Fire-rated expansion joints

MetaFlex Pro barrier series spans the 2 Hr and 3 Hr, plus Shear and Undermount versions, each designed with the installer in mind. Measured to UL 2079 standards, they meet International Building Code requirements and related tests for fire resistance and protection. Available for floor expansion joints up to 18-in. maximum open conditions, they cover nearly every commercial building application.

The Metaflex Pro 2-Hr and 3-Hr both offer a single package installation with factory fit flanges affording easy, drop-in placement. Company has eliminated the need for fire caulking along the sides of the joint and simplified splicing. Metaflex Pro Shear shares the same features and performance of Metaflex Pro 2 Hr and 3 Hr, while also allowing for up to 100 percent shear movement—critical to buildings prone to high seismic activity. Metaflex Pro Undermount offers a two-hour rating from the bottom of the slab, especially suiting retrofit conditions, applications with penetrations running through the joint, or other situations that would prevent installation from above.

Additionally, MetaFlex Pro series joints double as a smoke barrier, pass air leakage testing per UL 2079; and, contribute to LEED credits under the categories of recycled content for steel and ceramic blanket plus regional material. Balco USA, 800/767-0082; www.balcousa.com
