Underlayment under laminate


I am installing Toklo 12 mm AC5 rated laminate in a commercial area. It has a 15 year commercial warranty (lifetime residential also) and states to be better at repelling moisture. I found it here for $1.57 sqft.

http://flooring.builddirect.com/Lami..._10068424.aspx

I am planning to use cork underlayment sheets and a 3 in 1 barrier. Is this overkill?

The accoustical underlayment barrier I'm using is accoustical foam with moisture barrier 3 in 1. Don't really have too much info on it...just that it is sold with the Toklo flooring through the Build Direct site @ $.30/sq.ft.

I was additionally planning to use cork underlayment sheets. The cork underlayment sheets I'm planning on using are 6mm 2'x3' sheets @ @.60/sq/ft. I could also use the 3mm sheets instead @ $.49/sq.ft...or no cork sheets at all and only use the 3 in 1 barrier. Just trying to make it less noisy for the chiropractic office below me, but the cork isn't really necessary.

It is on the second story of a commercial building. Ugly carpet & linoleum currently, but with very high quality thick wooden baseboards. Going to try to use quarter rounds with the baseboards so I can keep them. Wood-subfloor underneath (I have been told by the property manager - still need to pull up some of the carpet to make sure). Northern CA climate, very moderate, not very humid, some moisture probability in the space. Going to be used for an appointment only personal fitness studio (focusing on yoga/pilates type classes - no heavy machinery/heavy weights).

Cork or no cork? Any advice? My husband is great at many things...but not very handy or knowledgable when it comes to these kinds of things. Relying on you guys!!!

Hey also...how much extra laminate should I buy? The space is actually 1252 sq. ft. I was planning on buying 1400 sq ft of laminate and cork. But would 1300 sq ft be enough? Thanks!

Cork or no cork is up to you. Having the cork is prob a bit of overkill. If this is in a commercial application, there probably won't be many people walking around barefoot, so warmth doesn't need to be top priority. Laminate can be installed over any flat surface (except carpet) As long as your sub-floor is true, flat and dry you can install the laminate right over the top, without having to worry about the sub-floor. Also, being on the second floor, the warmth from the first floor will help warm your laminate as well.
1400 sq ft should br fine. Generally you figure for about 10% for waste and cuts and such.

Good Luck!

Underlayment under laminate


Just finished my family room and discovered my Pergo was just under 4 ft per plank, not the full 48 inches I expected when layed flat. My room was exactly 20 ft in length so this was tricky and the old baseboards were too thin to cover recommended end spacing.

In my case, Pergo recommends a 4-3-2-1 ft length stagger pattern so I was lucky. Check your stagger pattern. I found it was worth planning for joints near heat vents etc before starting. Check the squareness of your room and allow for extension into doorways as you don`t want to finish with squeezing a 1 inch butt joint in at a wall.

I got lucky, almost Zero waste in a 12 x 20 room except a 2 inch wide strip edge in room 1, but my wife is annoyed and told the neighbours I spent 2 hours just staring and pacing the room and wasted graph paper planning my layout...

FYI my boards had a continuous running pattern 8 boards to a box. Because I used plank type I chose to scramble and shuffle the 8 patterns
which looks more natural to me. Good luck.

Thanks! I'll update you on how it turns out! Still not sure about the cork...I know the chiropractor downstairs would probably appreciate it. I think I'll make the decision once I pull up the carpet and see what I've got to work with.
