Why Some Items Need Special Care

Climate-controlled storage is essential for preserving items that are sensitive to temperature and humidity fluctuations. Here are just some of the numerous items that typically require climate-controlled storage in Cape Town: furniture, electronics, artwork, antiques, musical instruments, vinyl records, photos and documents, wine, household appliances, leather goods, books, business inventory – the list goes on and on! The reasons for needing climate-controlled storage particularly involve concerns about:  

  • Temperature  

Many items are sensitive to temperature fluctuations, and high temperatures in particular. Wooden or wicker furniture, musical instruments, vinyl records and electronics can be damaged by high temperatures that can cause warping and distortion. Some materials like plastics and metal can even melt under high temperatures. 

  • Moisture 

Fluctuating or high levels of moisture and humidity are very damaging to items in storage. Moisture can seep into many materials, causing them to warp, swell, and degrade. Metal objects can rust and corrode, which weakens the metal. Organic materials like wood and paper are particularly vulnerable, as moisture causes the growth of health-threatening mould and mildew in upholstered furniture, mattresses, and clothing. Humidity can also affect electronic components, leading to short circuits or other malfunctions. 

Items that Require Climate-Controlled Storage

Here are some items that should always be stored in climate-controlled storage:

  • Electronics and Appliances: Items like computers, laptops, kitchen appliances, TVs, and monitors are highly sensitive to temperature and humidity. Moisture can cause corrosion and electrical malfunctions, while extreme temperatures can damage internal and external components.
  • Wooden Furniture and Antiques: Wood is susceptible to warping and cracking under fluctuating temperatures and humidity. Antiques, made of very old materials and finishes, need a stable environment to preserve their value and prevent deterioration.
  • Artwork and Collectibles: Paintings, drawings, stamps, coins, and memorabilia can suffer from colour fading, paper degradation, and material breakdown under unsuitable environmental conditions. Climate control is vital to maintain their condition and value.
  • Musical Instruments: Instruments like pianos, keyboards, guitars, violins, and other stringed instruments are particularly sensitive to changes in humidity and temperature. These changes can lead to warping, cracking, and detuning, affecting both the instrument’s sound quality and structural integrity.
  • Clothing and Fabrics: Leather goods, furs, delicate fabrics, and textiles need a controlled environment to prevent mould, mildew, and colour and fabric degradation. 


Do TVs need climate-controlled storage

Absolutely. Televisions, especially those with LCD, LED, or plasma screens, are sensitive to extreme temperatures and humidity. High humidity can lead to moisture buildup inside the TV, causing components to corrode or short-circuit. 

Do books need climate-controlled storage?

Yes! Books are particularly susceptible to damage from humidity and temperature fluctuations. High humidity can lead to mould growth, cause the book boards to warp, and cause deterioration of the paper, ink, and leather bindings. Extreme temperatures can cause the paper to become brittle and the ink to fade. 

Tips for Storing Items in Climate-Controlled Units

  • Proper Packing and Insulation: Utilise appropriate packing materials like bubble wrap, packing peanuts, or foam pads for fragile items. Books and documents should be stored in plastic containers to protect against moisture. Items like furniture need breathable covers to allow air circulation.
  • Monitoring Temperature and Humidity Levels: Regularly check the temperature and humidity levels within the storage unit. Ideal conditions usually involve maintaining a stable temperature range and a humidity level below 60% to prevent mould and mildew growth.
  • Regular Maintenance and Inspections: Inspect your stored items regularly for any signs of damage or deterioration. This is especially important for electronics and antiques. Ensure the storage unit’s climate control system is functioning correctly and address any problems immediately.
