How to Install Eco Cork Foam Underlayment?

Eco Cork Foam® (ECF) Underlayment provides unsurpassed support and protection for a variety of flooring applications, including vinyl plank (5mm or thicker), laminate, attached pad laminate, engineered wood and solid wood floors. ECF is engineered using a proprietary blend of polyethylene and granulated cork. It’s the only waterproof underlayment with a built-in 6 mil vapor barrier and works equally well with wood or concrete subfloor installations.

ECF Underlayment is the only underlayment that delivers 10 features with every roll:

1. WATERPROOF: The only waterproof underlayment with a built-in 6 mil vapor barrier. As a Class 1 vapor barrier, ECF can be installed directly on concrete subfloors, eliminating the need for additional vapor barriers.
2. ANTIMICROBIAL: Infused with Ultra-Fresh to inhibit microbial growth, thus helping to prevent any odor, staining and deterioration caused by mold, mildew or bacterial growth.
3. ACOUSTICAL: Third-party tested and verified for top-rated sound absorption. Eco Cork Foam's current validated acoustical ratings: IIC 73, STC 67 and Delta IIC 23.
4. ECO-FRIENDLY: ECF is non-toxic, family- and pet-friendly, and registers ultra-low VOC emissions. Exceeds California's strict indoor air quality standards.
5. INSTALL-READY: Patented built-in 6 mil vapor barrier with 4" overlap and self-sealing tape for easy installation. Cuts easily but resists tearing.
6. THICKNESS: At 1/8” thick, ECF provides cushion and smooths out subfloor imperfections.
7. STRENGTH: Tough, strong and comfortable support that extends the life of your floor. Protects tongue-and-groove connections, providing a solid, durable floor foundation.
8. LOAD: Promotes even weight distribution to prevent floor damage. Compression strength at 80% can carry a load of 17,633 lbs./sq. ft. using ASTM D3575. ECF supports pianos, gaming equipment, fitness equipment and more.
9. COMFORT: R-value of 0.48. ECF's proprietary blend of foam and cork is a natural insulator, while the 6 mil vapor barrier reduces drafts and diminishes the transfer of cool and hot air.
10. VALUE: All-in-one product. Buy the floor. Buy ECF. You're done! ECF is 360° protection for your floors, with quick and easy installation to save time and money.

Can peel and stick tile be placed over ECF in an RV setting with OSB subflooring? Gorilla construction glue the ECF to OSB an tile over? The main goal is to not only protect the subfloor from water in the bathroom/around shower, but to also hold some heat. The floors are cold. There's no existing moisture barrier in place either.

The video stated to place it flush to the wall. I have a concrete subfloor. Do I need to tape it down?

[faithhopelove]

Love the feel of this but so confused as to why the tape makes cork lifted..now we see all of those lines with vinyl installed..will this eventually settle?

Can I use it under low-profile 3mm carpet tile with rubber back? Need sound barrier. It's a second floor condo. OSB subfloor. Planning to staple down ECF, and put carpet tiles on top, using corner sticky adhesive tabs for tile corners.

If I have a plywood sublfloor that I've already put self leveling concrete down on, do I just follow the installations as if its a concrete floor? Asking because its not very thick and the underside of the subfloor is less than a foot from bare earth, Its a bathroom and i have moisture concerns

[grotesquecat]

Is it possible to buy just around 2x2ft of this from home depot? I don't need 70+ ft of this to repair a corner

[terrillmel]

Would you recommend using this under a nail down hardwood floor?

[matta]

So what happens when we have a plywood subfloor? We just ignore the tape and leave the sheets next to each other constantly moving out of place?

[birdsongvalley]

Can I use this over a hardwood floor that has no insulation underneath? I want to seal up a 100+ year old farm house floor. Too cold in the winter.

I don't need to tape the next roll on the right/left, I get it. But do I need to tape the next piece if the current roll is out and I need to start new one?
Or it has to be one piece from wall to wall?

[zombiewarking]

Should I use flooring primer on a concrete subfloor before I use this underlayment

[katlady]

If adhesive is present from previous carpet installation must it all be removed?

[bee_marya]

Do I need to tape it around the vent?
While I was cutting the laminate, I walked in on an Eco cork foam flying around because the heater turned on. Will this be a problem if the hot air will be blowing under the flooring?

[Ekinmedia]

Is it water proof? Can I use it for vinyl plank Flooring in the kitchen?

[DeadBunnyDoctrine]

How did I keep it from rolling back up

[kittNY]

Would this be good for lowes smartcore brand?
