Dear John, I would be useful to know what exactly is going to be stored.
However for basic useful information about temperature most objects with
the exception of painted and varnished surfaces can be stored in cold
temperatures. Oil paint gets brittle at around -5C and artist acrylics get
brittle at around +5C to +10C. So keeping that in mind every thing else can
be kept cool, say above freezing. This is a way of keeping the relative
under control, Between 35% RH and 60%RH in the wintertime.
If you have further questions please contact me directly.
Sincerely,
Marion

We are looking at taking a warehouse with no heat, etc., and dedicating
a portion of it
to storing museum property/artifacts/paper, etc. It will be walled
in, plus a heater/temperature
controls added. Presently, the items are sitting in the open
warehouse, subject to dust,
rodents, etc.
Does anyone have a recommendation on the standard temperature
parameters and/or what
type of unit would be required to meet these standards? The area will
likely be ONLY
15X15 feet in that range, so will not be a major heater/AC unit.
Suggestions are welcomed.
