How do I Frame Out my Wine Cellar?
- 2″X4″ wood studs are generally used for the walls, but 2″x6″ studs can be used for thicker insulation
- Ceilings can be framed with furring strips against floor or roof joists
- The vapor barrier must be installed (carefully) first and be looped up into the joist space to form a complete seal
- The insulation should then be pushed up into the joist space and held in place by the furring strips or other framing
- If the walls are against an outside foundation wall, there should be a minimum 1-inch gap between the walls for air circulation purposes
- It’s easier if the vapor barrier is installed on the wall, as it is framed on the floor before it is tipped up into place
Why is a Vapor Barrier Important?
Vapor Barrier: An enclosure around an entire room which is needed to control humidity.
When using conventional insulation, a minimum of 4 mil. plastic is recommended with seams overlapped and taped. The vapor barrier must be installed on the outside (or warm side) of the cellar insulation. This is to prevent condensation from forming on the vapor barrier and potentially wetting the insulation and forming mold.
Closed-cell foam does not require additional 4 mil. plastic and acts as both cellar insulation and a vapor barrier.
What is the best way to insulate my wine cellar?
- 3½ inches (9 cm) in walls
- 6 inches (15 cm) in ceiling
Putting 6 inch (15 cm) insulation all around is a better option
Insulate the Floor?!
If there is space below the floor, the floor should be insulated as well from below. If the floor is existing concrete, insulating it will be difficult. Therefore, its impact on the heat load should be considered when sizing the wine room cooling unit. If the floor does not have a vapor barrier beneath it, a waterproof sealer is recommended before any other flooring such as wood or carpet is installed.
