Sub floor in Basement
I'm installing 1X4's PT sleepers along with 3/4" sub flooring. Should it be installed in this manner: #1 vapor barrier #2 sleepers #3 insulation #4 floor or with #1 sleepers #2 insulation #3 VB, #4 floor??? Or does not matter? Thanks

CJK68,
It does matter - do the second plan - first is asking for trouble!
SLEEPERS - 1 X STOCK - W/T MATERIAL
Flat, dry, preservative-treated 1" x 4" sleepers in random lengths can also serve as a nailing base.
Begin by sweeping the slab clean, applying an asphalt primer and allowing it to dry. Next, embed the sleepers on their flat faces in rivers of hot (poured) or cold (cut-back) asphalt mastic, in rows 12" or 16" on center, at a right angle to the direction of the finished flooring. Stagger the end joints, overlapping the ends 4", with 1/4" space between. Use ramset to anchor.
Before installing the subfloor, install your foam insulation and loosely lay an additional vapor barrier of 4 to 6 mil polyethylene film over the sleepers, overlapping the edges on top of the 1 x 4s. Avoid bunching or puncturing the film, especially between sleepers.
Nail the finished flooring to the sleepers through the film.
Good Luck!

SUBFLOOR
I do not know if you started your floor yet, bit there is a relatively new product on the market called DRICORE. It runs about
$1.25 / sq $4.97 per tile at my HomeDepot. I did my reaearch on the product, incluuding talking to the manufacture and it seems great. Another benefit is it 7/8 inch vs 1 1/2 - 1 3/4 for a traditional sub floor. Check out my posting under insulation
posted on 3/15 I gaive more details about it. Or check thier website at DRICORE.com

CJK68,
You didn't mention what you intend to put down as finish flooring but what I am putting here is not designed for ceramics. All other flooring... yes.
I have attached a previous post that provides some great feedback which should be very helpful to you;
Quote:
Before you go spend a lot of money, please look into this. I'm glad I did. First I found this product called subflor, which appears to be very similar to the Dricore product. http://www.subflor.com/
Then I found that they wanted $9 a 2x2 piece (4 sq feet). WHOA. So I got some rolls of Delta-FL
http://www.deltams.com/deltafl/index.html and 4x8 sheets of 5/8 OSB which came out to be about a buck per square foot. I'm sorry I can't remember the actual price per sq ft for the Delta product, but I do remember it being less than a dollar.... Screwed it down with some tapcons and I'm good to go! Made my own 'Subflor' for half price!
I've looked into these two products as well. And had one comment. The big difference between dricore and delta-fl is that the dri-core panels will 'float' with thermal expansion and wouldn't take as much effort to 'level' them to irregularities in the concrete. Dricore is a subfloor on is own, But with deltams you need install a sub floor on top of it before your final finish.
I installed Dri-core, solid, VERY EASY to install subfloor!!! It took me and my wife (yes, my wife) about 5 hours for 300 sq. ft., with some cutting around pipes support poles etc. I thought it went well anf it looks and feels great. Just follow the installation instructions and ther will be no problem...Need to do the other 1/2 next weekend...will be putting wall up after that..i will keep all informed on how it goes...But I would recommend this floor to anyone...Thanks for all your input..
I like the idea of putting the walls on top of the dricore, which i will be doing..Should I get any dampness, (which I shouldn't bu if), the walls and toeplate are off the cement. I used 1x3's as spacers and the 3/4" space is just right. . Dricore suggest fastening the bottom plate to the flooring and then fastening the flooring to the concrete with 3 fasteners every 16 ft. I think itll work out nice. Let me know what you choose..and I'll keep you up to date on how the walls go up. In addition, i am not using baseboard heat so I did not have that worry, I am using a gas fireplace. Good luck..
I never contacted a flooring contractor about dricore. I bought 2 panels to show my General Contarctor, and he liked it, he had never seen it. From my understanding, it is made in Canada and is only available exclusively at Home Depot in the US. It is $4.97 for a 2x2 panel.
Advantages is that it is easy, solid, incorporates your vapor barrier and sub floor in one piece, allows the panel to "breath" underneath should you get dampness. I will now feel much more comforatble putting down carpet. Another point, it is dricore is only 7/8" high, where a true subfloor with sleepers etc is 2-2 1/4"..a big deal for me because of my ceiling height...
Had to use a few piece of leveling kit near the sump hole..$3.97 for a package of 20 pieces... Unquote
Hope this helps!

The www.deltams.com website actually says that a laminate floating floor can be installed directly on top of the Delta-FL product. And, it also mentions leaving a quarter inch from the wall framing for room to breathe without ever mentioning the need to screw anything down.
Does this make sense? You have used the Delta-FL product. Will the floor not move or shift at all with a floating laminate product simply laid right on top of it? I am planning on trying this to save a great deal of $$. I will let you know how it works out, but would still like your opinion. Thanks!
btw, I found the Delta-FL product for less than $0.53 a square foot.

i_hammer,
I just thought I would bring something up since you are also considering doing the delta flr application, please note the following...
"Most laminated flooring can be placed directly on top of DELTA-FL. For other floor treaments, DELTA-FL is covered with sheets of Tongue & Grove plywood subfloor or OSB. These are anchored to the concrete with concrete screws. Now the floor is ready for laminate carpet, sheet vinyl, or any other finish you wish!"
I have not used this but know of others that have. They are pleased but all applied the 3/4" T & G. Although the product says the above, I would install T & G to be safe than sorry. I would inquire with the manufacturer and go see some applications within your area before doing this type.
Just an idea!
