Firestop board suits high re-penetration applications

June 23, 2006 -- Hilti's CP 675T firestop board is designed for the temporary or permanent sealing of blank openings or through penetrations in fire rated walls.

Based on feedback from electrical and telecommunications professionals, Hilti, Inc. has developed its CP 675T firestop board, designed for the temporary or permanent sealing of blank openings or through penetrations in fire rated walls.

The firestop board can be used alone for low re-penetration applications, or with the company's FS 657 firestop blocks for high re-penetration applications and large openings.

According to the company, the "fiber-free, solvent-free, ready to use" CP 675T firestop board can be surface mounted for low re-penetration applications. Because it's easy to cut and can be installed without power tools, the product provides up to 50 percent labor savings over competitive firestopping composite sheets, contends the company.

Also, for locations where telecommunications and electrical applications are modified on a regular basis, such as central offices within telecom facilities, computer/data centers, commercial facilities, health care facilities, and laboratories, the CP 675T can be frame mounted for quick and easy re-penetration. The company says that the frame mounted option allows contractors to use the CP 675T with the company's FS 657 firestop blocks for "remarkable" flexibility, easy re-penetration, and cable mining from one side.

As a flexible, UL-listed means of sealing large openings (3 x 4 ft. and smaller), contractors can frame-mount the firestop board and firestop blocks, then use a t-bar to split large openings into smaller compartments, suggests the company. This option allows cables, cable bundles, and cable racks to be quickly and easily added or removed.

Hilti also offers the CP 658T firestop plug, an intumescent plug suitable for sealing cored or round holes in gypsum and concrete block walls and concrete floors. The plug is re-usable, re-penetrable, and comes ready-to-use.
