Our fire barrier fits joint openings 1" and up.
Our fire and vapor barrier systems are designed to be used with most of our expansion joint cover assemblies. Each model is fire rated for either two or three hours, and allow for lateral shear, which is feature unique to the industry. All fire barrier systems are third-party tested for optimal performance.

We've Got it Covered
When it comes to expansion joint cover selection, you're not alone. We've got you covered with guides on sizing, waterproofing, fire barriers, building movement, and more.
Joint Sizing--Simplified
A critical element of proper joint sizing is to keep proper movement types and ranges in mind.
Types of Building Movement
Prior to selecting a cover, it is crucial to consider which type(s) of building movement your project might encounter.
Building Types: Environments To Consider
Understanding Fire-Rated Expansion Joints
Fire-rated expansion joints are necessary to maintain building safety. Here’s how to incorporate them.
Waterproofing an Expansion Joint
There are several aspects to consider that help prevent water from leaking through the expansion joint and into your building.
Questions to Ask Before Selection
Consider these topics on movement, safety, aesthetic, building resilience, and more when choosing the best cover for your building.
HOW TO PREPARE FOR A FIRE BARRIER INSTALLATION
General Considerations: What fire rating are you trying for?
• Be sure to select the appropriately UL listed product for the application
• Check that your job site conditions are the same as the UL Listing
Floor Installation Prep: Are your concrete surfaces properly prepared?
• Surface mounted covers require a square, clean joint
• Blockouts must be level for recessed covers
• Set the substrate at the correct elevation prior to the fire barrier installation
Wall Installation Prep: Are your substrates finished correctly?
• Drywall must be installed on the inside of the joint
• Joint edges must be parallel to one another
• Be sure the proper blocking connection points are made, if applicable
(Typically needed in 2 hour rating situations)
• Be mindful of floor fire barriers above and below for proper transitioning
Performing an expansion joint cover transition from floor to wall is not an easy task, but with the help of our video and some practice, you will be able to master the RFX 4" floor-to-wall transition.
