Frequently Asked
Why does non-combustible matter?
Traditional wood mantels require a minimum 12" clearance from the fireplace opening, which forces a higher mantel position and adds a fire-hazard risk over time as wood warps and discolors. Non-combustible steel can be mounted directly above the firebox with zero clearance, meets all building codes, and is safe above both gas and wood fireplaces — giving you a cleaner look and a lower profile.
Is Floating Fireplace Mantel Shelf - Non-Combustible Metal Mantel, Any Size, Modern Fire Rated Steel Shelf, Black non-combustible?
Yes. Every shelf is certified non-combustible and safe for direct fireplace mounting. Meets all US building codes for fireplace clearance.
