    I fashioned a DIY roof rack and used pieces cut from this NRS foam (with a coping saw) for the supports between the roof and the wood cross pieces of the rack. I used NRS webbing and cam buckles to attach the contraption to my minivan. So far it works great! I was happy with the easy of ordering from NRS and the quick service.

      • Minicell Foam

        Q:

        Can this foam be used to support a kayak on a vehicle roof with no roof rack? Kayak is 16 feet long and weighs 60 pounds. If not what density foam is required?
        Asked on 8/11/2016 by Tom from Maine

        14 answers

        • VERIFIED BUYER

          A:

          This foam is dense enough to keep the kayak off the car roof to keep it
          from getting scratched, but will not suggest what you intend, especially if
          just using one piece of foam, is safe or will not dent the roof. That
          said, I can't even imagine how you plan to tie down the kayak using this
          foam. Even with bow and stern lines, if you plan to travel over 40 mph,
          the kayak will react to the air flow. and twist side to side especially
          with the draft from other vehicles. It is possible the kayak would twist
          back and forth enough to slide off the foam. In a strong cross wind, I
          have had kayaks slide off a cradle version of this type of foam
          specifically designed for cross rails.
          I would call NRS and ask for expert advice. My experience is they want to
          help and will not try to hard sell you anything. I would likely steer you
          toward the deluxe kayak car rack from NRS which was designed to safely
          transport kayaks that don't have rails or crossbars. It has the foam you
          need in addition to straps. Without crossbars in addition to bow and stern
          lines you will also need straps that cross the kayak and go through the
          window openings, both front and back. To reduce side to side motion, I
          would also recommend using a double bow and stern line which looks like an
          inverted V once tied down. You can also use Easy Liner select grip, used
          as a drawer/shelf liner, sold at Walmart to maximize the grip of the foam
          to the roof, underside, and foam to boat, top side.
          Oh, NRS calls it non skid foam blocks. Minicell foam after multiple uses
          will compress to the point it is slippery, thus the recommendation of the
          Easy Liner. They also only include one cross strap with the kit. I highly
          recommend two.
          Be safe, and good paddling to you.

          A:

          No, that's not what this foam is intended for, nor is any foam. The center
          area of a vehicle roof is not made to support weight. That's why roof racks
          are attached at the edges of the roof, where there is sufficient structure
          to support loads. Get a roof rack. It does not have to be a fancy high end
          rack, there are very simple systems that use standard pipe and some
          specialized clamps, but you need a rack of some kind if you want to avoid
          damaging your vehicle and/or boat.

          Hi Tom,
          It can easily support a kayak without compressing too much. I use it on the load bars of my truck for hauling sea kayaks, and I've made cradles out of it for when I'm traveling to haul my surf boat on top of rental cars.
          Make certain there is no sand, etc., underneath or it will scratch the roof of your car.
          Hope this helps,

          A:

          I personally would always use a proper rack for transport but if for some reason that was not possible, this foam would have the density to support the weight of your boat. I would also be cautious about roof depression as the weight of you boat plus the tension you'll need on the lines to secure the boat might be reaching the roof weight load when car is at speed.

          Would not recommend. Any moisture between the roof and the minicell it would be sliding all over the place. Even if there's no moisture it would be very difficult to cinch it down to prevent it from moving.. I was lazy and tried it that way once in the first corner I took the wind hit it and just slid around on the roof

          A:

          This foam will definitely be strong enough. Just make sure your car roof can take the weight of your boat without denting. The larger the surface of foam under the boat, the more the weight is distributed. Consider a piece up near the front, and another near the back of the roof.
          Once secured, check the tightness of your straps on occasion as the foam may settle a little causing some slack. Having a secure boat is a big safety concern at highway speeds!

          I don't know how to calculate the amount of foam needed, but this is as buoyant as any product I know of. It can be easily cut with a kitchen knife, and pieces can be glued together using common contact cement. This is really superior flotation!

