Horizon Non-Combustible Mantel

from $959.00

Add sleek, modern elegance to your fireplace with the Horizon non‑combustible floating mantel. Inspired by mid-century modern design, this slim-profile concrete mantel delivers style, safety, and simplicity for contemporary fireplace makeovers.

Like the beautiful mid-century designs of Frank Lloyd Wright, our Horizon mantel adds crisp, contemporary flair to a linear fireplace installation.  The Horizon’s concrete construction and coloring give a modern touch to a room and emphasize the linear look.  Sleek, slim lines of a floating mantel and hearth anchor the fireplace, creating a lovely symmetry.

This concrete beam mantel is a great start to a fireplace makeover where you're looking for a contemporary fireplace mantel. We have seen an increasing use of the Horizon fire safe mantel in floating mantel and floating hearth combinations used in today’s linear fireplaces. The Horizon noncombustible mantel is becoming a favorite of builders and designers going for an industrial loft look.

Our hollow core designs make these mantels much lighter than a solid concrete beam and much easier to install over existing walls. Extremely easy to install and DIY friendly, the Horizon modern beam mantel is perfect for a fireplace makeover

Available in 2 standard colors and two standard lengths, the Horizon modern beam mantel is fully customizable to give you more design options. Contact the store for customization details.
