Cellar Construction
 
This is only a guide and shall be considered as minimum requirements. 
 
All interior walls and floors shall have a vapor barrier and a minimum of R13 
insulation. All exterior walls and ceiling shall have a vapor barrier and a minimum 
of R19 insulation. The vapor barrier shall be installed on the warm side of the 
insulation. All joints, door frames, electrical outlets or switches and any pipes or 
vents that go through the cellar shall be sealed to prevent air and moisture 
leakage into the cellar. Concrete, rock, and brick are not insulation or vapor 
barriers. 
 
Doors shall be of a minimum size, insulated to at least R13 and tightly sealed 
with high quality weather stripping. Be sure to seal the bottom of the door and fill 
gap between the door’s frame and wall before installing the cap molding. 
In order to maintain 55 °F in the wine cellar, the ambient temperature 
surrounding the enclosure shall not exceed the temperature of the cellar by more 
than 25 °F. No cellar wall shall receive direct sun or strong wind. 
 
Lighting shall be of low wattage, with a timer to insure lights are not left on when 
the cellar is not occupied. 
 
The cooling system will not be able to maintain the proper temperature if fresh 
moisture-laden air is constantly being introduced to the cellar. Symptoms of this 
condition are; cooling unit runs all the time with only a slight reduction in 
temperature and/or water overflows from the unit. Because of the temperature 
difference between the inside and outside, very small cracks can allow large 
amounts of outside air to enter into the cellar. Please be aware that moisture can 
pass through solid concrete, paint and wood. Often a newly constructed cellar 
contains fresh wood, paint, concrete and other building materials. These 
materials contain large amounts of moisture. When placed into operation in this 
type of environment, the system will work harder to remove this extra moisture 
resulting in increased “run” time.
