19 Nov Options in Wine Cellar Insulation

If you want to preserve wine properly and create a custom wine cellar, you must first learn more about wine cellar insulation. Even the finest cooling systems will fail to maintain the precise temperature and humidity required for wine storage without proper insulation.

Building a wine cellar is a time-consuming task with several things to consider. Hiring an experienced professional can help ensure you have a safe and ideal environment for wine storage. However, it’s essential to take the time to study what you’re doing so every aspect of the building process runs correctly.

About Wine Cellar Insulation Materials

Since insulation is so crucial to storing wines correctly, here we will look at three wine cellar insulation materials to consider:

1. Fiberglass Batt Insulation: An Excellent Choice

Wine storage experts suggest that you need to use at least R-13 insulation, which you can achieve using fiberglass batts. If you opt for this insulation, you will need to keep 6-millimetre vapour barriers on the warm sides of all walls to prevent interstitial condensation. Take your time installing this since improperly installed vapour barriers may trap moisture inside the walls.

Some professionals cover the whole interior of the walls, leaving the plastic vapour sheeting free in the stud cavity. Professionals install insulation batts between each stud using this approach. Another possibility is to roll the batting in between the stud slots. Once complete, the vapour barrier sheets encase the entire cellar. Remember that if you want a genuinely effective vapour barrier, every single wall, as well as the floor and ceiling, need a plastic sheeting cover.

This is the cheapest technique of insulating your wine cellar, but it also presents the most significant problems if the installation is incorrect. Even a minor gap can lower the insulating effectiveness of your wine cellar by up to 25%. If you select this technique, make sure the custom cellar builder you hire is knowledgeable enough to handle this job.

2. Rigid Foam Boards – A Better Alternative

Rigid foam board composed of polystyrene is a traditional wine cellar insulation material. This form of insulation will need plastic vapour barriers. When using rigid foam boards for wine cellar insulation, you’ll need two layers, each an inch and a half thick, to give your wine storage an R-19 insulation rating.

These are simple to install, making them a popular option for wine cellars. However, they have the drawback of being tough to manoeuvre around wiring, plumbing, or conduits. If any of these must pass through your basement wall, you will have to wrap the lines and pipes in foam or drill holes in the board for the wiring and then fill up the gaps with spray foam insulation.

This relatively affordable alternative helps maintain a compromise between the low cost but increased danger of fibreglass batt insulation and the pricier polyurethane spray foam solution. It’s also less difficult to install correctly than fibreglass batt, although not as straightforward as polyurethane spray foam: particularly if you have many cracks, conduits and holes to fill in.

3. Spray Foam Insulation Is The Most Effective Option

Nothing surpasses closed-cell spray foam for wine cellar insulation. You can achieve R-19 insulation using only three inches of this effective polyurethane spray foam. Even better, spray foam skims over the surface producing its vapour barrier, and you will not require any plastic sheeting. It is critical to use closed-cell foam rather than open-cell foam in this application. Closed-cell spray foam hardens much more firmly and effectively prevents convection both within and through the walls cavities.

The fact that polyurethane spray foam expands is one of its many advantages. Once sprayed, it will travel in to fill up every crater, hole, and aperture, even those surrounding wiring and pipes. There are no holes when you use this product, so there is no way for vapour to seep through the material and create a moisture problem. This is a standard method of insulating custom wine storage cellars that have excessive pipe and wiring installations.
