PART 2 - PRODUCTS

2.1 MANUFACTURER

A. HILTI Firestop Systems, Inc.

2.2 FIRESTOP SYSTEMS

A. Use either factory built (Firestop Devices) or f ield erected (through-

Penetration Firestop Systems) to form a specific bu ilding system maintaining required integrity of the fire barrier and stop the passage of gases or smoke.

B. Through-penetration firestop systems and firesto p devices tested in accordance with ASTM E814 or UL 1479 using the "F" or "T" rating to maintain the same rating and integrity as the fire barrier being sealed. "T" ratings are not required for penetratio ns smaller than or equal to 100 mm (4 in) nominal pipe or 0.01 m 2 (16 sq. in.) in overall cross sectional area.

C. Products requiring heat activation to seal an op ening by its intumescence shall exhibit a demonstrated ability t o function as designed to maintain the fire barrier.

D. Firestop sealants used for firestopping or smoke sealing shall have following properties:

1. Contain no flammable or toxic solvents.

2. Have no dangerous or flammable out gassing durin g the drying or curing of products.

3. Water-resistant after drying or curing and unaff ected by high humidity, condensation or transient water exposure.

FIRESTOPPING 07 84 00 - 3

4. When used in exposed areas, shall be capable of being sanded and finished with similar surface treatments as used on the surrounding wall or floor surface.

E. Firestopping system or devices used for penetrat ions by glass pipe, plastic pipe or conduits, unenclosed cables, or oth er non-metallic materials shall have following properties:

1. Classified for use with the particular type of p enetrating material used.

2. Penetrations containing loose electrical cables, computer data cables, and communications cables protected using f irestopping systems that allow unrestricted cable changes witho ut damage to the seal.

3. Intumescent products which would expand to seal the opening and act as fire, smoke, toxic fumes, and, water sealant.

F. Maximum flame spread of 25 and smoke development of 50 when tested in accordance with ASTM E84.

G. FM, UL, or WH rated or tested by an approved lab oratory in accordance with ASTM E814.

H. Materials to be asbestos free.

J. Engineering Judgements - For situations where cu stom drawings for firestopping assemblies are required to accommodate particular conditions/applications not identified in the HILTI Firestop Systems

Installers Guide U.S. Volume 12, contractor to comp lete documentation on page 270 of the guide to request an engineering judgement from

HILTI. Completed form(s) to be faxed to 918-254-167 9.

2.3 SMOKE STOPPING IN SMOKE PARTITIONS

A. Use silicone sealant in smoke partitions as spec ified in Section 07 92

00, JOINT SEALANTS.

B. Use mineral fiber filler and bond breaker behind sealant.

C. Sealants shall have a maximum flame spread of 25 and smoke developed of

50 when tested in accordance with E84.

D. When used in exposed areas capable of being sand ed and finished with similar surface treatments as used on the surroundi ng wall or floor surface.
