Insulating refrigerated rooms
Ok, so the situation is a refrigerated interior room.
Location is the basement of a home in Portland, Oregon. Was advised on construction and insulation of the room already, but thought I’d like to find out if there is consensus among a broader array of people with experience.
Wine room with split system that cools and humidifies. Room is in the basement with one concrete wall and concrete floor. Frame in with 2×4 and add 3″ rigid insulation, foamed in place. Ceiling remains as existing with 2×10 joists and about 8″ of fiberglass insulation.
Greenboard on the interior walls of the wine room, standard sheetrock on the exterior walls. Walls primed and 2 coats of latex paint. Door with insulated glass panel and weatherstripping on all 4 sides.
Interior of the basement at about 68 degrees Fahrenheit, interior of wine room is 55 F, measured by liquid temperature. Humidity in the wine room should be around 65%, the average relative humidity for Portland year round averages about 69% by some accounts.
I’m wondering what details y’all would recommend in this situation. Not that there’s a problem, but it seemed like enough insulation, etc., but I’m wondering now (after the fact, of course) what would have been advised…
