insulation in walls?

Question

Can anyone tell me if this is worth the cost of getting it done? Did you notice a big change when done? thanks

I am looking at getting the foam insulation oozed into my walls. This will be on top of the normal insulation. I am just wondering if it is worth the extra cost.

Answer 1

You would do better to add an additional layer of insulation in your attic and install a ventalator fan. As stated in an earlier answer, putting in the foam into your walls will cause you problems later on. And the decision is irreversible.

Answer 2

The foam is great for the outside walls. It is not in my opinion worth the extra costs to put it in interior walls.
One major drawback is this, if you ever need to run an additional electrical circuit, television cable, telephone line or other utility line or wiring inside any of those walls forget it, cause it is next to impossible. If this is new construction then you may want to specify electrical wiring and other utility wiring be done in conduit on the walls to be foamed.
The expanding foam is what is used for large commercial freezers and coolers.

Answer 3

You need this not only for heat value but also for some type of extra sound barrier between the rooms. If will save you in the long run. Cellulose, rock wool, fiberglass, or the new spider products are all good. Cellulose is the cheaper product.

Answer 4

Have them do the foam it's the best

Answer 5

well yeah on heating & cooling
