{"product_id":"american-fyre-designs-mariposa-fireplace-hearth-16-rectangle-gfrc","title":"American Fyre Designs Mariposa Fireplace Hearth, 16\" Rectangle, GFRC","description":"\u003cp\u003eThe Mariposa 16\" Rectangle fireplace hearth from American Fyre Designs is built from Glass Fiber Reinforced Concrete — a material that earns its place in premium hearth design not through novelty but through genuine performance. GFRC delivers the substantial, stone-like presence of traditional masonry at a fraction of the weight, resisting the cracking, fading, and moisture damage that humbler materials tend to accumulate over time.\u003c\/p\u003e\u003cp\u003eAt 16 inches in a clean rectangle profile, this hearth is sized and shaped with intention. The Mariposa's geometry is uncluttered — no superfluous ornamentation competing for attention, just honest proportions that let the fire (and the room around it) do the talking.\u003c\/p\u003e\u003cp\u003eCompatibility is built into the design from the start. The Mariposa hearth is engineered for use with R.H. Peterson vented and unvented gas appliance burner systems, which means the fit between hearth and burner is a considered pairing rather than an afterthought. If you're specifying a complete fireplace installation, that alignment matters — and here it's already accounted for.\u003c\/p\u003e\u003cp\u003eGFRC's composition gives it an additional edge in outdoor and semi-exposed applications: it handles thermal cycling, humidity, and the occasional errant rainstorm with the kind of composure you'd expect from a material that has nothing left to prove. The finish holds, the structure remains stable, and maintenance demands stay refreshingly low.\u003c\/p\u003e\u003cp\u003eAmerican Fyre Designs has built a reputation on bringing architectural-grade concrete work into the hearth category, and the Mariposa hearth reflects that lineage. This isn't a decorative accent that merely suggests quality — it's a functional component that delivers it, installation after installation.\u003c\/p\u003e\u003cp\u003eFor exact finish options, burner configuration details, or installation requirements, please consult the product documentation or contact our team directly.
