Hi there. We live in a newly constructed condo that has no insulation in the interior walls (like between the bedrooms). Is this standard? We do have forced air heat, so I’ve heard that this is the way to go in that situation. That said, sound really travels throughout the apartment and I worry that heat doesn’t stay in bedrooms and that there is no fire retardant in those walls.

Does anyone have thoughts? Should we insulate these interior walls, and if so, with what product?

Thanks for any help.

  1. I don’t think insulation is the issue. More like thin sheetrock walls and flimsy doors. Old plaster walls do more to deaden sound.

  2. My condo has the same issue; lots of windows and very poor insulation. You can actually feel cold air blowing in. The floors are freezing – hardwood over concrete – and even when the thermostat is set to 74 degrees I have to wear sweaters. It’s awful. We are paying for an energy auditor in the hopes we can figure something out. I understand from neighbor that the summers are equally often with heat/humidity getting in….

    amazing how much developers put into looks and so little into substance!

  3. A standard developer is not going to pay extra for something they feel will not generate extra dollars. I always spec it, but it is up to the owner to want to actually pay for it. Insulation for heat on interior walls is not required only to help with sound deadening.

  4. In good quality new construction interior partitions will have sound/fire batts and double layers of sheetrock mostly for soundproofing and a substantial feel. But neither is required.
    If your heat is balanced and you heat the entire apartment the insulation is not needed to retain heat.
    For sound deadening Quietrock or Green Glue are your best solution.
