PolyFoam Multipurpose Foam Underlayment – 100 sq ft Roll for Laminate & Wood Flooring, Moisture-Resistant, Shock-Absorbing, Lightweight, Easy to Install, Made in USA

Good value worked for my purpose under carpeting

I'm using this as a layer in insulated curtains for our home and RV. It's flexible, lightweight, low cost and allows some light through, and can be layered with small bubble wrap and quilt batting between 2 sheets, muslin or light fabric for thermal insulated curtains. The overall curtain is pretty thick and warm, yet still lets some light through, and can be rolled or folded up when not needed.

I am not using this for its intended purpose, rather for resist material when wet felting. The packaging is not ideal, it comes wrapped in thin plastic that is only taped securely at the top. Mine ripped during shipment and left a couple tears in the first layer on the roll. The tape for the product label also ripped the foam when I tried to peel it off. This is easy to work around and only some was damaged. Overall its a very thin foam and will work well for my intended purpose, and it's a good value for the amount (at least compared to other foam sheet products). I wish the plastic it came packaged in was a thicker plastic, or taped in more areas.

Worked great under the flooring.

After our kitchen flooded and the Eucalyptus solid wood flooring warped, we replaced it ourselves. We removed the damaged flooring, dried the subfloor with fans, and used PolyFoam Multipurpose Foam Underlayment, which was significantly less expensive than contractor-recommended brands. We ordered new Eucalyptus flooring and stacked the wet boards to dry. When the new flooring arrived and acclimated, we alternated the best original planks with the new ones, creating an attractive, contrasting pattern that looked better than the professionals’ work. I highly recommend PolyFoam—it’s affordable and effective. We even used leftover underlayment and flooring to finish our master bedroom.

Works great specially the money you save on it yes it’s a lil had to keep in place but I rather deal with that or use painter tape to put together than pay for expensive I got all mine here for my whole house saved like $1500

If you buy it to save money comparing it to Home Depot’s kind-don’t, you have to double this up sometimes triple for transitions so in the end you need to use twice as much and it’s actually more expensive.

So glad I found these on here, we have been placing underlayment in our mobile home. Having these down first gives that extra barrier for moisture, was even able to double up in areas that needed leveling.

I use this underlay to create my resists for wet felting projects. Light enough to layout the wool and roll and it's thin enough to allow for the water to work through it/around it so that I can complete projects before removing the resist. Who knew? :-)

100 sq ft my arse my room 10sq foot and just did job very disappointed $100 feel ripped of

good price

Although this is on the cheaper side for what it is, for a few extra dollars you can get something A million times better. This was infuriating to work with but not impossible. It was way thinner than I had hoped and tore whenever I tried to slide the lament into place. Even some other options in a similar price range will come with tape to adhere it to the floor so it will not slide and stay in place but this DOES NOT. No adhesive and unless you tape it yourself this will move every which way and again cause issues in your projects. Buy and beware, it can be useful but for similar pricing there are some better options.
