Details
ULTRA BLOCK is a pre-engineered, patented textile fiberglass with fiberglass matt facing, containing approximately 30% by weight unexpanded vermiculite. ULTRA BLOCK is primarily used in fire rated construction joints.
To be an effective fire blocking joint packing system, a product must remain highly resilient and must completely fill the moving joint for a great number of years. In most packed and caulked joints, examination of the resiliency of the forming material is difficult to check, as the material is covered up with sealant. Many joint packing materials, such as mineral wool and ceramic fiber, are not designed to handle joint movement and may fall out or slump in the joint when subjected to continuous joint expansion and contraction. Under fire situations, the fire blocking material must be in the same condition as when it was installed, meaning that the material must completely fill the void in order to block a fire. ULTRA BLOCK has a unique patented, hinged design and composition that remains highly resilient under the most extreme conditions.
Applications
ULTRA BLOCK, when used together with an approved sealant, provides a 2-Hour, 3-Hour, or 4-Hour fire rated joint system as designated by design configuration, which is capable of withstanding ± 50% expansion and contraction. Most sealant manufacturers in the United States have tested one or more of their sealants in a UL classified ULTRA BLOCK system ranging in joint size from 1/2” up to 7”. We ask that you verify your sealant selection complies with our UL system design. Approved sealant manufacturers include:
