Re: Reenforcing floor joists vs. thicker subfloor

I am not seeing the prices you are showing. I would use the Delta-FL as that is what it was designed for and Delta-MS was not designed for interior floor space.

I am getting the following breakdown:

Dricore:

130 x 6.48 = $842.40

Delta-FL:

2 rolls 4' 9" by 68' 6" x 193.52 = 387.04
2 rolls tape x 13.95 = 27.90
20 23/32 T&G sub floor x 29.47 = 589.40
20 sheets XPS = 319.68
Tapcons = 50

Total $1374

That is over a $500 difference. I cannot get the cost down as you provided. I think a good carpet padding then carpet ofr most areas will help a lot with the warmth factor too.

You can use DeltaMS. There is a huge thread on redflagforums (canadian forum) regarding using DeltaFL vs. MS, some people even called the manufacturer, to be told that the only difference between the two is that the FL uses new plastic while the MS uses recycled plastic. So there's a chance of a plastic smell on the MS. Personally I didn't smell anything on the MS i bought.

So that's 80$ difference right there. Also with the MS, you can just buy one roll and buy a small roll of FL to fill the last 100 sqft needed for about 70$. So instead of 2x 193.52$, you have 1 x 150$ + 70$ = 220$ vs your 387$, so 167$ reduction.

The tape is a bonus. You're sealing seams, seams that also exist with dricore (and that's a lot more seams).

The T&G, you seem to be taking the price of plywood and not OSB. Dricore is OSB. If you're on a budget, 8x4s 23/32 OSB is 20.39$. That's a 181.60$ reduction

XPS is an optional bonus that costs a lot and isn't comparable to the cost of the dricore. But already, with the reductions I mentionned, you're only at 151$ more WITH the XPS. Without XPS, you'd be at 168$ CHEAPER than Dricore.
