Omega Block

Product Description
Omega Block products are composed of non-toxic incombustible materials whose air permeability and relative fire-resistance characteristics are unequaled.  Fully approved for constructing ventilation devices by MSHA, Omega Blocks reduce labor because they cover the area of 3 normal concrete blocks.  Omega Blocks are easy to use because they can be accurately cut to size with a handsaw.  A typical brattice stopping is dry stacked using alternating courses and then sealed with an approved sealant about the roof, rib and seams.
