Carol,
the temperatures you sight are very difficult to achieve indoors,
even in an unheated building. If it were zero degrees outside, it
would not be zero indoors unless this outdoor temperature was
maintained for a very prolonged period of time. Do you have periods
of zero degrees in Maryland for a week or more at a time? There goes
my fantasy of moving south :) this is simply because building
materials have insulating effects that will prevent the indoor
temperature from completely matching the outdoors. I have an unheated
garage here in New York. Temperatures are commonly 10-15 degrees
above exterior temps. Also keep in mind that wind chill temps will
not affect items stored indoors, simply because wind cannot penetrate
the structure of the storage facility.
Second, it is unlikely that the temps you cite would have any
negative effect on paraffin blocks. We typically ice them and I've
even known techs who placed them in a freezer prior to sectioning.
when I saw your subject header I thought you were inquiring about
high temperatures, which is a greater problem for most of us when it
comes to block storage.
I got the chills just thinking about those Maryland winters. Brrr.
