Product Information

Back to Top

One of the biggest obstacles with traditional fire barriers is that they can never get wet. Many times, fire blankets will remain uncovered while installed in the joint.With that type of exposure the barrier will have to be replaced because once the barrier is wet, it is destroyed...unless you’re using Water Guard™. This system gives you peace of mind so you don't have to worry if the fire barrier is installed for a few days, weeks or months before the expansion joint covers are installed. 

Fireline 520™ Water Guard™ Series systems are the only fire blankets with a US patented, UL 2079 rated water proof design. The Water Guard™ protects the integrity and performance of the fire barrier from extended exposure to the elements.
