What Is Climate-Controlled Storage?

1. Wood Furniture and Antiques

Storing wood furniture and antiques properly means using climate-controlled storage to avoid damage. These items are highly sensitive to changes in their surroundings, which can weaken their structure over time.

"Antiques incur the worst problems when humidity suddenly shifts from extreme lows to extreme highs. Allowing for gradual fluctuation can make a world of difference".

To keep these items safe, focus on controlling three key factors:

Storage Factor	Ideal Condition
Temperature	68–75°F
Humidity	35–65%
UV Exposure	Minimal

Wood naturally reacts to its environment, making stable conditions essential. If humidity gets too high, mold can form, and the wood may swell. On the other hand, low humidity dries out the wood, weakening joints. Temperature swings can also harm the wood and adhesives.

"The constant cycle of expansion and contraction over time is what causes the wood to warp and crack. If you keep your furniture in a temperature-controlled environment all year long, you shouldn't have a problem!".

To protect your wooden items in storage, follow these tips:

• Use a wood-safe cleaner to clean the items before storing.
• Place them on wood pallets to keep them off the ground.
• Cover with breathable cotton to shield from dust while allowing airflow.
• Keep them away from vents to avoid direct air exposure.
• Use a hygrometer to regularly check humidity levels.

These steps will help ensure your wood furniture and antiques stay in great condition, ready to enjoy for years to come. Next, we’ll explore how to care for other delicate materials.

Sticking to these conditions helps protect your collection from unnecessary damage.

How Temperature Affects Wine

Storing wine at room temperature can speed up aging by as much as four times. In fact, every 18°F (10°C) increase doubles the rate of chemical reactions in wine.

"A warm environment can actually 'cook' or oxidize, leaving the wine tasting burnt and flat. Too cold an environment, and the chemical reactions that foster aging slow down. Dramatic fluctuations in temperature can also cause a wine to expand and contract, dislodging the cork and increasing its chance of leakage."
– Wine Guardian® Wine Cellar Cooling Units

This highlights why consistent, controlled temperatures are essential for long-term storage.

Professional Storage Tips

To counter these risks, a dedicated wine storage setup can make all the difference. Key considerations include:

• Keeping the environment dark, vibration-free, and odor-neutral
