FIRE PROOF
Thermastone is fireproof and heat resistant. It can withstand extreme temperatures without discoloring or deformation.
AMAZING REALISM
Thermastone cures a stone like hardness which allows for fine details in molding and sculpting. Natural elements look and feel real to the touch.
LIGHTWEIGHT
Thermastone Mantels are light in weight. In fact, our heaviest 7ft Modern Beam weighs just 36-3/4lbs, making one-person installation a breeze.
LOW MAINTENANCE
Caring for a Thermastone surface is much simpler than cleaning and protecting a natural wood or stone product.
NON CHALKING
Thermastone surpasses all other ® fire-retardant materials such as MGO and Poly-resin as they disintegrate over time under the harsh outdoor environments of UV radiation and high temperatures of an open flame.
PROCOAT HEAVY-DUTY PROTECTION FROM THE ELEMENTS
Our trademarked coating system is a proprietary process co-developed with a industrial coating supplier. The coating is specially formulated to create an extremely strong bond with the specially prepared magnesium oxide.

How to Measure

Always measure to the nearest 1/8 inch. Take each dimension twice and use the smaller number — fireplaces aren't always square.

Frequently asked questions
How far does a mantel need to be from the firebox?
The 2021 International Residential Code (IRC R1001.11) requires combustible materials (wood mantels, trim) to be at least 6" from the firebox opening. Add 1" of clearance for every ⅛" the material protrudes from the wall. Non-combustible mantels (concrete, steel, properly-rated mineral cores) can be installed closer or even at zero clearance — check the firebox manufacturer's listing and your local code.
What's the difference between combustible and non-combustible mantels?
Combustible mantels are made of wood or wood-composite materials and must follow strict clearance codes (typically 6"+ from firebox). Non-combustible mantels are concrete, steel, glass, or composite materials with mineral cores — they don't burn or off-gas under heat, so codes allow much tighter installation, often right next to the firebox. For zero-clearance / direct-vent gas fireplaces, non-combustible is usually the only code-compliant option.
How do I install a floating mantel?
Most floating mantels mount via a hidden steel cleat or rod system attached to wall studs (or masonry anchors for stone/brick walls). The mantel slides over the bracket and locks. Installation typically takes 30–60 minutes with basic tools (level, drill, stud finder). Concrete and steel mantels are heavier — verify your wall can support the load (typically 50–120 lb depending on length).
Will the mantel arrive ready to install?
Yes. EF mantels ship fully finished with the mounting hardware included. Standard sizes ship in 5–10 business days; custom sizes are made-to-order in 2–4 weeks. White-glove freight delivery is included on every order.
What's the warranty and return policy?
EF mantels carry a 5-year warranty against manufacturing defects. Quick-Ship / standard-size mantels have a 30-day return window on unused units. Custom-size mantels are non-returnable. Damage in transit is fully covered — file a claim within 48 hours.
