you can go by AC ratings if you want, but remember, there are much more factors that determine a good floor.

I am not familiar with AC rating as I should, and I will do more studying on it right away, and see if I can get back to you quickly.

Perhaps this site can answer your questions.

Thanks folks!

To add to Teetorbilt's comments, here is a quote from that website:
<i>
Any laminate flooring you buy in North America will (or should) have an AC Rating based on standards devised by the European Producers of Laminate Flooring. These ratings are really a ranking system that indicates how a product compares to others like it.

The AC Ratings involve numerous quality-control tests that cover such things as a product's resistance to abrasion, stains, burns and even furniture marks.</i>

This would seem to indicate that if two floors have the same rating, they should be pretty close in quality because the standard is verified by third party (depending on who says floor x is ACx).

And to further add to the point, it seems to me that the ratings are for the surface only.

what about water?
what about impact resistance?

I guess that would mean Wilsonart Classic would rank the same as Pergo Original, but in fact Wilsonart is a high pressure, which deals with impact resistance way better, so there goes the AC rating right there.

AC, DC, this is all dragging on my PC.

Just want ya to know I'm here.

I can critisize Pergo all day long, im not saying they are a bad company, but because Pergo was the first company in America to introduce laminate flooring, naturaly every one calls laminate Pergo.

The public is like a heard of sheep, one goes, all go.
