Foam for board
Looking to build my own...what's the best place to get a block of foam? and what am I looking for?

Do you want to start with a block of foam, or a pre-shaped surfboard blank? Indiana?
I did a search for local foam insulation panel suppliers and started visiting their websites and making calls to see who had what I was looking for, and if they didn't, I asked if they knew of anyone to contact. A yellow book search for foam insulation suppliers will yield a bunch of local results too.


I used 2# EPS foam

Yeah - good sources for EPS foam. There are principally two foam types that you should restrict your choice to: the EPS that Scott mentioned and Polyurethane. 2+ pound density will work just fine. PolyU comes in densities up through 12 pounds and is fairly easy to locate locally (sign manufacturers carry it). You can laminate PolyU with Polyester resin or Epoxy. The other foam is EPS Expanded PolyStyrene - what we typically call beaded white foam or styrofoam (although that is incorrect). You can ONLY laminate EPS with Epoxy because the styrenes in Polyester will melt the EPS. Like Scott mentioned, most insulation companies carry it, just be sure to ask for 2# or higher. I think that 1 and 2 pound is pretty readily available and 3 pound or higher takes some searching. Brewketle uses 3 pound foam and may have a source for you. I have had good luck with Architectural Foam places, also. They carry 1, 2 and 3# in my neck of the woods.

Stay away from XPS which is the blue and pink insulation foams found at the big box stores. Pink from Corning and Blue from Dow - Dow calls their Blue XPS Styrofoam. It's NOT the same as the White EPS mentioned above. XPS is co-polymorized with polyethelene and nothing sticks to that stuff. Very likely that it will delaminate when warmed up in the boat.

There are a number of supply stores that sell close tolerance blanks. Foam EZ and Fiberglass Supply, I think, are probably the two most popular. They both carry PolyU and EPS blanks. Although they are both out here on the West Coast and most likely would double the cost of the blank to ship it. The close tolerance blank is molded to the basic shape of a surfboard, requiring less shaping to finish...and you pay for that convience. :)



Foam EZ is more businesslike, Fiberglass Supply has better prices, but are WAYYYYYYYY laid back about getting your order out. :)

I'm not sure if a Florida supplier would be cheaper shipping, but Surf Source is a reputable supplier.


Keep us posted on your build!

seems like I have a place to start with those tips. thanks for the input. I'll keep an update on the progress as I get going!

Google eps foam manufacturer in your area , it might be cheaper and you can pick it up , remember that 1 and 2# foam can be recycled by the maker so ask for virginstuff, 3# costs twice as much as 2# and is virgin cause it cannot be recycled.
