Welcome to the Q&A Forum

Just FYI, noindexing to handle duplication isn't really best practice now and isn't advised by Google. Rel=canoncial is there to help with duplication issues.And you certainly don't want to be implementing iframes to your site to try and get around this -Andy

If you are looking to disallow url parameters you could use something like the following as a convention. Disallow: /?  or Disallow: /?dir=&order=&p= if you wanted to be more accurate with specific parameters. There have been a few Moz questions of this type over the last few years, if you do look to remove the parameters. Also try and ensure that the product pages you have listed are well canonicalised and point to the original product etc. A good review on how to do this can be found here. This will in most cases be enough to remove any indexation/duplicate issues.
