Can a see-through fireplace be installed in an exterior wall so it's indoor/outdoor?
Not with a standard indoor see-through unit — a fireplace opening onto outside air needs an outdoor-rated appliance with weather, drainage, and clearance provisions an interior box doesn't have. The good news: there are purpose-built indoor/outdoor see-through fireplaces made for exactly this, and they do it right. We'd spec one of those rather than try to adapt an indoor unit, which would void its warranty and fail.
Why an indoor see-through won't work through an exterior wall
An indoor double-sided fireplace assumes both faces live in conditioned space. Point one face outside and you've exposed a unit that was never built for wind, rain, freeze-thaw, or the temperature swing across the wall — the electronics, the finish, and the venting aren't rated for it. It also creates a hole in your building envelope that has to be sealed and flashed like the weather boundary it now is. Forcing an interior model into that role voids the warranty and sets you up for corrosion and failure. It's not a shortcut we'll take.
The purpose-built indoor/outdoor option
What you actually want exists as its own product: an indoor/outdoor see-through fireplace engineered with one weather-sealed face and provisions for drainage, the temperature differential, and outdoor exposure. Built for the job, it gives you fire from the living room and the patio through a single unit — exactly the effect people picture. We'd help you choose from the outdoor-rated lines we carry and size it to the opening. It's a premium build, but it's the honest way to get the indoor/outdoor fireplace you're after.
Made for our mountain patios
This is a natural fit for WNC, where cool evenings run most of the year and a covered patio or porch off the great room earns its keep well into the shoulder seasons. Weather sealing matters more here than most places — our freeze-thaw cycles and mountain weather punish anything that isn't rated for it. On the Asheville and Hendersonville mains we tie into natural gas; out in the cabins it's propane, which needs the right orifices. Connecting either is licensed work we permit and pressure-test.
