3. Features:a. Fire-Rated: The fire retardant, impregnated foam provides a 2 hr horizontal fire

rating in accordance with UL 2079.b. Watertight: Installed with tensionless bellows; when installed with an optional

silicone bead on the weather face, maintains a watertight seal.c. Sound Attenuation: Minimizes sound transfer which can occur at expansion

joints and wide openings. Tested to ASTM E90.d. Non-Invasive Anchoring: No drilling or modifying the substrate required.

1) This includes embedded pins, anchors, screws, bolts, tracks, rails, flanges or cover plates.

2) The system is secured to the joint substrate by means of the internal recovery force of the foam, the epoxy adhesive, and the optional injected sealant bands at the joint face.

e. Depending on application and UL listing, can be supplied with a silicone coating on one side, both sides, or uncoated for use as a secondary seal.

f. Joint-Size Variation: Controlling uniform bellows appearance and the ability to handle variations in joint size through incremental sizing, are additional product features.

g. Movement Capability: Plus or minus 25 percent, 50 percent total or, plus or minus 50 percent, 100 percent total of nominal joint size, depending on the material selected.

h. Smoke Barrier: Innovative internal smoke barrier prevents toxic gases and fumes from penetrating the joint system.

4. Product Descriptions:a. Factory controlled, watertight, clean handling, UV stable, sound attenuating,

energy efficient and fire rated joint seal in a single, unified installation process.b. Designed to be used in horizontal expansion joints by itself, but it can be used
