How to Protect Heat-Sensitive Items in Container Self Storage This Summer

When summer rolls in and the temperatures start to rise, container self storage becomes a handy solution for freeing up space at home or during a move. But what happens to those heat-sensitive items you’ve packed away? From electronics to antiques, some belongings need a little extra care to stay in good condition when stored during the warmer months.

Whether you’re using container self storage in Essex or looking for London self storage options, here’s how to keep your valuables cool, calm, and collected all summer long.

1. Know What Doesn’t Like the Heat

Before packing up, take a moment to consider what you’re storing. Some common heat-sensitive items include:

• Electronics (TVs, computers, games consoles)
  
  
• Vinyl records and CDs
  
• Candles and cosmetics
  
• Photographs and important documents
  
• Antique furniture or artwork
  
• Wines or perishable goods (though these generally need specialist storage)
  
  

If it can melt, warp, crack or degrade in high heat, it needs extra care.

2. Choose the Right Storage Provider

Not all container storage is created equal. If you're looking for self storage in Essex, check whether your provider offers insulated or temperature-moderated containers. While full climate control may not always be available, some storage companies provide shaded or well-ventilated units that help buffer extreme heat.

If you’re unsure, just ask — a reputable provider will happily walk you through the options and help you pick the right solution for your needs.

3. Use the Right Packaging Materials

Skip the bin bags and thin cardboard – instead, go for quality packing materials that add a layer of insulation and protection:

• Bubble wrap for delicate items
  
• Plastic storage bins instead of cardboard boxes
  
• Thermal covers or blankets for electronics and furniture
  
• Silica gel packets to absorb moisture and prevent mould
  

Label heat-sensitive boxes clearly so you or your movers know they need gentle handling.

4. Keep Things Off the Ground

It might sound simple, but raising your items off the floor can make a big difference. Use shelving, pallets or even sturdy boxes to allow airflow underneath your belongings. This helps reduce heat build-up and protects from any unexpected condensation.

5. Avoid Long-Term Storage for Certain Items

Some things just weren’t meant for long-term storage during a heatwave. If you're storing items like candles, certain cosmetics or perishable food, it's worth reconsidering. Either opt for climate-controlled facilities (where available) or find a cooler, more stable environment – like a home cupboard – for those few finicky items.

6. Visit Your Unit 

If you're worried about your items, pop in now to check on things. A quick visit can help you catch any potential problems before they escalate – and give you peace of mind during those hotter months.

Container self storage is a smart, cost-effective way to free up space – but as with anything, a bit of planning goes a long way. Whether you’re using London self storage or our container self storage sites in Essex, taking a few extra precautions during summer will help ensure your heat-sensitive items come out looking just as good as when they went in.
