Look at a cardboard box that has been stored in a hot garage and the damage raises itself at first glance. Paper curls at the edges. Photographs amalgamate as ancient postage stamps. Vinyl records are distorted into other forms that they were not intended to be. Heat and humidity are little termites, with such a gradual, imperceptible action, that they never bring the fatal blow to their prey at once, but wear away the structure bit by bit until the damage is completed. Mini storage that is controlled by climate has been put in place to prevent just that. Click resources!
Imagine a stable room with a self-behaving air. The temperature remains the same at each season. Whatever happens outdoors, humidity takes care of it. No summer spikes and winter drops of frozen nature. Furniture is in a setting that is more reminiscent of a cozy living room rather than an abandoned shed.
Furniture of wood is especially responsive to such stability. Timber is sensitive to the environment by nature, it swells when it is wet and shrinks when it becomes dry. Put a solid wood dresser in a free-to-go unit and the drawers will soon become a daily war. The regular supply of the air moisture maintains the wood stable, the joints intact and the furniture practical.
There is an unspoken beneficiation of electronics. Vintage gaming consoles, unused monitors, old-time camera gear, all of these have the sensitive inner workings that are damaged by dampness. Corrosion is an accumulation process that is not visible. One day the power button is pressed and nothing happens. That risk is minimized by the stable air conditions.
This is known instinctively by the collectors. Environmental swings are prone to affect comic books, trading cards, vinyl records, and antique magazines. Paper easily absorbs the moisture and the pages will be distorted, the mould will grow and that damp odour will be present. Through climate-controlled storage, the pages stay flat, colour bright, and collections actually preserved and not stored.
Clothing benefits as well. Too much heat dilutes fabric. Leather dries out and cracks. Even the most well-cut clothes that have been kept under the influence of temperature extremes over the years are gradually losing their quality. Controlled situations retard that decay to a great extent.
Having the practical convenience of going to an air-conditioned indoor facility in summer also exists. Whoever has ever opened a metal storage unit in July, can attest that it is like an oven that has been heated. Surfing via boxes is a nasty task. The visits are much easier with climate-controlled facilities.
It is supposed that some are used to assume such care is applied to high-value antiques. As a matter of fact, even mundane objects have to be preserved as well: family albums, personal papers, instruments. A guitar that is stored in the air which is humid bends very quicker than any common person would anticipate.
