Insulating a "cold room"

[Jay]

Hello,

Wondering if anyone has some general info on insulating a cold room. This is a 41 degree (f) room used for commercial food preparation. New slab on grade construction. Wood frame walls, adjacent to other interior spaces with normal climate control. Second floor offices above. Central NJ location.

Looking for guidance on below slab insulation requirements, where that vapor barrier would go? Partition / ceiling insulation and again, the vapor barrier type and location. Being a cold room the conditions are kind of "reversed" from what I am used to with regard to the building, in this case the room, envelope.

Thanks

I think you need assistance from a design professional in that field, IMO.

Typical freezer slab configurations is as follows: Rat slab, rigid insulation (2-6+ inches), vapor barrier, and topping slab. Do not forget a thermal break under the walls and at any structural steel members.

A registered professional is needed for design.

Thank you for the feedback. I completely agree.... a design professional is needed here and I have mentioned this to owners more than once. Better to do it right the first time.

Be sure the check the International Energy Efficiency Code. The 2015 edition, section 403.2.14 - 403.2.16 gives motor efficiency standards and envelope r values.

Thanks! Will do. I have been having some difficulty finding a specialist of this sort here in central NJ. If anyone reading this knows of any cold room / vapor management specialists I could use a recommendation.
