Most art handling companies employ equipment that monitors and applies cold or heat to the cargo area when outside conditions require it. Some truckers can offer fully climatized service that maintains both the temperature and the relative humidity, although this is usually only available in tractor-trailer sized vehicles and at extra expense. Temperature control is maintained by a thermostat and switches on and off based on the temperature outside of the truck. A truck with this type of equipment must also have an insulated cargo body with well-sealed doors in order to keep the environment maintained. All of A4's trucks have temperature control with extensive custom insulation and sealant built in to the cargo areas.
Many items can suffer when exposed to extreme heat or cold.
Wooden antiques react terribly to freezing temperatures as the joints can expand and crack, while some paintings do not fare well in extreme heat as the canvas behind the paint can settle improperly. While normal changes in the weather usually do not pose a risk, extremes can be harmful. However, it is a sad truth that no equipment can control Mother Nature. A4 advises that customers consult with us about any items that need special attention. We believe that the best protection is in the packing and we advise that exceedingly fragile items be crated to afford maximum protection while in transit.
