Interior Walls

We're building a house in Texas and they have just finished insulating and are beginning drywall. I noticed the interior walls weren't insulated, just the exterior walls, ceilings, and attic. The builder says they don't usually insulate the interior walls. I'm almost afraid to hear what the opinions of this message boards are... Does what he says sound reasonable? The house is 5000 square feet and not something we would want to shave costs of by improper insulation - I just hope the builder isn't cutting corners. It doesn't seem the case with other areas of the project, but this just struck me as strange.

Interior insulation helps with sound control, but unless you wnat to have one room hot and another cold, there's no reason you need it for thermal issues.

Like said, insulation on inside walls fine for just sound. If so get it with no paper on it.
5000 sq ft home ,only if you think you might close off a room or two in the winter. Then you could put some in the inside walls.

While your contractor is correct, that it is not a common practice, in general, in residential construction.
It is not uncommon in higher end homes, where a quieter interior ambient noise level is sought. Where the distinct individual life styles of the occupants are shared, not necessarily by others.

Aren't kids fun.

Thanks guys. We only have one kid, so if she gets too noisy we'll stick her at an end of the house by herself. The main concern for noise is the media room, but it backs up to an unfinished bonus room, so I have access to multiple sides and can insulate it myself later.

Thanks for the advice!

Thanks Ed and the rest for the great advice. I know you probably get tired of repeating yourself every few months so I was reluctant to ask about soundproofing (i.e. paper or no paper). Great to find somebody with a similar question.
