Personally, I'd just leave the TBOLT to get on with the job. It's probably a good idea to exclude draughts, but adding further insulation will probably not help matters and may hinder them. I'm thinking specifically of what happens to the ambient compensation of OCXOs when the insulation thermal resistance (and thus the thermal gradient to ambient) differs materially from when the unit was calibrated.
