This stuff has more uses than Duct Tape. We recommend it for economical padding on coolers and dry boxes. Ethafoam is a closed cell foam. The density of this material is 2.2 pounds per cubic foot. One 2" block weighs just 2 lbs. H2 Glue works well if you want to adhere your ethafoam.

Dimensions:
1" = 1" high X 12" wide X 54" long
2" = 2" high X 12" wide X 54" long

We fold the foam for shipping. Please specify in the Shipping Comments section during checkout if you would like the foam shipped flat.

    Q:

    I need to replace the foam padding on the crossbars of my canoe trailer with something more durable. Is Ethafoam durable enough or should I look at something like minicell?

    Thanks.

      Ethafoam is very dense. I think it would work perfectly.

      A:

      I used it for inside padding for a Korg synthesizer, but had a piece outside on my deck for two years protecting my deck from some propane cylinders (don't ask).
      Rain, UV light, heat, cold. It's held up well enough that I finally used it for another project.
      I think this would work for you.

    Q:

    I would like to use it on my dinghy (outside, contact with water) to increase stability to replace the traditional air tubes that are bulky and prom to deflate. Any comments? Can I use screws with large washers to fasten to the dinghy? Thanks for any help.

      A:

      Good Morning,
      I used it to make an extension for the seats in my canoe since they were already made from the same type of foam. The whole canoe is also lined with the same foam. I used large fender washers with bolts and H2 glue. Haven’t had any problems yet. I would think it would work fine for what you are asking. I am very pleased with the final result. It does seem like a high quality product.
      Good luck,

      A:

      It is a closed cell foam, but will absorb some water over time. I can't say how long it will give you good service continually submerged in water.

      A:

      Sorry, can't help you.
      I bought this material for lining a shotgun case I turned into a carrying case for a sythesizer/keyboard.
      If it DOES help, I've had a scrap piece outside on my deck for most of a year for soundproofing a 1200 watt generator (we get frequent power outages here just outside DC) and it's held up well without fading, deteriorating.
      I suspect you could use some bronze or stainless screws/washers and the material would hold to your dingy really well.

            Comments about Ethafoam Blocks:

            I bought a block of 1" ethafoam to line a small hardcase bag to make a range bag for my pistols and ammo. The ethafoam was easy to cut to the shape of my pistols and with a little imagination, it was exactly what I needed to form pockets to hold the pistols safely in place. It's sturdy yet slightly flexible and I'd recommend it to anyone.

            The ethafoam was delivered as promised. I'll use NRS again for further purchases.

              Used these 12 inch wide and 56 inch long by 2 inch think planks to replace the inflatable floor of my Tributary Tomcat inflatable kayak. Two layers thick. Had to trim the ends to fit the shape of the zipper pocket. Haven't paddled it yet, but if this works out, will save me a considerable amount of money to replace the original floor. I love AIRE products, but wanted to try and fix my leaky original floor with something different. I'm optimistic at this point. Just needs to warm up a bit and I'll see how it does around the hole at Boxcar on the N. Fork of the French Broad. And a BIG THANKS to NRS for NOT folding these planks in half for shipping...

                Comments about Ethafoam Blocks:

                I love the lightweight-ness of the product. For making a cookie pillow, you would have to somehow join widths together to get it wide enough. I'm sure it's doable, I just haven't had time to figure out how to join and then trim while keeping the integrity of the join. Word of warning, though. Recommend white for bobbin lace purposes as the material will sometimes pull out with the pin and black will show up in your work.

                  These blocks of foam are used in a local high school in a composite boat building program as seats and back rests. They work very well and are cost effective.

                    A thousand years ago, I used ethafoam in white water K-1 and C-1 building & boating. Recently I needed something stiff and lightweight and simple to shape to support heavy recorders I use to play early music. Finally I thought of ethafoam and scoured Whatcom county for a supply - even REI. NONE. Then I remembered NRS, and voila, here it is (again). It works great, again. A simple covering takes care of the only drawback.
