaffected by most chemical environments.
