Fire Rated Roof Expansion Joint

For 70 years wba has proudly led the industry in the manufacture and design of expansion joint systems to meet the unique demands of projects across the globe.

Fire rated roof expansion joint. Building expansion joint slab and wall openings inherently create a pathway for fire and smoke to travel through. When these joints occur in a fire rated floor or wall a product or system must be used that has been rated. We ve designed our systems to fit any project s needs and provide superior protection to keep the threat contained. Fire rated willseal fr h 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.

The main difference between fire barriers and fire stops is the allowance for movement. Our industry leading fireline 520 expansion joint fire barrier products provide protection for 2 3 and 4 hour rated conditions. We are your strongest partner for expansion joint systems and responsible solutions. Us patents covering emseal s fire rated expansion joint product portfolio include.

Gaf everguard everguard extreme expansion joints are made of 60 mil thick reinforced tpo membrane and come in five standard sizes and two convenient styles to accommodate both roof to roof and roof to wall applications. A partition wall or ceiling traverses a construction joint expansion seismic or building control element in the base building structure. Where an interior wall or partition runs in an uninterrupted straight plane exceeding 30 ft 9 m in length or height. To maintain the integrity of the interrupted fire rated assembly and prevent the spread of fire a fire barrier or fire stop should be used.

An expansion joint that runs through a building may interrupt a fire rated assembly. These joints are necessary to accommodate expected building movements due to thermal changes wind sway and differential movement typically caused by seismic events.

The dih series is designed for expansion joint openings with the ability to provide a smooth and virtually impact free transition between opposing floor surfaces in addition to accommodating heavy rolling loads and multi directional seismic movement. In most commercial buildings expansion joints are a fact of life. We strive to provide solutions that will best fit your needs and relieve the stresses of your project.
