What are the downsides of a double-sided fireplace design?
The main downsides: you lose a wall for a TV or art, since both faces are glass; you style and clean two sides instead of one; framing and venting cost more; and heat splits across two rooms so neither gets as warm. They are also best planned during construction — retrofitting one into a finished wall is a bigger job.
No back wall to use
This is the one people don't see coming. A true see-through fills the whole opening with glass on both faces, so there's nowhere to hang a TV, mount art, or run built-ins across the fireplace. If a media wall is on your wish list, a double-sided unit and a mounted TV are mutually exclusive — a single-sided fireplace is simply the better tool for that job. Worth deciding up front, because it drives the whole room's layout.
Heat and glass tradeoffs
The output divides between two rooms, so a see-through is wonderful as ambiance but weaker as a primary heater than the same unit facing one direction. More glass surface also means more hot glass — the outer faces of a running gas fireplace get hot, so a barrier screen matters with kids and pets. And there's twice the glass to keep clean and twice the interior to style so it looks good from both sides, lit or dark.
Cost, framing, and timing
Deeper framing, a longer vent run, and two finished faces all add cost, and it's genuinely hard to retrofit one into a finished wall — these belong in a new build or a remodel that's open to the studs. None of that means don't do it; a see-through can be the best decision in the house.
