Willseal FR-V is designed to be used in vertical wall installations 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-V is a second generation, unified fire rated, sound, energy, and waterproof sealant system that can be supplied for +/- 25% and +/- 50% joints. Willseal FR-V is not made of thin, unbonded vertical layers that can delaminate with joint shear or thermal shock. In addition to UL 2079, Willseal FR-V 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.
Can be supplied uncoated, coated on one side, or coated on both sides, depending on UL listing. Refer to www.ul.com.
