Reflective Insulation

What is the best insulation for a finished basement?

I want to finish my basement. It has poured concrete walls and no flooding or moisture I've noticed.. I've seen stuff about vapor barrior, and spray in insulation, and the roll out fiberglass batt insulation. Is there a best for the price insulation, + what about the framing for the drywall after the insulation? Do you frame before or after a spray in insulation?

1. When preparing to finish the basement you need to apply a vapor barrier to the concrete wall first. This can either be a spray on material or you can apply plastic sheeting to the wall by stapling it to the plate that is on the top of the concrete. Then you erect the studs these may be either standard wood studs or steel studs depending on your local code. After the framing is done then there are may different insulation materials available. I, myself, prefer foil faced rolled insulation at the highest "R" rating available. Ones this is done, foam fill little spaces as well as corners. Plumbing and wiring can now be done. The walls can now be sheet-rocked.
2. Rigid foam panels
3. The recommended is Spray foam seals everything. Also real foam panels caulked at all seams . vapor barrier and r value in one shot . The roll and batt insulation can leave air through and cause mold /dampness.
4. You can use Best Triple Expanding Foam Sealant. Price is good. http://www.amazon.com/gp/product/B00176L4DS?ie=UTF8&tag=digitsy-marina-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B00176L4DS
