Attic door insulation
I live in a house that was originally build as a 1-story house. The previous owner added a room to the back of the house, as well as an extra room above that room that also leads to the attic (hope that makes sense). At first, this addition had no heat/air running to it, but I added that after I purchased the house. The thermostat and return had to be put in the upstairs "loft" beside the door that leads to the attic. This is a regular door (not a pull-down). I'm concerned that, since the thermostat is right beside the door, it causes the unit to run more frequently. Is there a way to insulate that door so that it won't allow as much heat or cold to affect the reading of the thermostat? Sorry this was so long, and hopefully it makes sense. Thanks.