          A:

          Matt, a 3" x 12" x 12" piece of Minicell is 432 cubic inches, or 1.87 gallons in volume. A gallon of water weighs ~ 8.4 pounds, so that block of foam would displace a bit less than 16 pounds of water. Discounting the weight of the foam, it would take about 5 of those blocks of foam to support the weight of your boat. I suggest you check out our canoe float bags for safety flotation for your boat - http://www.nrs.com/category/3049/kayak-touring/flotation?f-boat+type=canoe

          Dear fellow shopper:
          I am having to make some assumptions here as I don't know the weight of your gear or yourself, but I think this will give you the tools to figure the total amount of minicell foam needed.
          Rough Numbers:
          Water weighs about 61#/ft3
          Minicell foam weighs about 3#/ft3
          1 cubic foot (ft3) of minicell foam then would be about neutral buoyancy at something less than 58#.
          Assumption: 85# canoe plus 50# plus 150# person equals about 285#. 285# divided by roughly 50# (minicell buoyancy) equals about 5.7 cubic feet. If you just want your canoe and assumed gear 85# plus 50#, then you would need only 2.7 cubic feet of minicell foam.
          Assuming that you are probably doing light white water, remember for the foam to do any good, it must be strapped or attached to the canoe. If the foam floats free of the canoe, one become the proud owner of an expensive river bottom decoration.

          This minicell is a rather dense material. I would purchase what you think you need then cut or glue up to fit. You may wish to sculpt this slightly to conform to your personal needs with very sharp tools. Of course, this depends on your weight and size.
          As far as adhering minicell to your kayak, personally, I would try out using it on several trips before permanently adhering to the bottom of my Kayak. Most marine adhesives (like goop) including H2 want to hold things really well. A light application of rubber cement hold your minicell in place for several tryouts. Then, affix with a real adhesive.

          Jack, we aren't able to cut it for you but it cuts easily with most power saws. A band saw would be ideal, but you can set up a jig to use a jig saw or skil saw. The blocks are 3" thick, so that gets you one of your dimensions. Please be aware of the bolded note on the product page, that states we fold 3' and 4' lengths for shipping unless you specify to ship them flat.

          This material can be cut and shaped with a number of different tools. I prefer a standard bandsaw, however, nearly any saw, such as a hacksaw, a carpenter's handsaw, copping saw, or a backsaw will cut this material relatively well. Typically, the finer the saw blade, the cleaner the cut.

          Yes, Brett, that will work with this foam. Cuts like butta. Does darken the surface.

          Yes this could be cut with a hotwire cutter. I would work quickly as it is very susceptible to deformation and deterioration when exposed to heat (though slightly less susceptible than styrofoam). Cutting with a hot wire or hot knife leaves a cleaner edge than other mechanical methods. I have used a saw and smoothed it up with propane torch as well. Best of luck.

        Q:

        I need a neck gasket form, & 2 wrist gasket forms. How much mini cell foam do I need? Is there anyway to buy pre-cut forms from NRS? Pay buy square foot + the extra labor? I will also be buying both wrist gaskets, & the neck gasket from you.
        Thank you for your time, help, & knowledge.

          Neck gasket openings typically vary from 9.5"-10" and wrist openings from 3.25"-3.75". You'll need a 2 foot piece of Minicell to get all three of them. We don't sell the completed forms but they're easy to make. Wrap them with nylon strapping tape to prevent the Aquaseal from sticking.

          Jim, Minicell Foam will work well for this; it is easily shaped. You'll probably want to first cut a template out of cardboard to get the right starting cross section. Cut the Minicell slightly larger, then trim to fit. You can't use a contact cement here; I believe Aquaseal Adhesive, Item # 35001.01, would work well.

          Hello,
          I assume your kayak is
          roto-molded polyethylene. The mini cell
          Foam makes a pretty good bulkhead.
          My Boreal Muktuk has mini cell
          Foam bulkheads. I have used a
          Sealant/adhesive called Marine Goop
          for bonding minicell foam. This is a
          Strong polyurethane product. Available
          In hardware stores. If you are replacing a
          Bulkhead make sure you are locating it
          As the original manufacture had it.
          If you are adding a bulkhead or relocating
          One you need to carefully consider
          What you are doing as this has an
          Effect on the stability and safety of
          Your kayak.

          Yes I think so. It is very tough stuff and should resist scrapes and
          scratches.

          It has good rigidity, but difficult to cut out straight cuts unless you
          have some sort of maching ability. Sands well.

          This foam would make excellent tool box dividers. It is a closed-cell foam,
          so it won't saturate with oil or grease (but it will stain). It cuts well
          with a serrated knife (a bread knife works great) and you can glue it in
          with several different adhesives (I've used contact cement and Shoe Goo).
          The only downside would be the expense, but if you are willing to spend, go
          for it!

          Joe,
          This is an excellent foam for many applications. I have used it primarily for outfitting the seats in my sea kayaks. As far as using this for shadowing your tool box I would think this foam is little pricy. Probably better off finding something less expensive. Seek out a foam products manufacture in your area to see if they have scrap pieces which they might be able to give you.
          Hope this helps.
