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?
Yes. Every shelf is certified non-combustible and safe for direct fireplace mounting. Meets all US building codes for fireplace clearance.
What is the starting price?
Pricing starts at $495. Final price depends on length, depth, finish, and any add-ons (LED lights, brackets, banding) selected in the configurator.
How long does Floating Fireplace Mantel Shelf take to ship?
Custom-built and shipped in 14–21 days. Free shipping included on every order to the contiguous US.
Where is Floating Fireplace Mantel Shelf made?
Hand-finished in Milwaukee, Wisconsin across 25+ heritage finishes. Every shelf is reviewed before it ships.
What is the warranty?
ExceptionalFire warranty: 3 years workmanship · 2 years finish. Covers qualifying manufacturing defects for the original residential purchaser from delivery. Longer applicable manufacturer coverage also applies.
