Modern Double Corner Three-Sided Gas Fireplaces

Modern Double Corner Fireplaces are three-sided gas fireplaces: a corner bay with flame visible across three faces at once, and they can reach from one side of an architectural element to another. The multiple viewing angles and glass-to-glass paneling allow a clear line-of-sight to the flame with unit lengths of 30″ to 100″. Modern Double Corner Fireplaces create the perfect setting for any home or business.

Modern Double Corner Fireplaces are certified and approved by CSA to be installed in North America, including California and Massachusetts.

What Makes a Three-Sided Fireplace Different

A three-sided fireplace — also called a bay fireplace — carries one continuous flame across three open glass faces, so the fire reads from the front and from both sides at once. Where a flat fireplace serves a single seating area, a three-sided gas fireplace anchors an open plan: visible from the kitchen, the dining area and the main seating zone at the same time. Flare builds the Double Corner in lengths from 30″ to 100″, in three glass heights, with black diamonds, glowing embers or driftwood logs.

An open corner with nothing running through it

This is the difference that never shows up in a specification table. Every multi-sided fireplace has to resolve the open corner where two glass faces meet, and that resolution is normally a metal post or bracket — a vertical line drawn straight through the middle of the flame. The Flare Double Corner is frameless: glass meets glass at the corner, with no visible metal frame, post or bracket interrupting the view. From across the room the fire reads as one continuous body of flame wrapping the bay, rather than three separate windows set into a surround.

Cool Touch Wall, on three exposed faces

With flame open on three sides, what happens to the heat around the fireplace matters more, not less. Flare’s Cool Touch Wall keeps the wall above the fireplace relatively cool, so a television or an art piece can be mounted closer to the glass than a traditional fireplace allows, when installed according to Flare’s installation manual, heat release requirements and project-specific specifications.

Bay or peninsula?

The Double Corner is a bay: it sits into the corner of a room with the flame wrapping three faces. If the fireplace instead needs to stand free and divide the room, that is the Room Definer, Flare’s three-sided peninsula. Both are three-sided; they differ in where they sit, not in how many faces of flame you get.

Three-Sided Fireplace FAQs

What do you call a three-sided fireplace?

A three-sided fireplace is usually called a bay fireplace when it sits into a corner with flame on three faces, and a peninsula fireplace when it stands free and projects into the room. Flare builds both: the Double Corner is the bay configuration, and the Room Definer is the peninsula. Some manufacturers also use the term pier for the freestanding version.

Does a three-sided fireplace have a metal frame at the open corner?

Not on a frameless unit. Multi-sided fireplaces normally resolve the open corner with a metal post or bracket where the two glass faces meet, which puts a vertical line through the flame. The Flare Double Corner is frameless: glass meets glass at the corner with no visible metal frame, post or bracket, so the flame reads as one continuous body of fire across all three faces. One exception: if the fireplace is ordered in the safety screen configuration, the screen frame does create a black line in the corner. This is why most corner units are sourced and specified as double glass.

What sizes do three-sided gas fireplaces come in?

Flare Double Corner three-sided fireplaces are available in lengths from 30 inches to 100 inches, in three glass heights: 16 inch regular, 24 inch high and 30 inch extra high. Dimension drawings, framing guides, CAD, SketchUp and Revit files are published for every model on this page.

Can the finish material above a three-sided fireplace rest on the glass?

No. The finish above the opening must be self-supporting and carried by the framing and the structure above. A frameless fireplace has no lintel above the glass to spread that load, and the glass is not a structural member. Specify a header or equivalent support in the framing, and confirm the detail against Flare’s installation manual and the framing drawings for your model.
