Climate‑controlled wine cellars
Holding a cellar at fifty-five degrees and sixty percent humidity inside a Las Vegas house whose exterior sees a hundred and ten puts more load on the envelope than almost anything else you will build. The failures are slow and hidden, which is why the detailing matters.
Building science, in millwork.
The envelope
Vapor drive across a cellar wall in a Las Vegas July runs hard and in one direction. You need a continuous vapor barrier on the warm side, insulation sized for that difference rather than to code minimum, and penetrations that are actually sealed.
A barrier interrupted by one carelessly cut light box has stopped being a barrier. Get it wrong and you do not feel it: you get condensation inside the wall, and the damage is done well before anyone opens it up.
Sizing the cooling
NeXGen sizes cellar cooling from the actual heat load: envelope, glazing, lighting, door, how often you open it, how much thermal mass sits inside.
Undersized equipment runs constantly and still misses. Oversized equipment short-cycles and pulls the humidity down, which dries corks, the failure the room exists to prevent. Condensate needs somewhere to go, and the unit needs service access that does not involve dismantling your racking.
Glass and doors
Glass walls are why many cellars get built and the hardest part to detail: insulated glazing, a gasketed door with a real seal, and a frame that does not turn into a thermal bridge.
Treat the cellar door as an exterior door. Specified as interior joinery, it sweats.
Racking
Racking is carpentry, in species that tolerate sustained humidity, detailed for what you actually store. Large formats, magnums and case storage each want different bays.
Below grade in the southern Las Vegas valley, add excavation through caliche. NeXGen quotes that from the start.
- Envelope
- Continuous warm-side vapor barrier, sealed penetrations
- Cooling
- Sized from a heat-load calculation
- Glazing
- Insulated glass, gasketed door, no thermal bridge at the frame
- Racking
- Humidity-stable species, bays detailed for large formats

What owners ask
about the cellar.
Can a cellar go anywhere in the house?
Almost anywhere, and where it goes changes the envelope. Holding a cellar at fifty-five degrees and sixty percent humidity inside a Las Vegas house whose exterior sees a hundred and ten puts more load on the assembly than almost anything else you will build, so a room against an exterior wall and a room below grade are different problems.
What actually fails in a cellar?
The envelope, quietly. Vapor drive across a cellar wall in a Las Vegas July runs hard and in one direction, so a barrier interrupted by one carelessly cut light box has stopped being a barrier. What you get is condensation inside the wall rather than a symptom you can see.
Why not fit a larger cooling unit and be safe?
Because oversized equipment short-cycles and pulls the humidity down, which dries corks, the failure the room exists to prevent. Undersized equipment runs constantly and still misses. NeXGen sizes it from the actual heat load: envelope, glazing, lighting, door, how often you open it, and how much thermal mass sits inside.
Does a glass-walled cellar work in this climate?
Yes, detailed properly. Insulated glazing, a gasketed door with a real seal, and a frame that does not become a thermal bridge. Treat the cellar door as an exterior door. Specified as interior joinery, it sweats.
