Product Features
2 or 3 hr horizontal fire rating in accordance with UL 2079
Movement: 50% (± 25%) or 100% (± 50%) of nominal joint size, depending on the material selected
Supplied with a silicone coating on one side, both sides, or uncoated for use as a secondary seal
Willseal FR-H provides a factory controlled, watertight, clean handling, UV Stable, sound attenuating, energy efficient and fire rated joint seal in a single, unified installation process.

Description
Willseal FR-H is designed to be used in horizontal expansion joints by itself, but it can be used behind any other expansion joint cover, plate or filler where joint depth allows. Because it is coated on both sides, it can be placed with either side exposed, adding to the versatility and increasing the aesthetic fireproof sealing options. Willseal FR-H is a second generation, unified fire rated, sound, energy, and waterproof sealant system. Willseal FR-H is not made of thin, unbonded vertical layers that can delaminate with joint shear or thermal shock. In addition to UL 2079, Willseal FR-H has been independent lab tested to ASTM 330, 331, 283 & 547 for water and air penetration. It has been tested and passes TAS 202/203 requirements for hurricane force exposure.

Material
Willseal FR-H features a waterproof silicone face on each side of a fire-retardant impregnated foam sealant without the need for additional intumescent bellows. Willseal FR-H does not rely on the silicone face or intumescent bellows to provide its fire rating. This is an important safety improvement over first generation materials that are subject to vandalism or damage to the thin silicone/intumescent bellows. The main function of the silicone face is to enhance the waterproofing nature of the sealant and provide a durable traffic rated seal. Willseal FR-H Type UC is supplied without silicone for use as a secondary seal.
