Proper insulation is one of the factors that contribute to the effectiveness and efficiency of a wine cellar in protecting and preserving your valuable wines.
Unstable wine storage conditions and inadequate insulation will cause your wines to rapidly deteriorate. Building a wine cellar or modern wine closet must include proper insulation. Wine cellar insulation, just like wine cellar cooling systems, plays a crucial role in preserving the taste, aroma, and overall quality of wine before they are suitable for consumption.
Not only will you learn the best insulation for a wine cellar in this guide, but you'll also know the importance of insulation for wine cellar temperature and wine storage humidity control.
Before we get started, let's tackle some of the commonly asked questions about wine cellar insulation.
The “R" in R-value stands for resistance. It is the measurement of the insulation’s ability to resist heat flow. In general, a higher R-value performs better and has a greater insulation performance by slowing down the heat transfer. However, that depends on what state you live in and the composition of the materials.
R-13 — This insulation is often used alone or in conjunction with other insulating materials in floors and walls (intended to be used in a 2x4 wall). For wine cellars, insulation must have a minimum R-13 value.
R-19 — Usually recommended for walls (made to fit in a 2x6 wall) and the minimum requirement for ceilings.
R-30 — Now this is the best insulation value for ceilings. This is also perfect for above-ground floors.
Note: Insulation requirements and efficacy may vary depending on the material and climate.
Even though concrete is one of the best materials for a wine cellar, it still needs to be sealed because it can be unexpectedly porous. Concrete walls and floors don't provide enough R-values, so additional insulation is needed.
The key to keeping a consistent wine cellar cooling and humidity is Proper Insulation. Wine cellars should be kept dry and airtight to keep them at the right temperature and protect the bottles from damage. Check this Step-by-Step Guide to learn more about how to build a wine cellar!
Make sure to also invest in high-end and reliable Wine Cellar Cooling Units.
While there are many options for insulation, we recommend 3 of the best types to ensure that your wine cellar is properly insulated: Fiberglass Batt, Rigid Foam, and Polyurethane Spray Foam.
Let’s go over the three most popular methods and the best insulation for wine cellars.
According to wine storage specialists, R-13 is the minimum recommended value of insulation for wine cellars. Fiberglass batts are a good option for delivering this value. If you choose this material for your wine room, be sure to cover the warm side of the walls with a 6 mil plastic vapor barrier.
Fiberglass batts are the most affordable insulation material for wine cellars. They are often installed poorly, which then loses 25% of their effectiveness if there are even tiny gaps. To ensure that your fiberglass batts are installed properly, we advise getting a qualified wine cellar builder or contractor to do it.
To create a vapor barrier, you may cover the entire wine room's walls, ceiling, and floor with plastic sheets. To install the fiberglass insulation between each stud, you may wrap the entire interior of the walls while leaving the plastic sheeting loose in the stud cavity. Once the batting has been installed between the stud cavities, plastic sheeting is covered the entire wine cellar structure.
Note: Building a wine cellar often includes the use of plastic sheeting, which works well as a vapor barrier. Use this method if you're insulating a wine cellar with fiberglass batts. A plastic vapor barrier can also be used for rigid foam board insulation, which is what we'll talk about next...
Another type of material used for insulating wine cellars is Polystyrene, commonly known as Rigid Foam. Applying a plastic vapor barrier is also necessary if you're going to insulate your wine storage with rigid foam boards. Two layers of rigid foam boards that are at least 1.5 inches thick will give your wine cellar R-19 insulation.
In addition to being cost-effective, rigid foam board insulations are a better choice because they are easy to install. However, the rigid foam must be used to wrap all pipes and wires if any piping, conduit, or wiring needs to pass through the wine cellar wall. After that, spray foam is applied to fill in the gaps.
Note: If you plan to use rigid foam board insulation, make sure to apply a plastic vapor barrier to your wine cellar’s walls, ceiling, and floor.
Polyurethane closed-cell spray foam is the best and most reliable type of insulation for wine cellars.
This material provides R-19 insulation with a 3-inch application. Spray foam stretches and expands, filling all the gaps and cracks, and leaving no spaces. No need to install plastic sheeting since the polyurethane forms a vapor barrier as it glides over. Additionally, spray foam makes a tight seal around any piping, conduit, or wiring that passes through the wall, ensuring that vapor cannot possibly penetrate through.
We recommend the polyurethane closed-cell spray foam because of its many benefits, such as:
Regardless of how well the space is sealed and insulated, you’ll need top-performing Wine Cooler Units.
Both proper insulation and wine room cooling units are the keys to how to store wine properly. A cold, dry, storage condition and consistent temperature are vital, thus you'll need one of these wine room coolers to keep the temperature steady even on hot, summer days.
