Placement & Clearance
For safe installation, we recommend positioning your non-combustible mantel shelf at least 15 cm away from the heat source. This minimum clearance allows for adequate airflow and heat dispersion, helping maintain safe operating temperatures around your wood burner, log burner, inset stove, or open fireplace.

Because our mantel shelves are made from a non-combustible reinforced composite material, they are highly resistant to heat and will remain stable even when installed closer to the heat source than traditional timber mantel beams.

Under UK Building Regulations – Approved Document J (Combustion Appliances and Fuel Storage Systems), combustible materials such as timber mantel beams must usually be installed at significantly greater distances from a stove or fireplace opening. Non-combustible materials, however, are not subject to the same clearance restrictions, which makes them an ideal choice for fireplace mantel shelves above wood burners and stoves where space may be limited.

Even when using A1 non-combustible materials, we still recommend allowing a minimum 15 cm clearance to promote airflow and prevent excessive heat build-up. Always follow your stove manufacturer’s installation guidance and consult a qualified installer or building professional where required.

This makes our fireproof mantel beam shelves a practical and safe solution for installation above log burners, inset stoves, open fires, and kitchen chimney hoods, combining modern fireplace safety with durable, heat-resistant design.
