Effective insulation is essential in wine storage cellars, and spray foam is the absolute best choice. These insulation installation contractors are familiar with California’s climate and the challenges presented by high temperatures. You can trust them to recommend materials that’ll insulate - not insult!

California dreaming?

The state’s typically warm weather conditions and dry air can leave you dreaming of unspoiled wine - unless your storage areas are appropriately insulated. For this, USA Spray Me urges you to invest in materials that’ll regulate your cellar’s temperature.

Hint hint - spray foam insulation. This is decidedly more advantageous than either fiberglass or rigid foam boards. Ideally, you’ll want to preserve cellar temperatures between 55 and 58 degrees: and spray foam is perfect for that. 

The result?

This will prevent you from needing to run ongoing cooling - offering cost-effective benefits alongside its positive impact on wine. Let USA Spray Me explain…

“Spray foam insulation offers superior air sealing,” states the document. “It expands to fill all gaps and cracks, providing excellent temperature and humidity control and acting as a moisture barrier to prevent mold and mildew. Despite its high cost and the necessity for professional installation, its performance in air sealing and moisture resistance makes it the top choice for wine cellar insulation.”

Vintage insulation

Spray foam, otherwise known as polyurethane foam insulation, is much longer-lasting than alternative materials. When you opt for spray foam, you’re choosing an insulation type that continues to provide benefits for a longer period.

Let’s recap those benefits:

  • Airtight seal creation for temperature regulation
  • Moisture barrier against mold and humidity
  • Better energy efficiency, leading to lower cooling costs 
  • Superior longevity for all the above


What’s more, maintenance and regular inspections can ensure that your spray foam holds up without the frequent need for reapplication. In winery settings, you’ll need to monitor the humidity levels in your cellars. Hygrometers can help you there, accurately measuring such data with ease.

That said, proper insulation upkeep typically calls for specialized help. Know any professional insulation experts? Why, of course you do - USA Spray Me!
