Over the course of the summer it is not safe to leave works of art, especially works on paper, in an un-air-conditioned apartment for long. Damage can occur in just a few days. One way to keep electric bills down (and reduce the carbon footprint) when one goes on a trip would be to store all vulnerable works in one room and air-condition and de-humidify (if necessary) only that room.
Vacation homes may be subject to certain risks to artworks. In mountain homes at high altitudes, sunlight–especially the UV component–becomes an even greater issue than at sea level. And the seashore environment too is a threatening one for works of art; the sunlight is intense and the air is salty as well as humid; a potent mix that threatens artworks with rapid deterioration. De-humidification and limiting exposure to sunlight are even more important in such conditions.
In general, if you’re going to be away from home this summer, it’s a good idea to cover vulnerable works of art that will be exposed to daylight with a cloth cover that’s light-proof. We’ve been working on a design that can be fitted to the size of the artwork, though we haven’t put it on the market yet. Please let us know if you would like to hear more about it.
