Fireproof non combustible fireplace mantels and solid oak heat shield deflector beams. These unique mantel shelves enable placement closer to the heat source than standard timber shelves, allowing for adherence to current UK building regulations. Very popular for those who wish to place a TV above their stove. Below are my most popular sizes, but feel free to reach out if you need custom thicknesses or depths. safety distances to heat source vary from non combustible and shielded oak so please read descriptions for info.. :)
