Hewn Mortise Beam

The Ambiance® Hewn Mortise Beam mantels show an extraordinary realistic wood look while being resistant to heat.  They are suitable for outdoor applications. Ideally, protected from the elements as part of an integrated fireplace/pergola combination.  Unprotected, the surface will accumulate white salt leaching that needs to be removed with a 50/50 solution of water and vinegar.  The surface would also need to have a protective sealer applied at least twice per year to protect against the freeze-thaw cycles in colder climates.  Available in 5′ or 6′ size and in three colors to fit your fireplace and decor.  They are molded directly from antique timbers salvaged from historic barns, farms, homes, and cabins across the Kentucky Bluegrass region. Crafted with a patented non-combustible Burncrete casting to authentically replicate the rich wood grain and character details of antique wood.  The result is a unique non-combustible peace of art!
